Construction Additives & Reinforcement Fiber Solutions
Products
MICHEM’s product portfolio helps formulators and purchasing teams choose construction additives by the performance problem they need to control, not by product name alone.
Start Here
A construction additive is rarely purchased because a formulation “needs an additive.” It is purchased because something specific is going wrong or a performance target cannot be reached with the base binder, aggregate, filler and water alone.
In a tile adhesive, the visible problem may be early skinning, tile slip or difficult troweling. In a render, the issue may be fast water loss into a porous substrate, poor workability or cracking after cure. A self-leveling compound may flow well at first but separate, trap excessive air or lose surface quality. Concrete may need more slump without adding more water, or it may need better crack control after placement. These are different problems, and they lead to different product families.
The expensive mistake is to begin with chemistry rather than the failure mode. Selecting a higher-viscosity cellulose ether because “higher is stronger,” increasing polymer powder because adhesion is low, or adding more fiber because cracking is visible can move the formulation in the wrong direction. Each change can create a new processing or performance problem.
Use this page as the first decision point. Identify the material system, define the failure you need to control, then enter the product family that changes the relevant mechanism.
01
Product Family 01
MICHEM’s cellulose and starch ether range includes HPMC, HEMC, HEC, CMC and hydroxypropyl starch ether.
For cement- and gypsum-based dry mixes, cellulose ethers are usually selected because the fresh material must hold water long enough for hydration and application while maintaining the right consistency. Water retention matters when a mortar contacts an absorbent substrate or is exposed to conditions that accelerate evaporation. Rheology matters because the same mortar must often be easy to mix and spread while remaining stable after application.
Viscosity is therefore only one part of selection. Two cellulose ethers with similar headline viscosity can behave differently because the test instrument, solution concentration, temperature, substitution level, particle form and formulation chemistry are different. For incoming comparison, you should first confirm that viscosity values were measured under comparable conditions. For application selection, you should then evaluate water retention, open time, slip or sag resistance, wetting, workability and dissolution in the actual formulation.
HPMC and HEMC cover many dry-mix uses, while HEC and CMC extend the portfolio into coating and industrial systems. Hydroxypropyl starch ether can refine anti-sag behavior, workability or consistency without treating bulk viscosity as the only target.

Product Family 02
MICHEM supplies redispersible polymer powder grades positioned for multipurpose, flexible, hydrophobic and thixotropic use.
An RDP begins as a powder for dry blending, but its value appears after mixing with water and during drying. The dispersed polymer can form a polymer phase within the mineral matrix. That is why RDP selection is usually linked to adhesion, cohesion, flexibility, deformation capacity, water resistance, workability or combinations of these properties.
The key mistake is to treat all VAE-based powders as interchangeable. Polymer base is only the first screen. Minimum film-forming temperature, ash content, protective colloid system and functional design can point to different application behavior even when several TDS fields look similar.
MICHEM’s current technical documents include grades for general dry-mix modification, self-leveling systems, hydrophobic mortars and flexible tile adhesive applications. Product selection should therefore start with the required failure resistance. If the risk is tile movement or deformation, flexibility and adhesion under the intended service conditions become more important. If the risk is water ingress, hydrophobic behavior may move higher in the decision hierarchy. If the problem is vertical stability during application, thixotropic behavior may be more relevant than selecting the lowest MFFT.
Product Family 03
MICHEM’s concrete admixture portfolio includes polycarboxylate superplasticizers in flake and powder forms, together with melamine-based and naphthalene-based water-reducing agents.
A water reducer should not be selected from a headline water-reduction percentage alone. The useful question is whether the admixture can produce the required flow at the target water-to-binder ratio while maintaining acceptable setting, air content, early strength development and workability retention with the buyer’s actual cementitious materials.
PCE chemistry works largely through adsorption on cement particles and steric dispersion. Small changes in polymer structure can alter adsorption rate, initial dispersion and slump retention. Cement chemistry, sulfate balance, supplementary cementitious materials, clay contamination and mixing sequence can also change the observed result. This is why a superplasticizer that performs well in one cement system may not transfer directly to another.
Powder or flake form is also a process decision, not a performance ranking. Dry-mix producers may prioritize dry blending and dosing compatibility, while other users may evaluate dissolution or conversion into their own admixture system. Melamine- and naphthalene-based products remain relevant where their compatibility and cost profile fit the formulation.
Product Family 04
MICHEM’s fiber range covers polypropylene monofilament fibers, synthetic macrofibers, cellulose fibers, POM fibers, glass fibers and steel fibers, with additional forms such as hooked, twisted, embossed and wavy geometries.
“Fiber reinforcement” is too broad to be a useful specification. A fine polypropylene microfiber added for plastic shrinkage crack control performs a different job from a macro-synthetic or steel fiber used to increase post-crack toughness. Fiber length, diameter, aspect ratio, tensile strength, elastic modulus, surface geometry, dosage and dispersion all influence performance and processing.
The first selection question is therefore when the crack develops and what the fiber is expected to do after that crack starts. Microfibers can distribute a large number of fine filaments through the matrix and are commonly evaluated for early-age crack control. Macrofibers and steel fibers are evaluated where residual load capacity, toughness or larger-scale crack bridging matters. Glass and cellulose fibers serve different formulation roles and should not be treated as substitutes based on length alone.
More fiber is not automatically better. Higher dosage makes dispersion and finishing more demanding, and poor distribution can create local inconsistency. Any proposal to replace conventional reinforcement requires project-specific structural design and the applicable engineering standard.

Product Family 05
The MICHEM portfolio also includes defoamers, silicone hydrophobic powder, gypsum retarder, calcium formate, iron oxide pigments and related functional additives.
These products are usually selected after the main binder and primary modifiers are established. A defoamer must control unwanted air without damaging the air structure the formulation needs. A hydrophobic additive must reduce capillary uptake without disrupting wetting. Gypsum retarders and calcium formate are evaluated where set time or early strength needs adjustment.
Iron oxide pigments belong to the same purchasing portfolio but solve a different problem: color consistency. In colored concrete or decorative dry mixes, the buyer must control pigment identity, shade, dosage, dispersion and batch consistency rather than treating pigment as a cosmetic afterthought.
Decision Matrix
| Your formulation question | Start with | What to confirm in trials |
|---|---|---|
| Is the mortar losing water too quickly or becoming difficult to apply? | Cellulose & Starch Ethers | Water retention, consistency, open time, sag or slip, application feel |
| Does the hardened mortar need more adhesion, flexibility or water resistance? | Redispersible Polymer Powder | Bonding, deformation behavior, cohesion, water exposure, workability |
| Does the concrete need more flow without adding more water? | Superplasticizers | Water demand, slump, retention, setting, air and cement compatibility |
| Are cracks forming or propagating in mortar or concrete? | Fibers | Crack stage, dispersion, toughness, finishing and structural design requirements |
| Is trapped air, water absorption, set time or color the remaining problem? | Functional Additives & Pigments | Target property, interaction with the full formulation, dosage window and side effects |
This matrix is a starting point, not a substitute for testing. Commercial formulations often combine several product families, and the correct package depends on how those materials interact in the same binder system.
Find the Right ProductSupplier Comparison
A specification table can create false confidence when two suppliers use different test methods.
Cellulose ether viscosity is a clear example. A value measured at 2% concentration with one viscometer cannot be compared directly with a value generated using another instrument, spindle, speed, temperature or solution preparation procedure. The number may be precise while the comparison is invalid.
RDP data requires the same discipline. MFFT is useful because it indicates the temperature below which continuous film formation becomes difficult under the stated test conditions, but it does not describe adhesion, flexibility or hydrophobicity by itself. Ash content and bulk density are useful for identity and consistency checks, yet they do not replace an application trial.
For superplasticizers, industry standards such as ASTM C494 classify admixtures by concrete performance rather than polymer marketing language. That is important because water reduction, setting and strength are measured in a complete concrete system. For fibers, standards such as ASTM C1116 address fiber-reinforced concrete and shotcrete, while the suitability of a specific fiber still depends on its geometry, dosage and the design objective. Pigments for integrally colored concrete may be evaluated against requirements such as ASTM C979 where relevant to the project.

Qualification Workflow
Start with a written performance target. “Better workability” is not enough. Define what operators or QC staff will measure: open time, slip, flow diameter, water retention, wet density, air content, setting time, bond strength, early strength, water absorption, crack width or another relevant property.
Next, screen the supplier data. Eliminate products that do not fit the chemistry, application or required specification window. Where TDS values look similar, ask which application property distinguishes the grades and whether the supplier can provide a sample for side-by-side testing.
Run the first trial with controlled raw materials and a fixed mixing procedure. Change one important variable at a time. Construction additives are highly sensitive to cement, gypsum, fillers, sand grading, water quality, temperature and other admixtures, so a trial that changes several ingredients at once is difficult to interpret.
After the laboratory result is acceptable, confirm the material at production scale. Mixing energy, batch sequence and site conditions can expose problems that a small laboratory mixer does not reproduce.
MICHEM’s technical materials describe a workflow built around grade selection, sample evaluation and formulation support. Use that support to shorten the screening stage, but keep final approval inside your own production and application conditions.

Dry-mix mortar producers usually begin with water management, workability, polymer modification and set control. Tile adhesives, wall putties, renders, plasters, EIFS mortars, repair mortars, waterproof mortars and self-leveling compounds may use overlapping additives, but the decision driver changes by application.

Concrete and infrastructure producers focus more heavily on water reduction, workability retention, air, setting, crack control and toughness. Ready-mix concrete, precast elements, industrial floors, shotcrete, tunnels and pavements impose different requirements on admixture compatibility and fiber performance.

MICHEM’s published company materials describe more than 15 years of production and market experience, supply to more than 40 countries, more than 200 employees and total production capacity above 30,000 metric tons. These are company-level figures, not capacity claims for every individual product family.
The company also states that its management systems are certified to ISO 9001:2015, ISO 14001:2015 and ISO 45001:2018. These are management-system certifications. They should not be read as product certification for a particular grade, country or application.
For a buyer, the useful part of this structure is the qualification process around the material. MICHEM provides technical data sheets across its main product categories and describes support for grade matching, sample testing, formulation evaluation, packaging coordination and international supply. When a market requires a specific product certificate, declaration or test report, that requirement should be checked against the selected grade before the commercial order is finalized.
FAQ
Summary
This page identifies the product family that is most likely to control the property you care about. It does not replace grade-specific TDS review, laboratory testing, local compliance checks or production qualification.
MICHEM does not control your cement, gypsum, fillers, aggregates, water, pigment system, mixing energy, substrate, climate or application method. Those variables can change the result of an additive that performs consistently within its own specification. Final dosage, product combination and process settings should therefore be established in the buyer’s own formulation and confirmed before full-scale production.
The next step is to enter the relevant product family and compare the specifications that actually drive that application.
