Self-Leveling Underlayment Polymer

Polymer additive for self-leveling compounds—engineered to improve flow, adhesion, cohesion, and durability in floor leveling systems.

Formats: powder or liquid grades (per inquiry)
Documentation: SDS / TDS / COA on request
Supply lane: palletized export, drum/IBC, or bulk (as applicable)

This page describes typical performance contributions of polymer additives in self-leveling systems. Actual values depend on grade, binder type, fillers, and site conditions. We align the appropriate grade once we know your system details.

Product overview

Self-leveling underlayment polymers are used to upgrade the rheology and film-forming behavior of floor leveling compounds. In practice, the polymer helps the mix spread smoothly while retaining cohesion, reducing edge curl and cracking risk, and increasing adhesion to prepared substrates.

Flow + leveling

Supports smooth spread and surface finish while maintaining mix stability (reduced segregation/bleeding).

Adhesion + cohesion

Improves bond to primed concrete and other mineral substrates; helps resist shear and delamination.

Toughness

Supports flexural strength development and crack resistance—especially in thin-layer applications.

Available polymer chemistries can include (depending on lane) redispersible polymer powder (RDP) grades or liquid polymer dispersions. The right choice depends on binder type, target open time, thickness range, and performance testing requirements.

Applications

Where this polymer additive is commonly specified in underlayment and leveling systems.

  • Cementitious self-leveling underlayments (SLU) for interior floors
  • Gypsum / anhydrite leveling compounds (system-dependent)
  • Smoothing compounds and feather-finish skim coats (where compatible)
  • Renovation and overlay systems (bond-critical applications)
  • Pump-applied leveling mixes (when rheology + stability are required)
Procurement tip
If you share your target standard/test method and substrate prep steps, we can propose a grade that’s closer to pass on the first lab run.

Formulation & processing guidance

Practical notes used by formulators when evaluating polymer grades for self-leveling systems.

Quality & documentation

Typical addition level

Polymer demand depends on binder and fillers, desired flexibility, and adhesion requirements. Many systems use low single-digit polymer levels (by binder) for powder grades, or comparable polymer solids for liquid grades. We confirm a recommended range on quotation based on your formula concept.

Note: Actual dosage is grade- and system-specific; lab validation is required.

Compatibility

Commonly used with Portland cement systems and, in selected cases, gypsum/anhydrite systems depending on overall formulation. Compatibility can be influenced by defoamers, cellulose ethers, retarders/accelerators, and superplasticizers.

Share your key admixtures so we can avoid negative interactions.

Mixing & dispersion

Good dispersion is critical for consistent flow and strength. For powders, ensure adequate dry blending and controlled water addition. For liquids, ensure uniform incorporation and consider antifoam requirements to control entrapped air.

We can suggest a lab mixing sequence based on your equipment.

Rheology balance

Polymer improves cohesion, but overall flow is a system property (polymer + water reducer + thickener + fillers). For pumpable mixes, stability against segregation is as important as initial flow.

Film formation / curing

Polymer film formation supports adhesion and toughness. Temperature, humidity, and airflow affect curing behavior, particularly for fast-track applications and thin layers.

Tell us your site conditions and cure schedule assumptions.

Substrate preparation

Bond performance depends heavily on primer selection, surface strength, and moisture conditions. Polymer helps, but does not replace correct substrate preparation and priming procedures.

Typical specifications & supply formats

We supply the appropriate polymer grade per your system. Confirm exact values on quotation and COA.

Commercial & supply details

Atlas Global Trading Co. coordinates supply for construction chemical inputs with repeat procurement in mind. We can support sampling, documentation alignment, and export-ready packaging for regional distribution or direct project demand.

Quoting approach

We quote against your binder system, target performance, and packaging/destination. Where multiple grades could fit, we propose a “primary” and an “alternate” option to reduce qualification time.

MOQ & sampling

MOQ varies by grade and lane (bagged powder vs liquid drums/IBC). Samples may be available for qualification depending on supply conditions. Share your lab plan and required sample size.

Lead time & Incoterms

Lead time depends on origin, packaging, and volume. We can align Incoterms (EXW/FCA/FOB/CFR/CIF where applicable) based on your logistics setup.

For repeat buys
Ask for a supply plan (monthly call-off, safety stock logic, and packaging standardization) to reduce variability and simplify receiving.

Storage, handling & quality notes

General handling guidance. Always follow the SDS for the specific grade supplied.

Storage

Store sealed packaging in a cool, dry area away from direct sunlight and moisture. For powders, protect from humidity to prevent caking. For liquids, protect from extreme temperatures.

Shelf life

Typical shelf life is grade-dependent and confirmed on packaging and documentation. If you share your warehousing conditions, we can recommend packaging and handling practices.

Quality checks

Receiving teams often verify packaging integrity, batch identifiers, and basic appearance checks. COA alignment can be included for controlled procurement lanes.

Important: This product is supplied for industrial/professional use. Application performance depends on the full formulation, substrate preparation, primer selection, and site conditions.

FAQ

Fast answers for procurement and technical alignment.

Powder or liquid—what should I choose?

Powder grades integrate well into dry-mix SLU products and simplify transport. Liquid grades may suit certain wet systems or specialty mixes. The choice depends on your production method, water reducers, and target performance.

Will this improve adhesion to difficult substrates?

Polymer can significantly improve adhesion within a properly designed and primed system. Substrate preparation and primer compatibility remain critical, especially for low-porosity surfaces.

Can you help us match an existing benchmark?

Yes. If you provide the benchmark grade (or its key properties) and your test targets, we can propose comparable grades and a qualification path.

To speed up
Include your binder type, target thickness (mm), flow test method, and adhesion requirement in the RFQ. That’s usually enough to propose the correct grade range.
