APPLICATION GUIDE
Matting Agent for Floor Coatings
Durable matte and satin finishes for industrial floors, sports surfaces, and decorative flooring — engineered for abrasion resistance and chemical durability under heavy foot traffic.
The Challenge of Matte Finishes Under Foot Traffic
Floor coatings operate in the harshest conditions of any architectural surface. They must maintain consistent gloss levels after thousands of walking cycles, resist chemical spills, cleaning agents, and abrasive particles tracked in from outdoors, while providing a safe, non-slip surface. Matting agents in floor systems must contribute to — not detract from — this mechanical durability.
GMATT 300 Series is purpose-built for high-wear floor applications, combining matting efficiency with structural reinforcement of the cured film.
Key Performance Requirements
- Abrasion ResistanceFloor coatings must withstand Taber abrasion testing (ASTM D4060) at <30 mg weight loss per 1000 cycles. GMATT 300 Series acts as a micro-reinforcing filler that improves abrasion resistance by 20–30% versus unmatted systems.
- Chemical ResistanceIndustrial and commercial floors face regular exposure to cleaning agents, oils, and chemicals. GMATT silica is chemically inert and does not swell, dissolve, or contribute to chemical breakthrough in the film.
- Anti-Slip Surface TextureGMATT 300 Series creates controlled surface micro-roughness that contributes to R-value slip resistance ratings (DIN 51130 R10–R11) without requiring separate aggregate additions.
- UV-Cure Compatibility for Sports FlooringUV-cured coatings on wood gymnasium floors and PVC court surfaces require matting agents that do not inhibit radical cure. GMATT UV Series is optimized for these applications.
- Anti-Sedimentation in Water-Based SystemsWaterborne floor finishes require matting agents that resist hard settling during storage. GMATT WB Series incorporates wax-treated surfaces for easy re-dispersion after standing.
Product Selection Guide
| Application | Recommended Grade | Typical Dosage | Key Benefit |
|---|---|---|---|
| Industrial epoxy / PU floor | GMATT 300 Series | 3.0–6.0% | Abrasion resistance, chemical durability |
| Waterborne wood floor finish | GMATT WB Series | 2.0–4.0% | Anti-settling, consistent sheen |
| UV-cured sports floor (wood/PVC) | GMATT UV Series | 2.5–5.0% | No cure inhibition, hard surface |
| Decorative self-leveling floor | GMATT 200 Series | 2.0–4.0% | Uniform flatting, aesthetics |
FORMULATOR TIP
In two-component polyurethane floor systems, add GMATT 300 to the base component and mix thoroughly before adding the isocyanate hardener. Adding the matting agent after pot-life has begun reduces dispersion quality and can cause gloss uniformity issues in the final film.
Frequently Asked Questions
How do I balance matting efficiency with abrasion resistance?
GMATT 300 Series uses a controlled pore structure and surface treatment that provides matting efficiency while reinforcing the film matrix. The silica particles act as micro-fillers that improve Taber abrasion resistance by 20–30% versus unmatted references at equivalent gloss levels.
Will matting agents reduce the anti-slip rating of floor coatings?
GMATT 300 Series maintains or improves R-value ratings (DIN 51130) by increasing surface micro-roughness. The controlled particle projection at the film surface provides the texture needed for slip resistance without compromising film integrity.
Which GMATT grade is suitable for UV-cured sports flooring?
GMATT UV Series is the preferred choice for UV-cured wood or PVC sports flooring. It is compatible with acrylate chemistry, does not inhibit cure, and delivers consistent matte finish with the high abrasion resistance required for court and gym surfaces.
