Resolving the conflict between rapid curing and gloss control. Our specialized silica technology integrates into high-solid matrices without compromising cross-linking density.
Achieve a dead-matte finish without rheological instability. We utilize low oil absorption silica for high solid coatings, allowing for higher addition rates without causing viscosity drift or poor leveling in 100% UV systems.
Zero impact on throughput. Our nano-silica for photoinitiator systems is engineered with an optimized refractive index, ensuring maximum UV energy penetration for deep-layer curing at high line speeds.
Prevent surface defects. UV resins undergo volume contraction during polymerization; our silica particles feature a flexible gel-method porosity that adapts to film shrinkage, eliminating micro-cracking.
Beyond matting. As a powerful paint gloss reduction agent, our silica also acts as a structural reinforcer, dramatically increasing the scratch and taber abrasion resistance of heavy-traffic UV flooring.
UV Curing Optimization & Rheology Support.
In solvent-free systems, high oil absorption silica can rapidly "soak up" monomers, leading to an uncontrollable viscosity spike. The GMATT UV Series features controlled oil absorption to achieve high matting efficiency while maintaining a workable viscosity for roller and spray applications.
Standard fillers scatter light and block UV penetration. Our UV coating matting agent is designed to be transparent to UV radiation, ensuring that even at high dosages, the coating achieves full cross-linking density without reducing line speed.
UV resins contract significantly during curing. The unique internal pore structure of the GMATT UV Series acts as a stress-buffer, adapting to film shrinkage and preventing the internal tension that leads to micro-cracking and loss of adhesion.
By incorporating our specially treated silica, you create a reinforced composite surface. The GMATT UV Series increases the surface hardness and significantly improves taber abrasion resistance, making it ideal for heavy-traffic commercial flooring.
Yes. Our synthetic silica is chemically inert and high-purity (≥99.0% SiO₂). It does not interfere with photoinitiator stability or cause yellowing, making it compatible with both radical and cationic photoinitiator systems.
For 100% solid UV flooring and PVC topcoats, we recommend the GMATT UV Series (U700/U750/U800) for superior anti-settling and recoatability.
