Knowledge Base
How do silica matting agents reduce gloss and how to select them?
Our silica matting agents reduce gloss by creating a Micro-Rough Surface that scatters light. Selection depends on film thickness: smaller particles (4 μm – 5 μm) for thin coatings and larger grades for high-build industrial systems.
What is the difference between organically treated and untreated silica?
Organically Treated grades are designed to prevent hard-cake sedimentation and improve scratch resistance, while untreated silica offers maximum matting efficiency and cost-effectiveness in waterborne systems.
How do matting agents perform in UV-Curable Systems?
For UV-Curable Systems, we provide specialized low-absorption silica that minimizes viscosity impact and avoids interfering with UV light transmittance, ensuring proper through-curing.
