Product Overview

Diatomite Powder Filler CAS 61790‑53‑2 for Matting Agent in Paint and Coating

Paint and coating production needs cost‑effective matting fillers to adjust surface gloss of finished film. This diatomite powder filler relies on its irregular porous particle morphology to achieve physical matting effect. When dispersed evenly in coating system, particles protrude slightly on coating surface after film forming to reduce surface reflectivity, realizing low‑gloss and matte finish. Meanwhile it optimizes mechanical performance of coating film, ideal alternative for partial synthetic matting agent.

Key Features
