Coating‑Grade Siliceous Earth Filler is refined mineral filler as direct replacement for Sillitin Z86. Incorporated into primer and matte topcoat formulations, this siliceous earth enhances hiding capacity of coating films, delivers consistent matting effect, and promotes uniform pigment dispersion. It also improves sandability of primer layer for industrial coating production.

Product Detail

Product Overview Coating‑Grade Siliceous Earth Filler (CAS 61790‑53‑2, Sillitin Z86 Equivalent) is specially refined siliceous earth mineral filler for industrial coating applications. During grinding and dispersion of coating slurry, fine mineral particles distribute evenly within resin matrix. The filler boosts dry‑film hiding power, produces stable matte surface effect, and assists pigment wetting to reduce pigment agglomeration. Furthermore, it optimizes primer sanding property, which is beneficial for subsequent top‑coating operations. This mineral filler is suitable for water‑based and solvent‑based primer, matte industrial topcoat and anti‑corrosion coating manufacturing.

Key Features ‑ Enhances hiding performance of primer and matte coating dry films ‑ Provides uniform matting effect for industrial coating surfaces ‑ Improves pigment wetting and restrains pigment agglomeration in coating slurry ‑ Optimizes sandability of primer layer for better inter‑coat adhesion ‑ Direct functional equivalent grade for Sillitin Z86 coating‑grade mineral filler

Typical Technical Properties ‑ Chemical Type: Refined natural siliceous earth mineral ‑ Appearance: Off‑white fine free‑flowing powder ‑ Particle Size: Refer to TDS ‑ Bulk Density: Refer to TDS ‑ Oil Absorption Value: Refer to TDS

Applications ‑ Industrial primer manufacturing: Functional mineral filler for anti‑corrosion base primer ‑ Matte topcoat formulation: Matting and hiding filler for interior and exterior industrial coatings ‑ Paint workshop: Auxiliary mineral raw material for solvent‑borne and water‑borne paint production ‑ Coating compounding plant: Mineral extender pigment for custom industrial coating formulas

Processing Recommendation Add the siliceous earth filler at the grinding and dispersion stage of paint production. Adjust dosage according to targeted hiding power and matte degree requirements. Guarantee sufficient grinding to realize homogeneous dispersion. Complete lab formulation trials before large‑scale paint manufacturing.

Storage & Handling Store in cool, dry warehouse and avoid moisture ingress. Reseal packaging after opening. Wear dust‑proof mask and protective gloves when handling fine mineral powder.
