Functional Siliceous Earth Filler Type Z86 CAS 61790‑53‑2 is high‑purity natural siliceous earth filler with D50 2.1μm median particle size. Through precise crushing, classification and purification treatment, it features narrow particle size distribution, low coarse particle residue. Incorporated into coating formulations, it optimizes surface smoothness, enhances matting performance, improves anti‑settling and rheological behavior, minimizes surface defects, well‑suited for high surface‑qualit

Product Detail

Overview

Our Type Z86 Functional Siliceous Earth Filler CAS 61790‑53‑2 is processed from premium natural diatomite ore. Strict milling and multi‑stage classification achieve stable D50 2.1μm particle size and narrow particle distribution. Low impurity and few oversize grains make it specially developed for high‑surface‑quality coating. It works as multi‑functional extender filler to upgrade coating surface appearance while controlling formulation cost.

Key Features

Stable D50 2.1μm fine particle, narrow particle‑size distribution, effectively reduce coating surface grain defects.
Good matting performance, contribute uniform matte finish without sacrificing coating smoothness.
Improve suspension stability of paint slurry, reduce pigment and filler settling during storage.
Excellent dispersibility in both solvent‑borne and water‑borne coating systems, less agglomeration.
Moderate oil absorption value, help control coating viscosity and improve film forming property.
Low heavy‑metal content, stable chemical inertness, good compatibility with resins, pigments and common paint additives.

Main Applications

High surface quality industrial decorative coating
Water‑based architectural topcoat, solvent‑borne industrial finish
Anti‑corrosion intermediate paint and primer requiring fine surface
General high‑grade paint where smooth film appearance is critical
Coating systems demanding controlled matte effect

Usage Recommendation

Suggest dosage range: 5‑25 % by weight, adjust according to target gloss, surface requirement and resin system.
Add during high‑speed dispersion stage, sufficient shearing dispersion to guarantee full de‑agglomeration.
Sieve inspection is recommended for incoming material to avoid occasional coarse impurities.
Cooperate with other extenders such as calcium carbonate, talc for formula optimization.
Complete lab trial before mass production to verify surface performance and storage stability.

Storage & Package

Store in dry and ventilated warehouse, keep bags tightly sealed against moisture absorption.
Standard package: 25kg woven bag with inner PE liner.
