Functional Siliceous Earth Filler Type N85 CAS 61790‑53‑2 is high‑purity natural siliceous earth filler with D50 3.0μm, produced by milling and multi‑stage particle‑size classification. It possesses moderate oil‑absorption capacity and semi‑reinforcing effect. This general‑grade mineral extender can be applied for coating, rubber elastomer, sealant‑adhesive and building putty. It optimizes product hardness, rheological behaviour and dimensional stability, effectively reducing raw‑material cost f

Product Detail

Overview

Our Type N85 Functional Siliceous Earth Filler CAS 61790‑53‑2 is refined from premium natural diatomite ore through impurity removal, fine grinding and strict classification to stable D50 3.0μm. As cost‑effective general‑purpose grade, it balances processing performance and mechanical improvement. Suitable for mass production scenarios of coating, rubber, sealant and construction materials, it helps enterprises realize formula cost control while keeping stable product quality.

Key Features

Stable D50 3.0μm particle size, balanced particle‑size distribution, wide formula adaptability.
Semi‑reinforcing property, improve hardness, rigidity and dimensional stability of rubber and coating film.
Moderate oil absorption value, well‑balanced viscosity control for paint, sealant and rubber compound.
Good matting effect for coating systems, adjust gloss without obvious negative influence on film performance.
Excellent dispersion in water‑borne, solvent‑borne paint, rubber kneading and sealant stirring systems.
Low soluble impurity, chemically inert, compatible with most resins, rubber auxiliaries and construction additives.

Main Applications

Interior and exterior architectural emulsion paint, general industrial coating
Molded rubber parts, gaskets, O‑rings and various rubber compound
Construction sealant, adhesive and building sealant system
Thermoplastic and rubber extrusion products
Putty, filler compound and other building material formulations

Usage Recommendation

Typical addition range: 6‑30 % by weight, adjust according to different application systems and performance targets.
For coating: add at high‑speed dispersion stage, ensure sufficient shearing to avoid particle agglomeration.
For rubber and sealant: feed in kneader or internal mixer for full wetting and homogenization.
Keep raw material fully dry; excessive moisture may cause bubbles and surface defects in finished goods.
Carry out laboratory small‑batch trial verification before formal mass production.

Storage & Package

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