Z86 Siliceous Earth CAS 61790‑53‑2 is high‑purity finely milled natural siliceous earth with narrow particle‑size distribution. It acts as multi‑functional extender in printing ink and overprint varnish. Its porous particle structure optimizes thixotropy and suspension stability, reduces pigment settlement during storage. Meanwhile it boosts rub‑resistance and delivers controlled matte effect, avoids printing surface stickiness, widely applied for offset, gravure, flexo printing ink and overprin

Product Detail

Overview

Our Z86 Siliceous Earth CAS 61790‑53‑2 is processed from high‑grade diatomite ore through deep purification, ultra‑fine grinding and multi‑stage classification. This special filler is custom‑developed for printing ink and overprint varnish. Strict control over oversized particles prevents printing plate abrasion and dot defect. It cooperates with pigments and binders to stabilize ink rheological behaviour and upgrade finished printed surface quality.

Key Features

Excellent anti‑settling performance, effectively inhibit pigment and filler sedimentation during ink storage.
Adjust ink thixotropy and flow property, improve transfer performance on high‑speed printing equipment.
Enhance rub resistance and anti‑blocking property of printed film, prevent printed surface sticking.
Provide uniform matting effect for overprint varnish, acquire stable matte and satin printed appearance.
Fine and controlled particle size, reduce abrasion to printing plate and anilox roller.
Good compatibility with offset, gravure, flexo ink resin systems, low impurity minimize side effects.

Main Applications

Offset printing ink functional extender
Gravure and flexographic printing ink filler
Water‑based and solvent‑based overprint varnish
Matte printing varnish for packaging and publication printing
High‑speed printing system requiring anti‑blocking and rub‑resistance improvement

Usage Recommendation

Typical adding dosage: 3‑15 % by weight, adjust according to ink type, matting requirement and printing speed.
Add in high‑speed dispersion stage, ensure full de‑agglomeration to avoid printing dot defects.
Suggest sieve inspection for incoming material to remove occasional coarse impurities.
Keep raw material dry; excess moisture will cause foaming and printing faults in water‑borne ink.
Complete lab print simulation test before mass production to verify transfer effect and anti‑blocking performance.

Storage & Package

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