Z86 High Purity Filler CAS 61790-53-2 for Wood Coating and Clear Varnish
Z86 High Purity Filler CAS 61790‑53‑2 is high‑purity fine‑ground natural siliceous earth filler with strictly controlled oversize particles and low colored impurities. It is specially applied in wood coating and clear varnish formulations. It achieves soft and uniform matte appearance without obvious haze loss of transparency, enhances scratch resistance and anti‑settling performance of varnish, optimizes surface touch feeling of furniture paint film, widely used for furniture, cabinet and woode
Overview
Our Z86 High Purity Filler CAS 61790‑53‑2 is produced from high‑grade diatomite ore through deep purification, fine grinding and multi‑stage precise classification. Strict removal of coarse grains and chromatic impurities minimizes negative influence on varnish transparency. This grade is customized for wood coating and clear varnish, balancing matting property, transparency and film mechanical performance for furniture finishing.
Key Features
- High purity and low colored impurities, less adverse impact on transparency of clear varnish.
- Uniform soft matting effect, obtain elegant matte‑satin finish for wood surface.
- Improve scratch resistance and anti‑mar performance of dry wood paint film.
- Enhance suspension stability of varnish, reduce filler precipitation during storage.
- Good dispersion in solvent‑borne and water‑borne wood coating systems, low agglomeration tendency.
- Moderate oil absorption value, rational control varnish viscosity and construction workability.
Main Applications
- Furniture wood clear varnish and satin finish coating
- Cabinet wood topcoat, wooden craft transparent finishing paint
- Water‑based wood lacquer, solvent‑borne polyurethane wood coating
- Interior wood decorative matte coating
- Transparent finishing formula requiring soft matte appearance
Usage Recommendation
- Recommended dosage: 3‑18 % by weight, adjust matting degree according to gloss target.
- Add under high‑speed dispersion, guarantee sufficient shear to avoid agglomeration which causes white spot defect.
- Incoming sieve inspection is suggested to exclude occasional coarse impurity.
- Keep raw material dry; excessive moisture will produce film defects in water‑borne wood varnish.
- Conduct small‑scale lab test on transparency, gloss and storage stability before mass production.
Storage & Package
- Store in dry and dust‑proof warehouse, keep bags tightly sealed against moisture absorption.
- Standard package: 25kg woven bag with inner PE liner.
