Product Description

STWD8027 polyaspartic abrasion resistance floor coating

Product descriptions
STWD8027 is a two-component material with aliphatic polyaspartic polyurea resin as the main film-forming material, with excellent corrosion resistance, color-change resistance and weather resistance. The product has high solid and low viscosity, good leveling, and meets the requirements of environmental protection; it has excellent workability, can be applied by any application method, and can be cured at low temperature 0 ° C in winter. The coating has excellent flexibility, wear resistance, impact resistance and chemical resistance. It is an ideal weather resistant and environment-friendly floor coating material.

Features and benefits
* high solids low density, with good leveling, the coating film is tough, dense, full light and bright colors
* high adhesive strength, good compatible with polyurethane, epoxy and other coating film.
* high hardness, good scratch resistance and stain resistance
* excellent abrasion resistance, impact resistance
* excellent anticorrosion property, resist to acid, alkali, salt and others.
* no discoloration, UV resistance, no yellowing, no powdering, aging resistance, with excellent weather resistance and gloss and color retention property
* can be applied directly to the surface of metal surface (DTM)
* this product is environmentally friendly and contains no benzene solvents and lead compounds

Product application scope

Flooring of city Park Plaza, electronic plant, mechanical factory, chemical plant, pharmaceutical, food and other industrial floors, as well as various outdoor yellowing resistant and wear-resistant floors.
