Precipitated Silicon Dioxide (Si02) Silica Matting Agent HS Code: 281122 Use For PU Wood Coatings
Description
PU lacquers and PUR lacquers can be used on all surface materials. These are two component systems which require a pre-defined amount of activator to be added. Once mixed, the lacquers have pot-life. The solids content is between 25% to 65%. Polyurethane lacquers initially dry physically by means of solvent flashing off and then chemically from the reaction between the resin and the polyisocyante. The result is a hard, flexible film with excellent resistance to chemical and mechanical stress. Polyurethane lacquers are completely non-yellowing. Suitable for demanding areas such as kitchens, bathrooms, office furniture, restaurant furniture and table tops.
Paint Silica matting agent generally used for PU wood coating. Silica Matting Agent reduce the gloss of a variety of products including coatings, paints, inks, lacquers, varnishes, while providing lower viscosity and better flow capability.
Characters
Highest matting efficiency
Surface smoothness and improvement in scratch resistance
Excellent transparency
Good Anti-sentiment.

COMPANY MOTTO
VISION
MISSION
Introduction
Our reputation as a key national supplier is built upon the foundation of quality and integrity. The company has independently researched, developed and manufactured several series products including Silica Matting Agent, Matt Hardener, Fumed Silica, Zinc Stearate and Alumina.
Our product development is guided by accurate market analysis. We have successively established R&D Centers of Matting Agent, Fumed Silica, Zinc Stearate, Matt Hardener, and Alumina.Application Research centers were also created for mediums such as paints, ink, textiles, leathers and new energy materials. These Modern facilities form the very core of our development system and are staffed by a professional taskforce of technical personnel. Their contributions have yielded environmental-friendly products such as the low oil absorption UV matting agent, a compound that was specifically designed to minimize the VOC emission of paints. These Products are the building blocks of eco-friendly alternative engry solutions. Their ability to protect leather and prevent the corrosion of metals make them idea for floor coating, glass paint, and the making of woodenware.
Quanxu Technology firmly believes that technological advancement is the precursor for market performance. We have established major distribution centers in one overseas location and 3 domestic regions.
Product quality has always been at the very top of our priorities. Over the years, we have imported a number of advanced testing instuments enhanced quality control and inspection. Quanxu operates in strict adherence with all relevant safely standards. Our export products are approved by international recognized standards such as SGS and ROHS.
More than a decade of groundwork has allowed us to penetrate overseas markets in regions including Europe, the Middle East, South America, Southease Asia, Africa, Etc. We have established a long-term cooperative partnerships with international chemical mega-corporations such as Valspar and AKZONOBEL.
Through sustained growth and expansion, Quanxu Technology strives to become a world-leading supplier of chemical materials. With quality and integrity, we will create an enterprise that can withstand the test of time!!
