Matting Agent For Coatings
Description
It is a synthetic amorphous silica appearing as white powder. It is a micronized precipitated silica matting agent for both solvent-based and waterbome system. Optimal matting efficiency is achieved by using silica with high pore volume and by fine control of the particle size and particle size distribution. It provides a superior matting and flatting, excellent coating appearance and transparency, cost efficient, effective anti-settling agent and easy dispersion, smooth, abrasion resistant films of high surface quality. These efficient matting agent are suitable for unpigmented and pigmented systems. It mainly used for wood coating, decorative coating, industrial coating, plastic coating, coil coating and ink.
Characters
1, High Matting Efficiency: As this high-grade matt powder improves its porosity to 1.8-2.0 and decreases the distribution of micropores and ultra-large pore, the distribution of pores is more symmetrical and greatly improves the efficiency of delusterant; the diameter is narrower so as to reduce the negative influence of small granules on the effect.
2,Excellent Transparency: The purity of SiO2 in these products reaches to 99.3%,and special method is adopted for surface treatment so that its refraction index reaches 1.47,being close to that of colophony,i.e. 1.40~1.60,which greatly improves its transparency in coating film and avoid the low-grade matt powder's problem of turning white and blue on the surface.
3, Easy to Disperse: Advanced rubbing technology makes narrower distribution of diameter of granules, so that matting agent can be easily added in any production procedure and can be easily dispersed, which saves the processing time.
4, Excellent Hand-feeling: These silicas have minimal effect on the mechanical properties, allowing
development of smooth films with excellent hand-feel, scratch resistance and stain resistance.
5, Excellent Suspension Performance: This products have good anti-settling, suspension is good, no
precipitation.

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!!
