Large Pore Silica Matting Agent, Macropore Silica Gel Matting Agent

Brief Introduction:

Large pore silica gel matting agent is high purity, porosity, synthetic and amorphous, capable to control particle size precisely. The product has better transparency and dispersibility than other matting agent by method of precipitation. Silica matting agent has higher extinction efficiency owe to higher porosity and narrower particle size distribution. KT020 is very popular used as alternatives of Degussa OK520.

Main Features:

1. Higher extinction efficiency

Compare with other silica matte powder, this series have higher extinction efficiency owe to higher porosity and narrower size distribution.

2. Super dispersity

The powder has super dispersity that could be added into any process of coating production. It also can be added to final paint to adjust gloss. Powder through organic wax treatment has better redispersibility.

3. Perfect performance of suspension

Using the newest technique of wax surface treatment, the product has excellent suspension property. There’s no hard sedimentation even after long storage in the low viscosity varnish.

4. Excellent paint film

The organic surface-treated matting agent is basically compatible with all solvent-based paints without re-coating or adhesion problems, nor reduce the transparency of paint film. The paint is good feel and smoothness, besides the anti-pollution and anti-chemical properties are improved.

Applications:

Water-based paint, furniture paint, wood paint, decorative paint, PU curable coating, floor paint, powder coating. Ideal matting agent should be selected according to the dry film thickness of paint systems and requirements on the surface properties of paint film.

Our featured filler:

1. Matting agent replace Degussa OK520: high suspensibility, high dispersibility, widely used in water-borne coatings, two-component polyurethane coatings, wood coatings, transparent lacquer, UV coating

2. Transparent filler: anhydrous, paint film without blue-ray, very high transparent, the best reinforcing filler for PE, PU, water base wood paint, clear lacquer;

3. Calcium silicate reinforcing filler: great hiding powder, very high whiteness, good weatherability, alternatives of DuPont titanium dioxide powder R902;

4. High purity crystalline quartz filler: very high hardness, high purity, superfine, high transparent, used in matt paint, wood lacquer, PU, NC,UV, water based paints;

5. Micro silicon powder( silica filler): superfine, ultrapure, spherical, reinforcement, thixotropy, aging resistance filler for anti-corrosion coating, insulated paint, mixed paint, interior and exterior decorative paint;

6. White carbon: high dispersible precipitated silica, mainly used in rubber, tires, energy-saving tyre, shoes materials, similar to Zeosil;

7. A series of zinc stearate for coatings and plastics: for different demands on transparency, fineness, dispersibility, grinability, defoaming, waterproof, we will recommend the most suitable type;

We are Chinese supplier offers reinforcing filler for many industries, including coatings filler, plastic filler, paint filler, rubber filler, leather filler, silicon filler, stone filler, etc.
