Ultrapure Silica Filler, Micro Silicon Powder for Paint or Coatings

Basic introductions:

Silica micropowder is made from high purity natural quartz and produced by means of particular cleaning and ironless ultrafinegrinding. Ultrapure silica filler for paint has functions of thickening, thixotropic, reinforcing.

Specifications:

Appearance:         white powder

SiO₂:                 99.5%

Average particle size:         1.5-30μm

Fe 2 O 3 :            ≤ 0.03%

Al 2 O 3 :             ≤ 0.12%

Oil absorption :        14-23 g/100g

Heating loss%:        ≤ 0.3%

Specific surface area:   4800-38000 cm 3 / cc

Fineness (mesh):     1250-8000

Features:

1. Good chemical stability, acid-alkali resistance

2. Low oil absorption, low viscosity, good dispersion and fluidity

3. Heat-resisting, good insulation

4. Abrasion resistance, scratch resistance

Application:

Powder coating, anti-corrosion coating, coil coating, wood coating, insulated paint, mixed paint, interior and exterior decorative paint.

Note:

Silica micropowder is easy to settle in the diluted paint due to its large density. Thereby measures of anti-settling should be taken.

Packaging:

Packaging: PP woven bag with inner film bag.

Net weight: 25kg / bag

Storage: To avoid damp and soiled, the packaging bag should be closely tied after use.

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.
