Microsilica High Purity Quartz

Basic introductions:
Microsilica High Purity Quartz is made from high purity natural quartz and produced by means of particular cleaning and ironless ultrafinegrinding.

Specifications:
Appearance: white powder
SiO 2 : 99.5%
Average particle size:20-35I m
Fe 2 O 3 : a 0.03%
Al 2 O 3 : a 0.12%
Oil absorption: 14-23 g/100g
Heating loss%: a 0.3%
Specific surface area : 4800-8000 cm 3 / cc
Fineness (mesh) : 1250-5000

Features:
1. Good chemical stability, acid-alkali resistance
2. Low oil absorption, low viscosity, good dispersion and fluidity
3. Heat-resisting, good insulation

Application:
Powder coating, anti-corrosion coating, coil coating, wood coating, 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.
