| SILTEX 32 |
 |
A new, ultra-high performance extender pigment and filler for the coatings and polymers industries.
SILTEX silica's unique lack of crystalline structure imparts improved optical, thermal and physical properties to many polymer systems that are not possible to obtain from naturally occurring silica sources.
SILTEX silica offers these unique advantages and properties:
1. Completely amorphous structure and purity imparts outstanding physical properties to many systems.
2. Low Refractive Index permits formulating translucent coatings with outstanding optical properties.
3. Chemical inertness and purity enhances the chemical resistance.
4. Low magnetic iron contamination and amorphous structure give outstanding electrical properties to resin systems.
5. Lowest thermal expansion of any mineral
6. Low moisture content and absorption enhances its uses in low moisture sensitive systems.
7. Extremely high specific resistance augments the electrical properties and dimensional stability of resin systems where moisture absorption and corrosion resistance are of prime importance. |
