Project Description
Aluminum Silicate (Al2siO3)
Advantages in Paint Production:
- Widely used in the manufacturing of paint, as a less expensive alternative to Titanium dioxide.
- Part of white pigment like Titanium dioxide (10%/ more) can be replaced without loss of opacity.
- Give faster surface & through-drying in products which also stand up better to abrasive treatment.
- Excellent substrates for high gloss finishes as they ensure good leveling out.
