Dar-Tech Portaryte® B4
- CAS Number
- 7727-43-7
- Chemical Name
- Barium sulfate
Dar-Tech Portaryte® B4 is produced from carefully selected, very white, naturally occurring baryte. The standardized quality of Dar-Tech Portaryte® is guaranteed by means of an ISO 9001-certified quality management plan. The chemical composition of the raw material and the finished product is closely monitored, and the particle size is kept within a narrow variation. Fine grades of Dar-Tech Portaryte® fillers have been specially developed for powder coating applications. They are successfully used as an alternative for fine synthetic blanc fixe in high-gloss applications.
