Dar-Tech Portaryte

Portaryte® 010 is the naturally occurring form of barium sulfate (BaS04). It has a high specific gravity (4.5) and very low solubility. The Portaryte® natural baryte range delivers a variety of benefits, from improving UV and chemical resistance in coatings to increasing soundproofing in plastics and enhancing friction in brake linings.

Portaryte® B10 is produced from carefully selected, very white, naturally occurring baryte. The standardized quality of 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 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.

Dar-Tech Portaryte® B3 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.

Dar-Tech Portaryte® C15 is a natural barium sulfate that comes without any residual salts when compared to precipitated grades. This product is closely monitored, and the particle size is kept within a narrow variation. In addition, this natural baryte is easier to disperse than precipitated grades.

Dar-Tech Portaryte® D15 is produced from carefully selected, naturally occurring off-white baryte. Dar-Tech Portaryte® D is successfully used in applications where excellent chemical inertness is required but high brightness and consistent color are less important, e.g., primers, sealants, and adhesives. The exceptionally high density of baryte makes Dar-Tech Portaryte® D an economical filler of choice for sound deadening in automotive and domestic applications (e.g. sewer pipes). The quality of Dar-Tech Portaryte® D is guaranteed by 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.
