Dar-Tech Portaryte® D80 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.
