Product Overview

 

Mattex® engineered kaolin is a fine particle-size kaolin with high brightness. It is easy to disperse and gives a low sheen with high opacity. It is thus commonly used for interior and exterior architectural coatings where matting is required. 

Mattex® PRO gives similar benefits to Mattex® but offers a very high level of scrub resistance as well, perfect for busy areas that endure frequent abrasion. 

See the brochures below for more information about what is possible with these additives. Our technical sales team are awaiting your enquiry.
