Strathroy, Ontario, Canada – June 5, 2026 – The Sansin Corporation, a global leader in developing high-performance wood coatings announces the success of its Precision Coat KP-System on Accoya wood products. Following independent performance testing on Accoya and other wood substrates, Sansin’s coating system has demonstrated superior protection to competitors and over a decade of maintenance-free performance. Since 1986, Sansin has developed advanced wood coating technologies that excel in both film-forming and non-film-forming finishes. Today, Sansin announces warranty coverage of translucent coating products up to 15 years on vertical Accoya Radiata Pine when finished with Sansin’s recommended Precision Coat KP-system.

Product Performance & Testing 

The test compared substrate and performance of wood coatings. The wood samples were exposed at a 45˚angle on a south-west facing rack for maximum exposure at 51˚Latitude. After 10-years and three phases of testing, Sansin’s three-coat, Precision Coat translucent and opaque systems exhibited excellent performance on Accoya (See Figure 1 & 2). The Precision Coat KP-systems were evaluated in two colors: translucent – Medallion 1187 and opaque white – RAL 9010. These coatings were applied to wood substrates including Accoya, Meranti, Merbau, Pine, Spruce and Thermally Modified wood. 

“Long-term coating performance depends on coating technology, application expertise and substrate stability,” said John Alexander, Group Commercial Director. “Sansin’s investment in product innovation and long-term testing on Accoya reflects a shared commitment to performance and innovation. These results demonstrate the powerful synergy between Accoya’s exceptional dimensional stability and Sansin’s advanced coating systems, helping extend maintenance intervals while delivering low maintenance, long-lasting beauty and protection for exterior applications.”

Sansin’s water-borne coatings offer unparalleled wood protection for Accoya.

Sansin’s water-borne coatings utilize nanotechnology, combined with oils and resins in a way which works synergistically with wood to provide superior protection. These water-borne coatings penetrate deeply, forming a durable, breathable barrier that resists cracking, and peeling. Sansin’s low-VOC formula’s enhance Accoya’s natural beauty while providing enhanced, long-lasting protection.
