Formed in 1970, PSG is a major supplier of aerospace and defence coatings, chemicals and adhesives throughout the world. The company was started by the Wood brothers from a single office in Godalming, Surrey, distributing industrial coatings to customers within the UK. In 1973 they moved to Haslemere, having gained ministry approval to expand into supplying the aircraft and defence coatings markets.  In 2016 the company moved from its home in Haslemere to a purpose-built facility in Bordon, Hampshire.

By 1992 PSG had achieved full BSi registration to BS5750. Today, PSG operates a Quality Management System which complies with the requirements of ISO AS9120 Rev A / BS EN 9120:2010 and ISO 9001:2008

The company is the official distributor for the Aerospace divisions of PPG, Sherwin-Williams, Henkel, ZipChem, Permagard, Pantheon Chemicals and Finishing Brands, and has recently broadened its product portfolio to include a comprehensive range of coatings, composite products and associated materials.

Whilst the company has grown considerably since its humble beginnings, PSG prides itself on being loyal to the original strong principles of its founders, placing great importance on service to its customers. PSG has thus built a solid reputation for excellent customer service alongside reliable technical expertise.
