GP® BKR-2620 coating resin is a solid, heat-reactive, modified phenolic resin. It can be used with a wide selection of solvents and is compatible with plasticizers and polyvinyl butyral resins. Films made with unplasticized GP BKR-2620 resin have greater flexibility than those made with other unmodified phenolic resin baking solutions.
