Polyvinylidene fluoride resin DY-1 is a kind of powdered polyvinylidene fluoride product. It can be mixed with acrylic resin and additives to form a bake type PVDF fluorocarbon coating with superior performance. Compared with other makes of PVDF, PVDF DY-1 is more suitable for preparing top coating and light colored coating in bake type PVDF fluorocarbon coatings.

The fluorocarbon coatings prepared using appropriate processes of mixing and spay processing with PVDF DY-1 as the raw material have good mechanical strength and toughness. The coatings have superb outdoor durability and weatherability under irradiation and severe weather conditions, etc. The coatings can be used for long period of time in wide range of temperatures and in the same time maintain the basic performance.
