Powder coating base material. Find powder coatings on globalspec by specifications. Coatings made from polyvinylidene fluoride resin nch 2 cf 2 baking ch 2 cf 2 n pvdf as the base material or with metal aluminium powder as the colour material fluorocarbon matrix is chemically bonded by fluorine carbonization whole bond. The first consideration for coating objects besides metal is can it withstand the temperature.
The powder used for the process is a mixture of finely ground particles of pigment and resin which is sprayed onto a surface to be coated. Unlike conventional liquid paint which is delivered via an evaporating solvent powder coating is typically applied electrostatically and then cured under heat or with ultraviolet light. It is very important to have a clear understanding of the true composition of the surface of the part.
