Almost all plastics can be fluoridized, after fluoridation, the surface polarity of the injection molding can be improved to enhance hydrophilia. Such technique has stable reaction and convenient operation, and it is a rare cutting-edge technology.

　　Such kind of technique is used for surface treatment of automotive trim, polymer sticking technology, building materials and other field, especially, in the spraying technology of water-based paint, the application of such technique can greatly improve adhesive force, uniformity and reduce composite cost.
