Description

A kind of vinylformic acid transparent powder paint

Technical field

The present invention relates generally to a kind of coating, relates in particular to a kind of vinylformic acid transparent powder paint.

Background technology

Heat curable powder coating refers to usings thermosetting resin as filmogen, has added the solidifying agent of crosslinking reaction can form insoluble not molten quality hard coat after heating.Temperature high this coating can be not softening as thermoplastic coating more yet, and can only decompose.The resin adopted due to thermosetting powder coating(s) is the prepolymer that the polymerization degree is lower, molecular weight is lower, so the levelling property of coating is better, have ornamental preferably, and low-molecular-weight prepolymer is after solidifying, can form the macromole of cross-linked network, thereby coating have better preservative property and mechanical property.Therefore thermosetting powder coating(s) development is particularly rapid, and in order to improve the overall performance of conventional powder, by adding new compounded mix etc. to improve its performance, be necessary.
