Raw material ratio
The waterproof coating of enameled wire paint is composed of the following components in weight percentage: polyurethane modified acrylate photosensitive resin 20-45%, polyurethane resin 20-60%, waterproof fluorocarbon functional diluent 14-30%, photosensitive crosslinking agent 5-10% % diluent and 1-5% photoinitiator. The light-curing waterproof coating is prepared by mixing and pre-polymerizing the components at 20-25°C.

Advantage
The light-curing waterproof coating for enameled wire surface treatment can meet the breakdown resistance and waterproof requirements: the breakdown voltage is ≥ 3.5kv, the coating will not produce pores when it is stretched underwater, bent or kneaded underwater, and there are no pinholes in normal salt water. ≤1, use light curing method to solve the problem The existing enameled wire paint has the characteristics of high energy consumption and great environmental hazards, which brings convenience and practical benefits to the production of enterprises. 

Water-proof coating has efficient hydrophobic function.

How to make water-proof coating for enameled wire?
(1) polyurethane-modified polyacrylate photosensitive resin and urethane resin is got in proportion, through high-speed stirring 10-20min under normal temperature;
(2) water-repellancy fluorine carbon function thinner, photosensitive bridging property thinner is slowly added to, in reactor, stirring until mixing;
(3) slowly add light-initiated dose under stirring, stir even sealing and obtain photo-cured coating.
Preferably, described preparation method carries out at 20-25 DEG C.
