Unlike the middle-wave and long-wave infrared, the wavelength short-wave has a strong penetration, straight into the paint, then the temperature of the body shell will be rised quickly with heat effect, the moisture of the coating volatilize from inside to outside quickly. In the same chemical frequency,due to the syntony,of the paint, which increase the prossibility of the cross-linked,and accelerate the curing of the layer. Therefore, the paint surface is gloss and fullness, and the mirror more  clear, coating adhesion is strong, and not easy to produce "orange peel, tearing" phenomenon, avoid rework, reduce costs and improve efficiency.
