    摘要： Disclosed herein are coated substrates comprising a coating layer and an adhesive formed on at least a portion of the coating layer. The coating layer may be deposited from a powder coating composition and comprises a dielectric strength of at least 50 kV/mm measured according to ASTM D149-09 (voltage limit 12.0 kV DC, Imax Limit 0.1 mA, 19 sec ramp, 20 sec dwell, 2 sec fall) and a thermal conductivity of at least 0.3 W/K·m measured according to ASTM D5470 (steady-state methods). The adhesive may be formed from an adhesive composition and comprises a thermal conductivity of at least 1.0 W/K·m measured according to ASTM D5470. Also disclosed herein are systems for coating substrates. Also disclosed are methods of coating a substrate.

    摘要： The present invention provides a multi-phase structured UV-curable powder coating resin and a preparation method thereof, comprising (1) obtaining an emulsion of a liquid UV resin by heating the liquid UV resin and an emulsifier, dispersing, and adding deionized water for emulsification; (2) melting and dispersing a solid UV resin, a phase change agent, an emulsifier, and deionized water; adding the emulsion of the liquid UV resin with stirring to thoroughly mix; temperature is lowered during the stirring to obtain a suspension; (3) press filtering the suspension of the UV-curable powder coating resin to obtain a filter cake; (4) drying and classifying the filter cake to obtain the multi-phase structured UV-curable powder coating resin. The multi-phase structured UV-curable powder coating resin is prepared from the aforementioned method. The present disclosure has the properties of both the liquid UV resin and the solid UV resin and can be sprayed as a powder coating. It can be used in a wide range of applications and is environmentally friendly.
