PU Resin for Surface Coating (2016)
Our PU resin for surface coating is supplied in a variety of types. Therein, the BYD1308 type, BYD1318 type and BYD1348 type of products are mostly used as transfer adhesive or adhesives for bonding paper, aluminum, PET materials, surface varnish coating of transfer paper, flexible package of printing varnish, etc. It is also applied in polishing card paper.
The BYD1007 type and the BYD1403 type of PU resins are usually used for fabricating the quality surface coating of special paper, PET films and so on.
