RTM300B Type PUR hot melt Glue Laminating Machine
(in this photo, the glue melting system was old type, we had changed into new one.)
1. Performance and Applications:
◎ This machine is used for PUR hotmelt glue laminating , the PUR hotmelt glue has good and reliable adhesion and also it is environmental protection without any solvent chemical. But if the surface of PVC profile has more wax when extruded, it’s better to use primer to cleaning the surface of PVC profiles, then the adhesion will be more better;
◎ It is used to laminating PVC decorative film rolls, wood veneer, decorative paper and other decorative film rolls on the surface of various profiles within 300mm wide;
◎ The decorated profiles like PVC/UPVC window profiles, WPC/PVC foam door frames, MDF profiles, aluminum window profiles and etc;
