POSHACO thermal and soundproof corrugated iron is composed of 3 layers of corrugated iron + PU + Alufil foil. Thanks to the advanced – modern Taiwan technology line and special adhesion properties of PU to the corrugated iron surface and PVC film or foil to form a unified, solid and absolutely flat block without any type of material. What glue can I get?
