PU Glue For Color Steel Sandwich Panel

Polyurethane color steel plate adhesive, composed of polyurethane resin, fillers, curing agents, and possibly solvents, excels in bonding, weather resistance, chemical resistance, and structural support. Ideal for construction, industrial equipment, furniture, and automotive applications, it’s also eco-friendly due to solvent-free options.


The glue is superior in performance and operation. By adopting solidifying way of micro moisture in air and cohered surface, the glue line is no-dissolving and no-melting. Therefore it has been extensively used in metal plates such as color steel plates, galvanized plates and aluminium plates as well as inorganic boards such as paper gypsum planks, calcium silicate boards, glass magnesium boards, medium density board and ternary plates. In addition, it can also applied to fireproof material (rockwool, glass fiber, perlite, aluminosilicate fiber felt), heat insulating material (EPS FWB foams,XPS, rigid PU foams), sound-proof material(paper honeycomb, aluminum honeycomb) and finishing material(melamine board).
