Eva Bond exterior protective shield for new buildings and renovation applications consists of a polyethylene core and 2 Aluminium skins each of 0.5 mm/0.25 mm thick.
At EVA BOND we are using online laminator and catalytic fusion process. Eva Bond consists of coated Aluminium skin. The catalytic fusion process guarantees each panel has high quality of durable coating on the top with minimum thickness of 25 microns.
Eva Bond with its standard has excellent robustness against industrial pollution & ability to survive in any extreme weather conditions. |
