Vacuum Coating This product is the protection of polymer materials. Through a unique vacuum vapor deposition can be completely within the device, the bottom, around the formation of no stress, no pinholes, thickness of transparent insulating coating, such coating has excellent electrical insulation, isolation protection, is the most effective moisture, fog, anti-acid, salt spray put quality protective coating. Deposited film features: Drainage, gas protective excellent acid and alkali resistance, corrosion resistance superior to anti-dissolution, excellent electrical insulation, barrier effects with unparalleled, ultra-low temperature mechanical properties, excellent flexibility, low frost resistance -200 degrees, little gas distribution, stress-free coating transparent, uniform, various shapes can be coated to the surface, including edges and corners, and cracks.
