Spray paint aluminum sheet types:
Spray paint aluminum sheet coating can be divided into polyester coated aluminium coil (PE) and fluorocarbon coated aluminium coil (PVDF). The polyester coating formed by repeated baking on the surface of aluminium sheet can form a continuous solid film with protective decorative properties. It is an anti-UV ultraviolet coating. Polyester resin is a polymer monomer with ester bond in the main chain. It is added with alkyd resin. Ultraviolet absorbent can be divided into sub-gloss and high gloss series according to gloss. It can give colorful aluminium articles rich color, and has good gloss and smoothness, as well as superior texture and feel, can also increase the level and three-dimensional sense. It can protect objects exposed to the atmosphere and attacked by ultraviolet radiation, wind blowing, rain, frost and snow. Because of the effects of temperature difference, freeze-thaw cycle, corrosive gases and microorganisms, the coating can play a protective role.
