Aluminum plate grade sheet metal

Due to the low adhesion of metal materials such as stainless steel and galvanized sheet to topcoat and printing ink, direct spraying of topcoat can cause defects such as topcoat detachment. Therefore, Aluminium Checker Plate before spraying topcoat on metal panels, a layer of approximately 0.01mm thick epoxy zinc yellow primer needs to be sprayed. Generally, metal primers use two component epoxy coatings, also known as epoxy high-strength coatings. Mainly using modified epoxy resin as the main film-forming material, solvent-free modification is achieved using active diluent toughening agents. It endows the coating with good adhesion, excellent chemical stability and mechanical properties. It can not only combine the finish paint with the metal firmly, Aluminum Products but also enhance the corrosion resistance of the metal surface. Epoxy primer is generally sprayed twice, with the first coat thoroughly drying before proceeding with a second coat.
