A primer or undercoat is a preparatory coating put on materials before painting. Priming ensures better adhesion of paint to the surface, increases paint durability, and provides additional protection for the material being painted, primer consists of 20%-30% synthetic resin, 60%-80% solvent and 2%-5% additive agent. Primer paint used for painting all kind of metal and prevent metal surface from oxides. Primer is a paint product that allows finishing paint to adhere much better than if it were used alone. For this purpose, primer is designed to adhere to surfaces and to form a binding layer that is better prepared to receive the paint. Because primers do not need to be engineered to form a durable finished surface, they can instead be engineered to have improved filling and binding properties with the material underneath. Primer can be used for wood, metal and plastic surfaces. Primers can be made easily using regular raw materials. All formulas are avaliable online at buyformula.net
