whats is the difference between the two types?and which one is better for corrosion resistance and scratching ?Whats the difference between baked enamel and polyester paint?
Baked Enamels are generally an economical one-coat process where the top-coat is applied directly to the material; no primer is required. They are primarily used for long term indoor applications. Baked enamel coatings are much harder and more wear resistant, they are not as resistant to corrosion and the elements.
The term polyester signifies a particular paint resin. Polyester resins can be modified with other resins to meet specific performance requirements. Paints containing polyester resin can be classified as good quality paints. When the best quality paint is specified then an epoxy resin is usually selected.
Polyester type coatings will meet most general purpose requirements. Although epoxy coatings will perform in hostile environments with excellent corrosion and chemical resistance epoxy coatings do have a few drawbacks, poor resistance to UV ultraviolet exposure resulting in oxidation or chalking. Also, the cost of epoxy coatings compared to polyester can range from 10% to 50% higher.Whats the difference between baked enamel and polyester paint?
