Factory Custom Light Load Small Yellow Helical Compression Die Mold Spring

(1) asphalt paint asphalt paint has good water resistance, moisture resistance, corrosion resistance, especially excellent acid resistance and good alkaline resistance. But adhesion, mechanical strength, decorative poor.
(2) Phenolic paint phenolic paint is divided into two kinds of primer and finish paint, phenolic primer adhesion is strong, good rust resistance, but the mechanical strength and gloss of the film is poor. Phenolic top paint film hard, good gloss, but poor weather resistance, easy to yellow film.
(3) Alkyd paint alkyd paint film tough, strong adhesion, good mechanical properties, excellent luster, good durability and has a certain oil resistance, insulation performance. Its disadvantage is the surface dry fast and stick to the hand for a long time, easy to wrinkle, water resistance, alkali resistance.
(4) Epoxy paint epoxy paint adhesion, high hardness, and good toughness, flexural resistance, impact resistance, hard and not brittle, water, acid, alkali and many organic solvents have excellent resistance, especially alkali resistance is more prominent. Its disadvantage is fast flour surface, solvent selectivity. Water-soluble epoxy paint is used for electrophoretic coating.
