Product Introduction
This product adopts environmentally friendly water-based aliphatic polyurethane dispersion water-based HDI curing, environmentally friendly pigments, and water-based polymer additives. Ultra low VOC content, low odor, excellent resistance and hardness, easy to hit, high filling, high corrosion resistance, and good substrate adhesion.Product Application
Used as primer for metal parts, automotive locomotives, construction machinery, mechanical decoration, vehicle components, etc.Instructions
1. Surface treatment: Before painting, the surface of the substrate should be cleaned of oil stains, rust, and other dirt to ensure that the substrate is clean, dry, and free of pollution. Polish the welding slag on the metal surface until it is smooth, sandblasting to Sa2.5 level or manually polishing to St2 level. 2. Dilution ratio: Before construction, mix the original paint evenly, add curing agent and purified water in proportion, and stir while adding. After mixing evenly, let it sit for 3-5 minutes for construction. The mixed paint should be used up in about 4 hours. Please request detailed construction instructions from our company for the specific construction ratio. 3. Construction method and tools: This product is recommended to be sprayed for construction, and can be baked at 60-80 ° C. Before baking, let it stand and level for 5 minutes. Suggested construction temperature ≥ 5 ° C; Humidity ≤ 75% R.C.Storage and transportation
