Aliphatic recoatable polyurethane topcoat
Aliphatic recoatable polyurethane topcoat is a two-component coating composed of hydroxyl resin, aliphatic isocyanate, pigment filler, various additives, etc. It has excellent weather resistance, excellent gloss and color retention, hard paint film and good gloss. No chalking, no yellowing, good decoration, good oil resistance and solvent resistance, recoating, good construction performance.
Rear supporting:
Zinc-rich primer, epoxy primer, epoxy intermediate coat, etc.
The surface must be dry and clean before construction, free of any contaminants (grease, zinc salts, etc.)
Uses:
Offshore platform facilities, railways, highway bridge steel structures, mechanical equipment anti-corrosion decoration, large vehicles, train carriages, locomotive heads, machine tools, instruments, meters, etc.
ACRYLIC POLYURETHANE TOPCOAT
SCOPE OF APPLICATION
High-performance coatings for steel structure surfaces of mechanical equipment surfaces, instrumentation, ships, machine tools, highways, bridges, and municipal engineering

Rear supporting: zinc-rich primer, epoxy primer, epoxy intermediate coat, etc.
The surface must be dry and clean before construction, free of any contaminants (grease, zinc salts, etc.)
Construction conditions: The temperature of the substrate must be higher than 3°C to prevent condensation, and the relative humidity should not be greater than 80% when working outdoors.
Mixing: Component A should be stirred evenly first, and then component B (curing agent) should be added to mix, and stirred thoroughly.
Dilution: Components A and B are mixed evenly, and after fully curing, an appropriate amount of supporting diluent can be added, stirred evenly, and adjusted to the construction viscosity.
The construction site should have a good ventilation environment to prevent the inhalation of solvent gases and paint mist. The product should be
kept away from the heat source, and smoking is strictly prohibited on the construction site.
Eyes: If paint splashes into your eyes, rinse immediately with plenty of water and seek medical attention.
Skin: If the skin is stained with paint, rinse with soap and water or use an appropriate industrial cleaner, do not use large amounts of solvents or thinners.
Inhalation or inhalation: due to inhalation of a large amount of solvent gas or paint mist, it should be immediately moved to a fresh place of air, loosen the collar, and let it gradually recover. f ingested with paint, seek medical attention immediately.
Storage: It must be stored in accordance with national regulations, the environment is dry, ventilated and cool, and high temperature and far away from the fire source.
Storage validity: 12 months, after which it should be used after passing the inspection
Packing: Part A: 20kg, Part B: 4kg
