Construction instructions:
Main agent: curing agent = 5:1, stir evenly, add 10-15% aliphatic polyurethane diluent, and apply by high-pressure airless spray, brush or roller.
Surface treatment:
Steel surface treatment is carried out in accordance with the national standard "Rust level and rust removal level of steel surface before painting" GB8923-88. Sandblasting rust removal reaches the national standard Sa2.5 level, and manual rust removal reaches St3 level.
Notes:
1. The paint should be placed in a low temperature, ventilated and dry place; away from fire and heat sources; stored in a cool and dry place with a shelf life of one year.
2. The above information is written based on the actual testing and use experience of our technical personnel, and can be used as a construction guide. However, due to the difference between the coating environment and the supporting plan, it is recommended that users conduct experiments and tests in advance according to actual needs and uses before confirming use. The company only guarantees the quality and stability of this product itself.
