Construction instructions:
Main agent: curing agent = 20:7.5, stir evenly, add 10-15% epoxy diluent, and apply by high-pressure airless spray, brush or roller.
Surface treatment:
The steel surface treatment is carried out in accordance with the national standard "Surface rust grade and rust removal grade of steel before painting" GB8923-88. Sandblasting rust removal reaches the national standard Sa2.5 grade, and manual rust removal reaches St3 grade.
Notes:
1. The paint should be stored in a low temperature, ventilated and dry place; away from fire and heat sources; the shelf life is one year in a cool and dry place.
2. The above information is written based on actual testing and usage experience of our company's technical personnel and can be used as a construction guide. However, due to differences in coating environments and supporting solutions, it is recommended that users conduct preliminary experiments and tests based on actual needs and uses before confirming use. Our company only guarantees the quality and stability of this product itself.
