Construction instructions:
Main agent: curing agent = 3:1, stir evenly, add 10-15% inorganic zinc-rich primer thinner, 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.
