Construction method of acrylic polyurethane finish paint for indoor and outdoor anti-corrosion of large steel structure

form:

The paint base is composed of hydroxyl resin, pigments, additives and organic solvents, and the aliphatic polyisocyanate is used as the curing agent.

characteristic:

After curing, the paint film is tough, with excellent adhesion, oil resistance, organic solvent resistance, and corrosion resistance to acid, alkali, salt fog, chemical atmosphere and other corrosive media. It has excellent low-temperature construction performance, good gloss, and strong decoration. Avoid contacting with water and alcohol solvents during storage and coating, otherwise the coating is easy to generate bubbles. This product is a recoatable polyurethane product.

Purpose:

It is suitable for anti-corrosion and decorative coating on the surface of chemical equipment, mechanical equipment, engineering equipment, electromechanical equipment, transportation equipment, outdoor pipelines, large steel structures, chemical storage tanks, and oil storage tanks in corrosive environments.

Drying time: surface drying ≤ 2h, solid drying ≤ 24h, fineness ≤ 4 μ m, adhesion ≤ Level 2

Flexibility ≤ 2mm Impact strength 30kg/cm

Proportion of blending weight:

Main paint: curing agent=6:1 (weight ratio)

Service life after mixing: 6 hours Density after mixing: 1.2~1.25 kg/L Flash point: 28 ℃

The thickness of each paint film is 40 microns for dry film and 95 microns for wet film

Theoretical paint consumption (i.e., without any loss) 0.12 jin/m2 (recorded as 40 microns of dry film)

Recommended coating number: 2~3

After an interval of 16 hours and more than 3 days, it shall be polished

The primer shall be dry and free of oil stain and dust

Construction environment:
