Product introduction: This product is a two-component anti-corrosion coating made of water-based acrylic resin or emulsion, modified isocyanate and other functional pigment fillers, mica, metal pigments and various additives.

Basic parameters:

1. Mixing ratio: main agent: curing agent = 5:1 (volume ratio).

2. Color: white, as specified.

3. Flash point: main agent: 18℃ curing agent: 30℃.

4. Volume solid content: 60±2%.

Application areas: Suitable for topcoat of chemical storage tanks, road and bridge facilities, and steel ship superstructures. It can also be used as a topcoat for decks and other steel structures.

Instructions for use:

1. Paint mixing ratio: main agent: curing agent = 5:1 (volume ratio).

2. Diluent: water.

3. Coating method: air spray, brush, roller. Easy to roll viscosity: 40-55 seconds, dilution: 0-10 volume ratio).

4. Construction conditions: Temperature: minimum 5℃ Humidity: maximum 85%

5. Drying time: ventilation conditions, temperature, humidity, film thickness, number of coats, etc. will affect the drying time accordingly.
