Heavy Duty Coating

DNH-200F(E) Heat-resistant 200℃ top coat (silicone alkyd)

usage
Boiler, engine, stovepipe, radiator (heavy duty coating)

This paint is made by mixing silicone alkyd resin and pigments with excellent heat resistance and anti-corrosive properties. It is a heat-resistant top coat designed to withstand metal surface temperatures of up to 300℃. It has good adhesion and excellent bending resistance and impact resistance. It is widely used for new and repair painting in boilers and other structures that require heat resistance.

how to use

Surface treatment
1. Completely remove oil, moisture, sand, dust, and other foreign matter from the surface to be coated.
2. Sufficiently dry the surface to be coated.
3. After primer coating, clean up the welded areas (blackened and rusted areas) with a disc sander. Then, touch up with this paint and continue coating.
Coating method
1. Coating can be done by either brush, roller, air or airless spray coating.
- Store the coating equipment after cleaning with an exclusive thinner immediately after use.
Preceding and follow-up coating
1. Preceding coating : DNH-300P(E) HEAT-RESISTANT 300℃ primer (Silicone alkyd)
Remarks
1. Sufficient performance after last coating is achieved after drying for 7 days at 20℃.
2. If the dry film thickness is too thick, the coating may be peeled. So, please be careful of coating management.
3. Do not use the silicone acrylic type as a heat-resistant top coat. The silicone acrylic type results in wrinkles or peeling of the coating.
4. Due to the nature of the paint, it cannot be completely dried at room temperature, and a fully cured coating can be formed only under a temperature of 200℃ for at least one hour.
