Heavy Duty Coating

DNH-600F Heat-resistant 600℃ top coat (silicone)

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

This paint is made by mixing pure silicone resin and is a heat-resistant top coat designed to withstand metal surface temperatures of up to 600℃. It is excellent in heat resistance, adhesion, bending resistance, and oil resistance. It is widely used for new and repair painting on boilers and other structures that require heat resistance.

Coating method
1. Coating can be done by either brush, roller, air spray coating.
- Store the coating equipment after cleaning with an exclusive thinner immediately after use.
Preceding and follow-up coating
1. Preceding coating : DNH-600P HEAT-RESISTANT 600℃ primer (Silicone)
1. If the dry film thickness is too thick, the coating may be peeled. So, please be careful of coating management.
2. 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.
