Product Description
Organic silicon high-temperature resistant paint, also known as high-temperature paint, heat-resistant paint, is divided into organic silicon and inorganic silicon high-temperature resistant paint series. High-temperature resistant paint, as the name suggests, is a type of paint that can withstand high-temperature oxidation and other medium corrosion.
- The high temperature in the coating industry is generally between 100°C and 800°C.
- The paint is required to maintain stable physical properties in the above-mentioned environment: no peeling, no blistering, no cracking, no powdering, no rusting, and allowed to have slight color change.
Product Application
The organic silicon high-temperature resistant paint is widely used in the inner and outer walls of blast furnaces and hot blast stoves, chimneys, flues, drying channels, exhaust pipes, high-temperature hot gas pipelines, heating furnaces, heat ex-changers, as well as other non-metallic and metallic surfaces for high-temperature anti-corrosion protection.

Construction process
- (1) Pre-treatment: The surface of the substrate must be treated by sandblasting to reach Sa2.5 level;
- (2) Wipe the surface of the workpiece with thinner;
- (3) Adjust the viscosity of the coating with the specific matching thinner. The thinner used is the specific one, and the dosage is approximately: for airless spraying - about 5% (by coating weight); for air spraying - about 15-20% (by coating weight); for brushing - about 10-15% (by material weight);
- (4) Construction method: Airless spraying, air spraying or brushing. Note: The substrate temperature during construction must be higher than the dew point by 3°C, but not higher than 60°C;
- (5) Coating curing: After application, it will naturally cure at room temperature and be put into use or be dried in a room at 5°C for 0.5-1.0 hours, then placed in a 180-200°C oven for baking for 0.5 hours, taken out and cooled before use.
Other construction parameters: Density - approximately 1.08g/cm3;
Dry film thickness (one coat) 25um; Wet film thickness 56um;
Flash point - 27°C;
Coating application amount - 120 g/m2;
Coating application interval time: 8-24 hours at 25°C or below, 4-8 hours at 25°C or above
Coating storage period: 6 months. Beyond this period, it can still be used if it passes the inspection and is qualified.
