Composition and performance:
Made of silicone epoxy heat-resistant resin, polyTwo-component high temperature resistant oxidation mortar made of ester epoxy resin, polyamide curing agent, wear-resistant aggregate, heat-resistant pigment and filler, etc.
The paint film has excellent resistance to sudden temperature changes and can withstand high temperatures of 200-400°C for a long time.
The paint film has excellent high temperature resistance and anti-rust performance, and the paint film has excellent physical and mechanical properties
Excellent adhesion between paint film and steel surface
use:
It is suitable for anti-rust coating of metal surfaces below 400℃ in industries such as metallurgy, chemical industry, petroleum, electromechanical machinery, etc. It has remarkable effect on the inner and outer walls of blast furnace hot blast stoves, flues, exhaust pipes, heating furnaces, heat exchangers and other high-temperature metal surfaces.

Construction instructions:
Main agent: curing agent = 13:1, stir evenly, add epoxy silicone diluent and apply.
Surface treatment:
The steel surface treatment is carried out in accordance with the national standard "Surface rust grade and rust removal grade of steel before painting" GB8923-88. Sandblasting rust removal reaches the national standard Sa2.5 grade, and manual rust removal reaches St3 grade.
Notes:
1. The paint should be stored in a low temperature, ventilated and dry place; away from fire and heat sources; the shelf life is one year in a cool and dry place.
2. The above information is written based on actual testing and usage experience of our company's technical personnel and can be used as a construction guide. However, due to differences in coating environments and supporting solutions, it is recommended that users conduct preliminary experiments and tests based on actual needs and uses before confirming use.
