Features and Applications
High - Temperature Resistance: Can be used for long - term service at temperatures up to 300°C ± 5°C. When formulated into heat - resistant coatings, it can withstand temperatures of 600 - 800°C.
Good Mechanical Properties: The coating dries quickly, with good adhesion and excellent flexibility.
Wide Range of Applications: Suitable for manufacturing specialized heat - resistant paints for exhaust pipes, ovens, fireplaces, electric stove plates, etc.
Usage Instructions
Avoid contact with acids, bases, organic salts, amines, and other substances during use, as this may lead to accelerated curing or gelation.
The compound is particularly sensitive to alkalis, so it is important to select neutral materials when formulating paints.
Sealing Compounds 9802R is a high - performance sealing material, suitable for sealing applications in high - temperature environments. It boasts excellent heat resistance and mechanical properties and is widely used in industrial applications.
