High-Temperature Insulating Paint STD7501
Functional additives 2025-05-14
Product Introduction
STD7501 is an inorganic silicone one-component high-temperature resistant insulating paint. It can cure at room temperature or under heating conditions, exhibits excellent adhesion to metals, polymers, glass, and other materials. After curing, it can withstand long-term use at 1200°C and a maximum temperature of 1800°C. It can be used as a primer, intermediate coat, or topcoat in atmospheric environments and is suitable for almost all metals (no additional treatments such as sandblasting required).
Key Features
Exceptional Thermal Insulation: STD7501 provides outstanding thermal insulation, effectively reducing heat transfer and protecting underlying materials from high – temperature damage.
High – Temperature Resistance: Capable of withstanding temperatures up to 1.200°C, making it suitable for the most demanding high – temperature environments.
Chemical and Corrosion Resistance: Exhibits excellent resistance to chemicals and corrosive substances, ensuring long – term durability and performance.
Strong Adhesion: Forms a strong bond with various substrates, including metals, ceramics, and composites, providing reliable protection.
Easy Application: Can be applied using standard painting methods such as spraying, brushing, or dipping, making it convenient for a variety of surfaces and applications.
Applications
Industrial Furnaces: Protects the interior and exterior surfaces of industrial furnaces and kilns from extreme heat.
Automotive Exhaust Systems: Coats exhaust pipes and components to reduce heat transfer and protect surrounding areas.
Aerospace Components: Used on aircraft engine parts and other components that require high – temperature resistance.
Power Generation Equipment: Applied to turbines, boilers, and other power generation components to enhance thermal efficiency and protect against heat – related damage.
