Product Introduction
STD7500 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
High - Temperature Resistance: STD7500 can withstand temperatures up to 800°C, making it suitable for high - temperature environments.
Thermal Insulation: Provides effective insulation to reduce heat transfer and protect underlying materials.
Chemical Resistance: Resistant to common chemicals and solvents, ensuring long - term stability.
Mechanical Strength: Exhibits high hardness and strong adhesion to various substrates, including metals.
Environmental Compliance: Water - based formulation reduces VOC emissions and is environmentally friendly.
Applications
Industrial Processes: Used to protect equipment and components in high - temperature industrial processes.
Automotive Industry: Protects engine components and exhaust systems from extreme heat.
Aerospace: Used in aircraft engines and other components that require high - temperature resistance.
Power Generation: Protects components in power plants, such as turbines and boilers.
