Product Introduction
Gulite Blue sealant is a new generation neutral RTV silicone sealant, designed for non-gasket sealing applications. The product cures at room temperature to form a highly elastic rubber sealing layer, which can replace traditional gaskets and achieve stable sealing performance.
The product has a light blue paste structure with excellent thixotropic properties. It does not sag or flow, making it suitable for complex or vertical surface applications. It uses a neutral curing system, which does not corrode metals or contaminate components, and is compatible with various metals and composite material interfaces.
Temperature resistance range is -60℃ to +300℃, and pressure resistance can reach 12MPa, making it suitable for high-temperature engines and high-pressure industrial systems.
-
- Strong Oil Resistance: It has excellent resistance to engine oil, gear oil, and other media. Its oil resistance is more than twice that of ordinary silicone sealants.
- High Toughness and High Elongation: After curing, it can be stretched up to 4 times its original length, effectively absorbing vibration and impact.
- Strong Adhesion: Metal surface adhesion strength is about 15kg/cm², forming a stable and long-lasting sealing layer.
- Wide Temperature and Pressure Resistance: It maintains stable performance under -60℃ to +300℃ and 12MPa conditions.
- Neutral and Environmentally Friendly: It is non-corrosive and has no irritating odor, suitable for precision equipment and metal component assembly.
Product Applications
RTV silicone sealant has a wide range of applications. Gulite Blue products have mature use cases in multiple industries and can meet sealing and bonding needs under different working conditions.
-
- Automotive and Transportation Equipment: The product is commonly used for engine covers, transmission joint surfaces, lamp sealing, and chassis component waterproof and oil-proof sealing. Its oil resistance and vibration resistance allow it to maintain stable bonding performance in complex operating environments, improving vehicle durability.
- Electronics and Electrical Industry: In control boxes, LED lamps, and power modules, RTV silicone sealant is used for moisture-proofing, dust-proofing, and insulation protection. Its excellent electrical insulation performance reduces the risk of short circuits and improves product safety.
- Construction and Industrial Installation: In curtain wall joints, metal structures, and industrial equipment installation, the product provides a long-lasting elastic sealing layer, adapting to structural movement caused by temperature changes and reducing cracking and leakage issues.
- Machinery Maintenance and Repair :In maintenance applications, RTV silicone sealant is often used to replace traditional gasket materials, especially in high-temperature or high-pressure conditions for temporary or permanent sealing applications.
Overall, the product has become a universal material in industrial sealing systems due to its excellent weather resistance and adaptability.
