Rome-temp Removable
SM-CS-102
Polyurethane Rome-temp Removable Cryogenic Adhesive
Product Description：
A two-component polyurethane elastic cryogenic adhesive specifically designed to solve the pain points of “requiring room-temperature secondary disassembly and extended application times after cryogenic structural bonding.” Demonstrating excellent elasticity and toughness across a broad temperature range of -269℃ to +60℃, it is widely applicable for the cryogenic sealing and bonding of high-pressure LNG containers, pipelines, and various structures requiring room-temperature secondary removability.
Key Features:
Room-Temperature Removable Elastic Matrix: The cured adhesive maintains an exceptionally low Shore A hardness of 40-50 at room temperature. This highly elastic, low-hardness characteristic provides excellent removability at room temperature, significantly reducing the risk of physical damage during post-maintenance, inspection, and component replacement of cryogenic equipment.
Exceptionally Long Operation Window: Features a prolonged pot life of 80-120 minutes. This parameter provides a substantial time margin for adhesive application on large and complex interfaces, precise alignment of massive structural components, and diverse application methods such as rolling and brushing, thereby significantly improving the fault tolerance of the application process.
Reliable Cryogenic Sealing and Bonding Strength: While maintaining its room-temperature removability, its resistance to extreme cold remains uncompromised, delivering a tensile shear strength of 18 MPa even in the extreme ultra-low temperature environment of -196℃, ensuring the sealing and structural stability of equipment during extreme thermal cycling.
