High-temperature adhesives are specialized adhesives designed to withstand extreme temperatures without losing their bonding properties. They are classified based on their chemical composition and application methods:
Epoxy-Based High-Temperature Adhesives:
Usage: Bonding metals, ceramics, and composites in applications like automotive, aerospace, and industrial manufacturing.
Application Method: Typically two-part systems (resin and hardener) that require mixing before application. They cure at room temperature or with heat.
Silicone-Based High-Temperature Adhesives:
Usage: Sealing and bonding in high-temperature environments such as ovens, gaskets, and electrical insulations.
Application Method: Available as one-part or two-part systems. One-part silicones cure with moisture, while two-part systems require mixing.
Polyimide Adhesives:
Usage: Used in electronics, aerospace, and other high-performance applications due to their excellent thermal stability.
Application Method: Often require heat curing and are applied as films or pastes.
Ceramic-Based Adhesives:
Usage: Bonding and coating in extreme environments such as furnaces, turbines, and exhaust systems.
Application Method: Applied as pastes or coatings and typically require high-temperature curing.
Phenolic Adhesives:
Usage: Bonding wood, metals, and composites in high-temperature applications.
Application Method: Require heat and pressure for curing.
