Heat-resistant urethane-based hot melt (reactive hot melt) with excellent properties due to bridging reactions.
Conventional hot melts have limitations in heat resistance because they are used by heating and melting thermoplastic resins. To compensate for this drawback in heat resistance, a reactive component is added to the hot melt, which forms a cross-linked structure after application. This is known as moisture-curing urethane-based hot melt (reactive hot melt).
**Features**
- The application temperature is low at 120°C, allowing it to be applied to heat-sensitive films and other materials.
- It can bond various materials such as wood, plastic, aluminum, painted steel sheets, and inorganic materials.
- Being urethane-based, it has good low-temperature properties and excellent cold resistance.
- Compared to conventional hot melts, it has a longer open time, providing a wider range of permissible working time.
**Main Applications**
- Bonding of building materials (profile wrapping, sandwich panels, etc.)
- Assembly of parts for residential equipment (water-related areas)
- Assembly of interior parts such as automotive ceilings and door trims
- Assembly of exterior parts such as automotive headlamps and tail lamps
- IC cards
- Textiles
