Features
- Excellent adhesion to automotive engineering plastics.
- Excellent coolant resistance and heat resistance.
- This deacetone-type sealant does not corrode metals or plastics.
Good adhesion when it comes to resin material
High levels of adhesion when it comes to PPS, PBT and PA66, and excellent adhesion and sealing when it comes to resin cases, such as those for inverters and ECUs
Good coolant resistance
Superior cooling liquid resistance makes it suitable for water sealing, such as for water pumps and PCUs
Automation of operations
In a situation where challenges in securing operators are increasing due to declines in the productive-age population, it can serve as an alternative for solid gaskets, enabling the automation of operations.
