Loctite 121078 - Urethane methacrylate retaining compound

LOCTITE 121078 is a green retaining compound whose higher viscosity makes it a good choice where the max. diametrical clearance is 0.25 mm. It is a high strength product for applications that require a permanent bond and good temperature resistance. Fixture time on steel is up to 3 min and service temperature from -55°C to + 175°C. Fluoresces for presence monitoring.

* single component product, requires no mixing
* high strength for permanent bonds
* suitable for gap filling
* good temperature resistance
* fluoresces for presence monitoring
