RBC #2365 is a thixotropic version of RBC#2360. RBC#2365 is a non-sag adhesive. It exhibits high peel strength, excellent shock and vibration resistance. Cured properties can be varied with the amount of hardener used, allowing a wide range of resiliency. It is ideal for bonding materials with different coefficients of thermal expansion. RBC#2365 bonds well to nickel, aluminum, nylon, polypropylene, glass and wood.

Weigh the desired amount of #2365 Resin into a clean container and combine with AB-528 Hardener in one of the ratios shown below. Mix thoroughly for a minimum of three minutes by hand, or one minute by machine.
Semi-Flexible, Impact and Shock Resistant: 100 parts RBC #2365, 100 parts Hardener AB-528
Flexible, Excellent Peel Strength: 100 parts RBC #2365, 132 parts Hardener AB-528
Pot life ranges from 1 – 2 hours depending on batch size and hardener ratio. Cure for 72 hours at room temperature (25oC) or 2 hours at 65oC. For optimum properties, cure 1 hour at 65oC followed by 1 hour at 120oC.
