PRODUCT DESCRIPTION
Hernon ReAct 761 is a tough acrylic adhesive designed primarily for bonding
permanent magnets. ReAct 761 has also found wide acceptance in a variety of
structural bonding applications due to its versatile performance capabilities. ReAct
761 provides high tensile strength while maintaining excellent product flexibility.
This results in tough durable bonds with outstanding impact and peel resistance.
Temperature resistance from 40C (-40F) to 204C (400F). ReAct 761 is a single
component adhesive used in combination with Hernon EF Activator 59 or EF
Activator 63 for curing at room temperature. The adhesive may also be heat cured
at 150C.

Typical Curing Performance
ReAct 761 is designed to be used with EF Activator
59 or 63 and cured at room temperature. Cure
characteristics are measured by determining fixture time
(handling time) and speed of cure.
Fixture Time
Fixture time is defined as the time to develop a shear
strength of 0.1 N/mm².
