Application

Provide excellent bonding properties, electrical properties, moisture resistance and mechanical properties, and has high bonding strength for most substrates including glass, metal, ceramics, etc. At the same time can meet the high temperature bonding and mechanical performance requirements, widely used in automotive electronics, pressure sensors, wiring harnesses, motor magnetic sheet bonding.

How to use

Use process

If the epoxy glue is stored in a frozen environment, it should be removed to a normal temperature environment before use. During the sizing process, avoid exposing the glue to high temperatures to reduce the consistency of the glue, unless this has been previously tested and proved to be feasible.
Apply the glue directly to the surface of the object to be bonded after oil removal, rust removal and roughening treatment, select appropriate tools to assist the glue application, and fix it with a fixture. Then cure according to the recommended heating conditions.
