Application

JA331 is two component epoxy for auto lamp and electronic devices casting. This resin has good transparency and reactivity .Cured product exhibits low outgassing properties, excellent thermal shock resistance excellent stability in many environmental tests.

This resin is solvent-free, non-volatile, two component system.

The hardening surface will not exhibit a surface oiliness and poor gloss.

When curing, this resin will not affect by moisture.

This product exhibits low outgassing properties.

This product complies to the 2011/65/EU RoHS regulations.
