Application

JB350-2 is two component epoxy for LED module casting. This product exhibits low viscosity, good handling, chemical resistance and perfect surface gloss. This resin has high reactivity and good thermal shock resistance. This product still has good adhesion strength and properties after the environmental test experiments.

When curing, this resin will not change its properties because of moisture.

Cured product has good adhesion strength. The hardening surface will not exhibit a surface oiliness and poor gloss. This product exhibits good chemical and solvent resistance.

The retained strength of this resin after environmental test experiments is excellent.

This resin has medium viscosity and is easy to mix. It has excellent operating properties.

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