Application

JA293-2 is two component epoxy for electronic devices potting. This resin exhibits good handling, chemical resistance and perfect surface gloss. Ideal for general purpose industrial utilities requiring extended work life. A clean surface can be applied, the precise ratio while mixing Part A and Part B, and complete mixing of these two components are required to obtain optimum properties. The durability of this product is very high levels and this resin can pass many environmental test experiments.

This resin has low viscosity and fluidity. It is good for potting.

This product has low viscosity and is good for potting. Cured product has good surface gloss.

This resin produces no exotherm in 5-10 gram masses and very slight exotherm in larger masses.

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

This product obeyes UL94V-0 regulations.
