Two-Component Flexible Epoxy Potting Compound ZLA-6204
ZLA-6204 is a 4:1 flexible epoxy potting compound that adds a modest heat path (0.4 W/m·K) to crack-resistant encapsulation.
It cures at room temperature or with heat and is tack-free in about 120 minutes, leaving time for larger pours, before reaching Shore A 80 with 7 MPa lap shear on aluminium.
Mixed density is 1.65±0.2 g/cm³, and heat-aged samples stayed crack-free (see the typical values).
