Product Description of epoxy potting compound:
Epoxy potting compound is a high-performance insulating and sealing material, mainly used to protect electronic components through potting, filling, or encapsulation, and cured at room temperature or by heating.
Epoxy potting compound is a thermosetting polymer sealant made from epoxy resin as a matrix, with the addition of curing agents, fillers, and additives. Its core characteristic is that it is poured into electronic components or devices in a liquid state, and then cures through a chemical reaction to form a hard, dense solid protective layer, achieving comprehensive encapsulation of internal components.
Product Features of epoxy potting compound:
With low viscosity, long operation time, good fluidity, and easy penetration into the clearance of the product; no bubbles after curing, smooth surface, luster, high hardness; curing materials have good acid and alkali resistance, moisture-proof, moisture, and air aging; curing materials have excellent insulation, compressive resistance, and bonding strength
