One of the most frequently asked questions in electrical and electronic component protection is whether to use polyurethane or epoxy resin. Both systems can deliver reliable insulation — but they differ significantly in mechanical behaviour, flexibility, temperature tolerance, and service accessibility. Polyurethane Resin: Key Properties Advantages: Wide hardness range — formulatable from Shore A (soft) […]

Selecting a potting resin is not just a question of brand or hardness. The wrong system can lead to incomplete cure, mechanical cracking, service difficulties, or application failure. This guide covers the five most important criteria to evaluate when choosing a potting resin. Criterion 1: Service Access — Will the Connection Need to Be Reopened? […]

Potting and encapsulation are two of the most frequently confused terms in electrical and electronic component protection. While both serve similar protective purposes, they differ significantly in application method, depth of protection, and service accessibility. Why Is Junction Box Insulation Necessary? Condensation and moisture ingress — particularly in underground or outdoor installations Capillary water entry […]

Cable joints are among the most vulnerable points in any electrical distribution system. Selecting the wrong material — or applying it incorrectly — can lead to moisture ingress, corrosion, and long-term failure. This guide covers polyurethane resin potting for cable joints step by step. Why Use Resin for Cable Joint Filling? An unprotected cable joint […]
