Relicon Cast Resin PUR 33 is a high-performance two-component polyurethane (PUR) casting resin designed for dependable electrical insulation, sealing, and mechanical protection in demanding industrial and infrastructure applications. It is widely used as an equivalent alternative to 3M™ Scotchcast™ 2131, offering comparable performance for cable jointing and electrical encapsulation tasks.
PUR 33 cures to form a flexible, durable protective compound with excellent resistance to moisture, vibration, and thermal cycling. Its controlled curing characteristics ensure consistent results in both simple and complex moulding or jointing applications.
