Low voltage electrical jointing resin launched

Louise Davis

The new Scotchcast Epoxy Resin 4GS from 3M features unique colour changing properties and enhanced humidity resistance for electrical cable protection.

It has enhanced humidity resistance to make application in the presence of water easier, a common issue when working in challenging electrical construction environments. It's new colour-changing properties provide electricians, engineers and installers with a clear indication of when the resin is correctly mixed and a further colour change when fully cured, ensuring a reliable cable joint.
The resin has a CMR (carcinogenic, mutagenic or toxic for reproduction) and SVHC (substance of very high concern) -free formulation for safer handling.
Available in different size options, the two-component Epoxy Resin 4GS bag is easily mixed by breaking the internal seal, combining the resin and hardener mix. Within two minutes, the resin turns green to indicate the components have started reacting correctly and are ready for pouring. The average time for the curing to occur ready for energisation of the cable is 30 minutes, and is confirmed when the resin changes to a blue colour. These features provide a rapid, mess-free installation with clear indications of the mixing and curing process, reducing the time involved in installation and providing safe and easy electrical cable jointing. Once fully cured, the resin provides an energised insulation, impact resistance and durability, and premium protection against moisture and atmospheric corrosion.
It is also available as part of the 92 series GS Resin Kit range. This also includes a one-piece transparent mould body for ease of use and visual control in the delivery of resin. This also offers an integrated spout with a pre-cut sealing element. Directly connecting the resin bag’s integrated nozzle and spout to the transparent mould allows for clean mould filling, minimising the risk of contact with the resin.
The resin is suitable for the electrical insulation and protection against environmental influences of low voltage electrical joints up to 0.6/1.0(1.2) kV, and mechanical protection of electrical joints up to 20.8/36(42) kV, installed for indoors, outdoors, underground and submerged applications. It is also classified as L-I-W, L-OP-W and M-OP-W according to IEC 60455-3-8.
