3M reveal new colour-changing resin to combat high-moisture environments
A new low-voltage electrical jointing resin from 3M will provide premium protection for cables – which changes colour to indicate when it is ready to be applied.
The science-based technology company’s Scotchcast Epoxy Resin 4GS is an easy-to-use two-part encapsulating resin with unique colour changing features, for the safe and easy installation and protection of electrical cables.
Enhanced humidity resistance makes application in the presence of water easier – a common issue when working in challenging electrical construction environments.
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 is easily mixed by breaking the internal seal and 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, 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.
The resin, available in different size options, is free of CMR (Carcinogenic, Mutagenic or Toxic for Reproduction) and SVHC (Substance of Very High Concern) for safer handling.
The resin is also available as part of the 92 series GS Resin Kit range, which also includes an innovative one-piece transparent mould body for ease of use and visual control in the delivery of resin.
The one-piece transparent mould body 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 new Scotchcast Epoxy Resin 4GS from 3M 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 indoor, outdoor, 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.
