  1. What is 3M™ Scotchcast™ Reenterable Electrical Insulating Resin 2123D?

    The 3M™ Scotchcast™ Reenterable Electrical Insulating Resin 2123D (21.2 oz) Size E, 10/Case is a two-part polyurethane resin that provides excellent electrical insulation and helps protect from harsh environmental factors like moisture and chemicals.

  2. How does the product work?

    The polyurethane resin forms an insulating barrier around cables or splices by filling in air voids and gaps, effectively sealing out moisture and other foreign materials. This helps to prevent electrical malfunctions caused by water exposure or corrosion.

  3. How can this product benefit me?

    By providing excellent protection against moisture and chemicals, the 3M™ Scotchcast™ Reenterable Electrical Insulating Resin can help ensure your equipment stays functional for longer periods of time without experiencing issues related to dampness or chemical damage. In addition, it's re-enterable property allows for maintenance personnel to perform future splicing operations with ease.

  4. Q: Are there any special use instructions I should know about before using this product?

    A: Instructions on how to use the product are included on the package but generally involve mixing Parts "A" & "B", pouring solution into place around cable-in-conduit assembly or splice-case using suitable tools such as rollers . After curing period specified usage could resume again if needed also with capabilities to open incase adjustments need be made
