  1. What is 3M™ Scotchcast™ Electrical Resin 8N, Part B used for?

    It's designed for protecting and insulating electrical components like cables, splices and terminations.

  2. Is it easy to use?

    Absolutely! You'll find that the resin mixes easily in a self-contained plastic bag within the pail. Once mixed, you simply pour or brush it onto your project.

  3. How much does a single pail cover?

    This particular size weighs 40lbs., but how much area it will cover depends entirely on the specific application. Our team can provide more information about usage rates if you give us some details on your project!

  4. Does it have any certifications or ratings?

    Yes! The Scotchcast resin has been thoroughly tested and meets all applicable standards including UL Recognized Component status QOQI2.MH17478. Additionally, this product is RoHS compliant.

  5. Can I store unused/unmixed "Part B" material in the container after I open it?

    :Sure thing! If there are unopened bags of part A & B included inside your purchased unit, these should remain sealed until ready to use (with ideal storage at room temperature). Opened containers can be resealed properly & stored according to local regulations / good practices.

3M™ Scotchcast™ Electrical Resin 8N has a low gel point rating to ensure curing at room temperature. The resin exhibits a semi-flexible and good adhesion property after curing, thanks to its high tensile strength. This makes it ideal for applications that require excellent thermal shock and mechanical shock resistance. Additionally, the high dielectric strength of the resin offers excellent electrical insulating properties.

The resin has a high flash point, which helps prevent any fire hazard in electrical components due to quick ignition. Furthermore, it exhibits hydrolytic stability, which minimizes quick chemical decomposition, thus providing long-lasting usage.

The product is MIL I 16923E and MIL I 16923G certified, and RoHS 2011/65/EU compliant.
