3M Scotchcast™ 265 Electrical Epoxy Powder Resin
Categories: Polymer; Thermoset; Epoxy; Epoxy Cure Resin

Material Notes: 3M Scotchcast Electrical Resin 265 is a new solution to an old problem. Historically, manufactures of coils, stators and armatures have used liquid-based varnishes or resins to coat and impregnate the copper windings to obtain better heat transfer, mechanical strength and environmental protection. However, these liquids – originally natural resins, now mostly synthetic – have presented a number of problems to the user during the manufacturing process. Scotchcast 265 solves many of these problems:
  • Does not require any mixing or catalyzation
  • Does not contain any solvents
  • Is non-flammable
  • Has a long shelf life
  • Requires storage at ordinary air-conditioned temperature
  • Odor-free
  • Spills are easy to clean
  • Can be applied to trickle, spray or dip processes.
Scotchcast 265 is a powder. It is simply applied to the heated winding where it melts, flows into the wire interstices and cures. Low melt viscosity and minimum build make this powder ideal for a variety of coating and bonding applications.
