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 catalyzationDoes not contain any solventsIs non-flammableHas a long shelf lifeRequires storage at ordinary air-conditioned temperatureOdor-freeSpills are easy to cleanCan 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.Information provided by 3M
