Description
3M™ Scotchcast™ Electrical Powder Resin 260 is a high-performance, one-part, green-pigmented, rapid heat-curing epoxy resin designed to deliver a tough, continuous, moisture-resistant and chemical-resistant dielectric coating. Formulated using 3M’s precision fusion-blend manufacturing process, each powder particle contains all components required for a complete cure, ensuring consistent quality and excellent coating performance.
When applied to a preheated substrate, Resin 260 melts, flows smoothly, and cures into a uniform, thick, and durable protective layer. It is ideal for use in electrical insulation, motor and transformer protection, and moisture-proofing critical components.
