3M Scotchcast Electrical Liquid Resins

3M Scotchcast 10N Resin

3M Scotchcast Resin 10N is a filled electrical liquid resin, 2 part epoxy resin for temperature curing with the following features common to the complete range of 3M Scotchcast Electrical Liquid Resins:

• Easy Mixing Ratios
• Moderate to Long Pot Life
• Low Exotherm
• High Adhesion
• Good to Excellent Electrical Properties
• Range of Flexibility and Viscosity

10N Resin is a heavy paste (peanut butter) consistency. 3M resin 10N is for general use. They are versions of 3M resin 9 and exhibit many of its good features. Self extinguishing. No nonylphenol.

3M Scotchcast Resin Temperature Classes

A resin rated in a specific temperature class is deemed capable of operating continuously at that temperature. The Association of Industrial Electrical Engineers (AIEE Standard Number 1) denotes some of these temperature class ratings:
Class O = 90°C (194°F)
Class A = 105°C (221°F)
Class B = 130°C (266°F)
Class F = 155°C (311°F)
Class H = 180°C (356°F)

Typical Applications: Motor or transformer iron, transformer coil, toroidal core, busbar, wound assembly (coil impregnation)

3M Scotchcast Electrical Liquid Resins are 100-percent-solid, thermosetting, electrical-grade insulating resins. Classified chemically as either epoxies or polyurethanes, the 3M Scotchcast product line includes two-part epoxy liquids and two-part polyurethane liquids. The unique electrical and physical properties make them ideal for insulating and protecting electrical and electronic parts and assemblies, including cable joints, splices, connections and cables. Their physical features also make them suitable for nonelectrical, general-use applications, such as adhesives and sealants. 3M Scotchcast Powder Resins are a series of one-part, 100-percent-solid electrical-grade systems offering fast curing, excellent thermal and mechanical shock resistance, significant cut-through resistance, high adhesion, excellent chemical and moisture resistance, high-to-low flow characteristics and excellent electrostatic coating capability.
