3M Scotchcast ™ Electrical Resin 226 is a Two-Part, Room-Curing, Unfilled, Polyurethane Liquid Resin in the form of a rubbery castor based polyurethane that combines very low viscosity with a good workable pot life and a de-mould time, at room temperature, of as little as six hours. 3M Scotchcast ™ Resin 226 maintains good electrical properties in both wet and dry environments and offers long-term heat stability (130ºC) in an overall tough material. Scotchcast ™ Resin 226 is manufactured with materials that offer low volatility at room temperature, thus minimising toxicity potential. The isocyanate used is not TDI, and it does not contain MOCA.

Excellent hydrolytic stability.
-
Low viscosity
-
3M Scotchcast Resin 226 is used for a wide range of electrical and electronic potting and casting applications.
-
Scotchcast Resin 226 has low exotherm and low cure shrinkage, making possible the potting of small, heat-sensitive components, as well as the casting of large quantities of the resin at one time.
-
The very low viscosity of the Scotchcast Resin 226 makes
it possible to quickly fill and impregnate sand-filled
modules.
