3M ™ Polyurethane Resins (226)
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.
-
Good electrical, physical, chemical and thermal properties.
-
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.
