Polyurethane Resin 226 is used for a wide range of electrical and electronic potting and casting applications. For example, its low exotherm and low cure shrinkage, make possible the potting of small, heat-sensitive components, as well as the casting of large quantities of the resin at one time. And the very low viscosity of the product makes it possible to quickly fill and impregnate sand-filled modules.
A rubbery castorbased polyurethane that combines very low viscosity with a good workable pot life and a demold time, at room temperature, of as little as six hours. Resin 226 maintains good electrical properties in both wet and dry environments. It also has a long-term heat stability (130°C) and good toughness. Resin 226 is used for a wide range of electrical and electronic potting and casting applications.

And the very low viscosity of the product makes it possible to quickly fill and impregnate sand-filled modules. Resin 226 is formulated with materials that have low volatility at room temperature, minimizing toxicity potential. The isocyanate used is not TDI, and it does not contain MOCA.
Epoxy Resins
The basic Scotchcast™ epoxy resins products include flexible, semi flexible and rigid room-temperature curing and oven curing epoxy resin, some of which are then modified to create filled and thixotropic versions. Other subdivisions, based on temperature, class, colour and special formulations, complete the product line.
