Tough-Seal Potting Compound
Tough-Seal is a superior family of KEY sealants for potting electrical and electronic components that provides a reliable grip and exceptional encapsulating protection for any potting application where premium thermal cycling performance, excellent thermal shock resistance, and outstanding environmental and corrosion protection are a must.
Tough-Seal is bulldog tough and bred to grip and protect, under the most aggressive conditions!
ToughSeal vs. Other Potting Compounds
Tough-Seal is a RoHS Compliant, easy-to-mix, two component durable hybrid epoxy elastomer that offers a unique combination of KEY properties not commonly found in just one potting compound. It offers the heat resistance of an epoxy, the flexibility of a urethane and the durable encapsulating protection of a silicone. ToughSeal is not a urethane, so it is isocyanate-free and it is not moisture sensitive.
With very low exotherm in large volume pours, extremely low shrinkage, and little to no expansion or contraction with temperature changes, ToughSeal is gentler on sensitive circuitry, than hard epoxies, delivering low embedment stress upon cure and during thermal cycling.
Tough-Seal provides durable encapsulating protection that guards electrical components from exposure to the harmful effects of the environment better than typical epoxies, urethanes and silicones.
