Tough-Seal is the KEY material for the electronic encapsulation of sensitive electrical components requiring premium thermal cycling performance, excellent thermal shock resistance, and outstanding environmental and corrosion protection.
- Tough-Seal bonds exceptionally well to the walls of most plastic and metallic housings, frames and shells and stays in place without pull back during environmental exposure.
- Tough-Seal has specific and aggressive aluminium adhesion. Specifying engineers love Tough-Seal on aluminum housings when standard potting compounds crack, pull away, or disbond.
- For connectors, Tough-Seal adheres and seals to wire insulation and metal contacts and receptacles.
- It is soft enough to deliver a resilient and durable potting but firm enough to lock down receptacles so they are not prone to push back upon plug insertion.
- Tough-Seal is also now available in a higher viscosity formulation for glob-top encapsulating, allowing for localized potting and protection of vulnerable microelectronic components from environmental, mechanical & electrical damage.

Tough-Seal provides a unique combination of KEY properties not commonly found in just one potting compound.
If you use urethanes, Tough-Seal can extend your service temperature with an isocyanate-free solution that is not moisture sensitive.
If you use silicones, Tough-Seal offers a cost effective, non-silicone option with a friendly ratio and faster cure.
If you use epoxy, which is hard and rigid, Tough-Seal is an upgraded technology with exceptional flexibility that can withstand a wide range of service temperatures. With minimal exotherm, low shrinkage, and minimal expansion and contraction with temperature changes, Tough-Seal delivers low embedment stress, and outstanding thermal cycling performance.
