Epotek 302 is a versatile two-part epoxy that cures quickly at room temperature. It offers strong resistance to harsh chemicals, solvents and moisture. As a result, it is a reliable choice for bonding, sealing and small potting jobs in electronics and industry.

Why choose Epotek 302?

Many room temperature epoxies take a long time to build strength. However, Epotek 302 develops strong bonds in a short time, with a cure of around two hours. This helps keep your production moving.

It uses a simple 1:1 mix ratio by weight or by volume. Therefore, it is easy to mix and hard to get wrong. In addition, its smooth consistency makes it easy to apply by hand.

The cured epoxy bonds well to metals, ceramics and most technical plastics. It also forms a tough barrier against solvents and high humidity.
