Epotek 301-2 is a long pot life epoxy that stays workable for up to 8 hours. That is much longer than the standard 301, which makes it a preferred choice for large-scale potting and high-volume optical assembly.

Key Features of Epotek 301-2 Long Pot Life Epoxy

• Up to 8 hour pot life
• Optically clear, low stress
• Perfect for large-volume potting

Clear and Gentle

This low-viscosity, two-component system gives excellent clarity. In addition, it cures at room temperature with low stress. As a result, it protects delicate parts such as optical filters, photodiodes and high-purity medical sensors.

Strong Adhesion

301-2 bonds very well to glass, quartz, metals and ceramics. Meanwhile, it keeps high moisture and chemical resistance.

Void-Free Results

The long working time allows full degassing of large volumes. So you get a void-free, transparent finish in complex encapsulation work.

Why Choose This Long Pot Life Epoxy?

Epotek 301-2 suits underwater optics and precision lab instruments. For example, it gives you the clarity, durability and processing flexibility that high-end technical work demands.
