Epotek 301-2 is a specialized, optically clear epoxy adhesive that offers a significantly longer pot life (up to 8 hours) compared to the standard 301 formula, making it the preferred choice for large-scale potting and high-volume optical assembly. This low-viscosity, two-component system provides exceptional clarity and low-stress curing at room temperature, which is critical for protecting delicate components such as optical filters, photodiodes, and high-purity medical sensors. The 301-2 demonstrates superior adhesion to diverse technical substrates, including glass, quartz, metals, and ceramics, while maintaining high moisture and chemical resistance. Its long working time allows for the complete degassing of large volumes, ensuring a void-free, transparent finish in complex encapsulation tasks. Whether used in the manufacturing of underwater optics or precision laboratory instrumentation, Epotek 301-2 provides the clarity, durability, and processing flexibility required for high-end technical applications.
