This low-viscosity formula is optimized for precision tasks such as lens bonding, optical fiber alignment, LCD assembly, and the shallow potting of medical sensors and devices. A standout technical feature of OG142-87 is its dual-cure capability; while it cures rapidly under UV light, it also supports a secondary thermal post-cure to ensure complete polymerization in shadowed areas where UV light cannot reach. Once fully cured to a Shore D hardness of 82, it provides exceptional environmental stability and moisture resistance, making it suitable for solar and opto-packaging industries. To maintain its chemical integrity and ensure a 12-month shelf life, this high-performance adhesive requires strictly controlled storage at 5-10°C. Whether used for glob top filling or critical fiber optic joins, Epotek OG142-87 delivers the reliability and precision demanded by the most advanced technical sectors.
