Dymax OP-81-LS Low-Shrink™ optical positioning epoxy is engineered for bonding delicate optical components where alignment stability is critical. The material cures quickly with UV/Visible or LED light and includes a low-temperature heat-cure option for shadowed areas or heat-only processes.

Key technical advantages:

• Very low shrinkage and CTE for stable, accurate alignment
• Fast light cure with optional 80–85°C heat cure
• Compatible with glass, polycarbonate, acrylic, and metals
• Meets ASTM E595 outgassing requirements
• One-component, no solvents added formulation
• Cold storage required (1–5°C)

Ideal for optoelectronics assembly where precision, clarity, and long-term stability are essential.
