| Tech Optics offers epoxy adhesives for the termination of optical fibres. Two types are available: RT153FC (Fast Cure) intended as a substitute for the"353" adhesive and a versatile RT156 product that can be heat cured or allowed to cure at ambient temperature (25ºC) for 24 hours ("overnight"). These materials are available in 2g or 4g sachets with 5 sachets supplied in a foil sealed bag. Epoxy Applicators are available for dispensing epoxy into connectors. |
