Dymax OP-4-20655 Optical Adhesive, Fiber Optic Assembly, Optically Clear, UV Cure - 30ml Syringe

The Dymax OP-4-20655 Adhesive for Fiber Optic Assembly is a clear, low-shrinkage, UV/visible light-curable adhesive. Formulated as a very soft, shock-absorbing, low-modulus material, it is ideal for thermal cycling of fragile optical components. Dymax high-performance optical adhesives cure in seconds under UV or visible light, helping increase productivity, reduce assembly costs, and enhance operator safety. This fiber optic adhesive is fully compliant with RoHS Directive 2015/863/EU. Packaged in a 30 ml syringe.
