Dymax OP-4-20641 UV Optical Adhesive (3ml)

The Dymax OP-4-20641 UV Cure Optical Adhesive is a clear, UV or visible light-curable adhesive with high transmission across the optical spectrum, designed for laminating large areas. It exhibits very soft, low modulus properties and is tailored for the thermal cycling of fragile optical components. Dymax Ultra Light-Weld® materials contain no nonreactive solvents and cure upon exposure to light. Their ability to cure in seconds facilitates faster processing, greater output, and lower processing costs. This UV adhesive product is compliant with RoHS standards, aligning seamlessly with directives 2015/863/EU for environmental responsibility.
