This product offers excellent optical clarity and light transmission properties. It has high bond strength to similar and dissimilar substrates including treated metals, glass and many plastics. Its viscosity is 100,000-150,000 cps. LED403Med has excellent dimensional stability and superior electrical insulation properties. It also is resistant to gamma radiation, ETO and various chemical sterilants.

Cure speeds in thin sections can be achieved in 15-30 seconds. Speed of cure depends upon the intensity of the light source, the thickness of the layer and the distance of the light source from the material being cured. LED403Med contains no solvents or diluents. It fully cures tack-free without any oxygen inhibition.
