Protective Coating

7501-T-UR-SC

LED-Curable Resin for Sealing Plastics and Metals


Dymax 7501-T-UR-SC protective resin cures with either 385 nm or 405 nm UV wavelength light sources for fast sealing of multiple substrates typically used in critical automotive components and assemblies. The product features Encompass® Technology which combines Dymax patented See-Cure and Ultra-Red® fluorescing technologies into one product. The bright blue color of products formulated with See-Cure technology transitions to colorless when the bond line is exposed to the proper amount and wavelength of energy, providing a visual indication of complete cure.

The Ultra-Red fluorescing component of this material fluoresces bright red under low-intensity black light (365 nm). The bright red color contrasts extremely well on many substrates like PC, PET flex circuits, and PVC greatly assisting with visual inspection of the cured resin. Recommended substrates include tin-plated brass, PC, ABS, PMMA, and even PET flex circuit. This is a permanent protective resin and is not intended for removal.

Dymax materials contain no nonreactive solvents and cure upon exposure to light. Their ability to cure in seconds enables faster processing, greater output, and lower processing costs. When cured with Dymax light-curing spot lamps, focused beam lamps, flood lamps, or conveyor systems they deliver optimum speed and performance for maximum efficiency. Dymax lamps offer the optimum balance of UV and visible light for the fastest, deepest cures.

7501-T-UR-SC protective resin is in full compliance with the RoHS2 Directives 2015/863/EU.
