Yellow Fluorescing Maskant is Easy to See on Dark Substrates

Dymax Corporation’s new SpeedMask^® 731 masking resin is yellow in color, making it ideal for use on darker colored substrates where other maskants might be difficult to see.  It also fluoresces bright yellow under black light, making it easy to confirm proper placement prior to processing and clean removal after processing.  731’s high level of adhesion enables it to protect substrates during aggressive blasting processes and chemical exposures.  It has excellent adhesion to nickel alloys, steel, stainless steel, aluminum, titanium, cobalt, and glass and can be used in a variety of industries including aerospace, power generation, orthopedic joint replacement, and precision metal finishing.

SpeedMask^® 731 is jettable and holds its shape after application.  It cures tack-free on demand for quicker handling, is easily removed through peeling or incineration, and leaves no residue upon removal from non-porous surfaces.  Its 500% elongation and very low shrinkage properties make it a resilient post-cure maskant.  SpeedMask^® 731 saves hours of processing time when used as an alternative to labor-intensive manual taping or lacquer maskants with long cure cycles.
