731-REV-A


Next-Generation Maskant for Aggressive Processing & Plating

SpeedMask® 731-REV-A fast, light-curable maskant offers excellent surface protection of components during vibratory finishing, plating, shot-peening, anodizing, and aggressive grit-blasting operations. The product is used for the manufacture, repair, rework, and overhaul of turbine parts, vanes, and engine blades. 731-REV-A is bright yellow before cure enabling visual confirmation of material placement onto substrates. After cure the material fluoresces bright yellow under black light for easy quality inspection.

This 100% organic thixotropic gel is sprayable onto components, exhibits high adhesion, and cures quickly. The masking resin is trimmable after cure, is easily peeled off a with a hot-water soak, and leaves no residue on surfaces when properly cured. Recommended substrates include nickel alloys, steel, stainless steel, aluminum, titanium, cobalt, and glass.

Dymax materials are solvent free and cure upon exposure to light. Their ability to cure in seconds results in lower processing costs. When cured with Dymax UV 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 ideal balance of UV and visible light for the fastest, deepest cures. SpeedMask® 731 is in full compliance with the RoHS2 Directives 2015/863/EU and 2011/65/EU.
