Product description

Dymax SpeedMask® 726-SC Plating, Grit Blast, and Heat-Resistant Maskant with See-Cure Technology with See-Cure technology provides excellent surface protection of turbine and metal components during many plating, decorative etching and anodizing, air plasma spray, blasting, and powder-coating processes. The blue color transitions to pink upon exposure to sufficient light energy indicating full cure has been achieved. 726-SC also has the ability to remain flexible at higher temperature processes up to 204°C [400°F]. This resin cures quickly and is easily removed after processing. When properly cured, 726-SC leaves no residue on non-porous surfaces. The removal of the cured maskant can be aided with the use of a hand tool (plastic, anti-static or metal), heat aided to localize area, an ultrasonic bath, dry ice blast or embrittlement, water jet blast, or automated grippers. Please reach out to Dymax Application Engineering for details on these removal options. SpeedMask resins 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, or flood lamps, they deliver optimum speed and performance for many masking applications. Dymax lamps offer the ideal balance of UV and visible light for the fastest, deepest cures. This product is in full compliance with RoHS directives 2015/863/EU.
