SpeedMask®

750-SC

High-Temperature See-Cure Maskant for Thermal Spray Coatings


This product is only available in the United States & Europe. For use in Asia, country compliance should be reviewed with the regional Dymax team.

UV/Visible light-curable SpeedMask® 750-SC maskant provides excellent surface protection during higher temperature thermal spray coating, plasma spray, and HVOF processes as well as aggressive grit blasting. This product features patented See-Cure technology with transitions the resin’s purple color to pink upon exposure to sufficient light energy, indicating full cure has been achieved. The material offers excellent protection during surface finishing of metal components used in aerospace engine, orthopedic implant, and general masking applications.

SpeedMask® 750-SC maskant is easily removed by incineration in an air furnace at a minimum temperature of 650°C [1200°F]. The masking resin can also be removed from coated substrates after short exposures to warm water (60°C +) or warm air. This exposure will soften the maskant and allow for easier removal. The product is recommended for surfaces such as nickel alloys, titanium alloys, and cobalt chrome.

SpeedMask 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 optimum balance of UV and visible light for the fastest, deepest cures. SpeedMask® 750-SC maskant is in full compliance with the RoHS2 Directives 2015/863/EC.
