Product description
Dymax SpeedMask® 758-H maskant is formulated for UV/Visible and LED light curing to provide good surface protection during acid stripping, chemical milling/etching, plating, anodizing, and aggressive grit-blasting operations. It aids in the manufacture, overhaul, repair, and rework of turbine engine blades, vanes, and other turbine components. It is a Multi-Cure® mask specially formulated to cure with heat in applications where shadow areas exist. This 100% organic resin cures quickly and is peelable, while any internal material can be removed by incineration in an air furnace at a minimum temperature of 650°C [1200°F] leaving a residue-free surface with minimal ash from combustion of the maskant. The removal of the cured maskant on the surface of the component 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, incineration, when applicable 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.
