keo UV SpeedMask® Masking Resin 758-H

SpeedMask® 758-H maskant is formulated for UV/Visible and LED light curing to provide good protection during 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. Recommended surfaces include titanium alloys and nickel alloys.

SpeedMask® resins have no solvents added 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.

SpeedMask® 758-H is in full compliance with RoHS Directives 2015/863/EU.
