Dymax SpeedMask 729 Plating and Harsh Chemical Mask
SpeedMask® 729 UV light-curable masking resin is formulated to provide excellent surface and cavity protection of turbine components during acid stripping, high-temperature plating processes, and other harsh chemical operations. This 100% organic resin cures quickly with proper UV energy exposure and is easily removed by incineration at minimum of 650°C [1200°F] leaving a residue free surface with minimal ash from combustion of the maskant. 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.
