729

Ultra Light-Weld® Plating and Harsh Chemical Maskant

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. SpeedMask 729 protects component substrates such as nickel alloys and high-temperature alloys. This 100% organic resin cures quickly and is easily removed by incineration at 650°C [1200°F]+.

Dymax 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. This product is in full compliance with the RoHS Directives 2002/95/EC and 2003/11EC.
