Ultra Light-Weld® Chemical Milling & Harsh-Environment Processing Maskant

SpeedMask® 734-BT UV/Visible light curable masking resin is formulated to provide good surface protection during chemical milling/etching, plating, anodizing, and aggressive grit-blasting operations aiding in the manufacturing, overhaul, repair, and rework of turbine engine blades, vanes, and other turbine components. 734-BT is impervious to most acid and alkali solutions. When cured, it provides surface protection from chemical processing of nickel alloys, steel, titanium, stainless steel, aluminum, and glass.

SpeedMask 734-BT is a fast-curing, solvent-free organic resin designed for either spray or dip masking of components. Used as a temporary protective coating, SpeedMask 734-BT is a replacement for environmentally hazardous and time-consuming solvent- or water-based maskants. 734-BT requires no mixing prior to use.

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.
