Temporary SpeedMask® Maskant for Laser Drilling

SpeedMask® 707 maskant cures with UV/Visible light and secondary heat-cure in applications where shadow areas exist. 707 masking compound is hard and durable and provides excellent internal cavity protection of turbine components during laser drilling operations. The product prevents beam impingement and reduces spatter. This low-viscosity masking resin flows easily into cavities and achieves full depth of cure with heat. The material is 100% organic, cures quickly, and is easily removed by incineration at a minimum 650°C [1,200°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 ideal balance of UV and visible light for the fastest, deepest cures. SpeedMask® 707 is in full compliance with the RoHS2 Directives 2015/863/EU.
