Non-Water Washable Visible Penetrant Fluid, Post-Emulsifiable (Method C), 16 Oz. Aerosol Can, Red, 9 Cans Per Case

DP-40 is a non-water washable visible penetrant used to locate cracks, laps, pores, lack of bonding, and similar surface flaws. DP-40 can be used on nonporous parts including both ferrous and nonferrous metals, ceramics, and glass. Referred to as the "visible dye penetrant" method or "color contrast" method of inspection for weld inspection. Brings flaws into sharper, clearer focus with more intense red color. Performs more reliably over a greater range of temperatures. DP-40 meets stringent low sulfur and chloride requirements. Long lasting flaw mark indications; less fading.Specifications: SAE AMS 2644 & QPL MIL-I-25135 Revisions C, D, & E ASME Code NDT, Sec V
