Multipurpose thread sealant for use on metals including steel, stainless steel, brass, copper, aluminum, and on plastics including PVC, CPVC, and ABS. Leak-free joints can be tested and put into service at once. Megaloc wipes clean from hands and tools with a dry rag, is odor-free, grit-free, and will not separate or settle. Megaloc does not harden, crack, or become brittle; joints can be disassembled without damage to pipe, fittings, or threads years after the joint was made. Megaloc is applied easily with a natural bristle brush even at temperatures as low as -25 deg (degrees) F, and performs over a temperature range of -50 deg F to 400 deg F. It provides leakproof hydraulic resistance to 12,000 psi and withstands gas pressure up to 2600 psi. Megaloc is nonhazardous and nonflammable. It contains no lead, heavy metal, or volatile solvents.
