This sealant putty, manufactured by Duraline, is engineered for exceptional performance across a wide temperature range, ensuring effective sealing in conditions from 20 F to 100 F. Its non-toxic composition makes it safe for various applications, as it contains no asbestos fibers, nor does it produce harmful emissions, being free from TDI, CFCs, and HCFCs. Ideal for multi-purpose use, it functions both as a sealing compound and a moisture barrier, boasting superior tack that promotes excellent adhesion between dissimilar surfaces, including compatibility with all cable jackets, even semi-conductive types. One of the standout features is its impressive ability to withstand up to 70 feet of water head pressure, making it a reliable choice for sealing applications exposed to moisture. In addition to its strong sealing properties, the putty remains pliable for at least 10 years without shrinking, drying out, or cracking, even when subjected to UV exposure. This durability, paired with its stability at both low and high temperatures, makes it an essential tool for construction, electrical, and plumbing needs. Each 5 lb package comes in cases of six, ensuring that you have an ample supply for your projects.
