Black Sealant 16lb Canister was created for those agriculture, automotive, industrial and outdoor applications that need to be sealed and insulated with a water and airtight seal. It is specifically formulated for outdoor use and is black in color si it won't discolor if exposed to UV radiation. It is resistant to heat and reduces noise pollution in auto and trailers. It may be used in black undercarriages and auto wiring and pipes. It's watertight seal is perfect for Koi Ponds or waterfalls and it is safe to be used around Koi Fish. It has premium adhesion abilities to most construction materials including wood, metal, masonry, glass and most plastic outdoor weather conditions and typical auto vibrations won't harm the seal.
Traditionally, there have only been two choices: Bead application and spray application. Some one-component polyurethane materials are easy to apply but are not designed for spraying. For sealing joints, seams or cracks, a one-component foam or canister sealant has been successfully used for 40 years. Projects that require a two-component foam kit are usually more complicated and expensive. While bead application has been effective solution, it is not as effective as a spray application.
Bead applications must often be re-sealed over time and do not penetrate all of the deep surface cracks gaps and crevices, or microscopic areas that are difficult to see or reach. Spray sealant applications expand sealing cracks and crevices deeply and thoroughly when applied correctly. This means that spray applications are more effective, and projects are not likely to require any repeat application. Another property of spray sealants and is that they cure upon reaction--much faster than the bead method. Therefore, surfaces can be restored for use quickly.
