Duct Seal Putty is used primarily by the building and specifically by the electrical trade to seal around electrical boxes, flashings, and service mast entries, etc. It can be shaped by hand to any form and reused if necessary. It has countless other applications in the refrigeration, heating and cooling, plumbing, and metal fabrication fields as well as being an excellent general purpose sealant around the home. It may be painted immediately after application and will not bleed through the dry paint. Contains a pigment that serves as a UV stabilizer. The pigment absorbs the UV light and transfers it to heat, lengthening the life of the polymer bonds that make up the sealant. Anti-oxidant inhibitors are present that also help prevent UV degradation. The base polymers used are very stable against UV effects so there are inherent natural properties for this resistance as well.
