EternaBond WebSeal Sealant Tape
EternaBond WebSeal leak repair tape has very high flexibility and a woven polyester backing that works well for roof repair, gutter repair, and ductwork. WebSeal comes in 50 foot rolls with widths of 4", 6" or 8". It is compatible with a number of different types of surface materials and the high flexibility allows it to work around almost any object. It creates a liquid tight seal and has a thickness of 30 mil. Like other EternaBond sealant tape, WebSeal has a silicone lining on the adhesive side to keep it from sticking to other surfaces before application. WebSeal also has a shelf life of up to 5 years.
