Duo-Fill 400 two-part urethane foam sealant
The Duo-Fill 400 two-part urethane foam sealant comes in a single convenient can-inside-a-can with a long dispensing tube that reaches deep into conduits and holes. This expanding closed-cell foam sealant is mixed directly in the actuator head of the rigid 9-in. dispensing tube, which permits visual quality control. It is designed for plugging and sealing applications where rapid expansion and fast curing are required to quickly stop flowing water. It provides a chemical cure in 1 min that is unaffected by weather. The contents of the 13-oz can dynamically expand to 3.5 gal of foam sealant.
