Todol Products, Inc. has introduced the Duo-Fill 400 Two-Part Urethane Foam Sealant, designed for plugging and sealing applications where rapid expansion and fast curing are required to quickly stop flowing water. Packaged in a “can-inside-a-can” for field use, this expanding, closed-cell foam sealant mixes directly in the actuator head of the rigid 9-inch dispensing tube, which permits visual quality control.

This product eliminates the need for dispensing guns, hoses and connections, and adheres well to most construction materials. Providing a chemical cure in one minute that is unaffected by weather, the 13 oz., two-part can-inside-a-can expands to 3.5 gallons of foam sealant.
