WrapFill 811

WrapFill 811™ is a unique blend of liquid polymers and proprietary curing agents that can displace water from surfaces to make a permanent bond. The formulation is free of solvents to ensure maximum performance. Kevlar™* fibers are integrated for stiffness and viscosity management to assure application even in adverse conditions.

WrapFill 811™ is a filler putty designed for use in ducts where there is loss of thickness. WrapFill 811™ is capable of displacing wet surfaces to establish a permanent bond to the substrate. The standard base color is WHITE which is mixed in equal quantities with the BLACK curative. The result of this mixture is a GRAY color. This system is not regulated by the US Transportation Agency, USDOT, AITA and IMO. * Kevlar is a registered trademark of DuPont.
