Expands to Fill Voids Increases Buoyancy
Fill boat cavities, pontoons and floating dock blocks. Make your own buoy markers.
Just mix and pour this low-viscosity polyurethane foam to fill cavities and increase buoyancy.
As an insulating foam it is excellent for applications requiring a liquid applied product that will flow into recesses and hard-to-fill voids. Examples are structural laminates, freezers, coolers, truck bodies.
Uses a 1:1 mixing ratio, making it ideal for small quantity hand mixing and conventional dispensing equipment.
Provides flotation, insulation, and fills gaps
Fast reaction formula allows approximately 15 to 20 seconds for mixing and pouring
Rise time is 2-3/4 to 3-1/4 minutes
