2 Lb Density Expanding Pour Foam, 2 Part Polyurethane Closed Cell Liquid Foam for Boat and Dock Flotation, Soundproofing, Filling Voids, and Insulation (2 Gallon Kit)

Flotation Foam is a polyurethane 2 part foam that, when mixed in equal parts and poured in place this foam will soundproof, insulate, or provide extra buoyancy.. This expandable foam is recommended for void filling in nonstructural applications. It can be poured underneath decks and inside cavities where a lightweight flotation foam is needed to provide buoyancy.. 2 Density polyurethane flotation Foam 2 Gallon Kit Consists of 1 gallon of Part A and 1 gallon of Part B and produces 10 cubic feet.. Once fully cured this foam can be laminated over with any type of polyester, epoxy or vinyl ester resin without melting.. All expansion rates and times given are temperature critical. Temperatures below 75 F will lower the expansion rate therefore requiring more foam. Ideal working temperature is 75 to 80 F or above. Accurate measuring of these products is extremely critical. Working time before foaming approx. 45 seconds Time before full expansion approx. 5 minutes.
