More features

• 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 Quart Kit; Consists of 1 pint of Part A and 1 pint of Part B and produces 1.25 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
