2 Lb Density Expanding Pour Foam for Boat and Dock Flotation and Insulation (1 Gallon Kit)

Polyurethane 2-part foam, known as Flotation Foam, is a versatile product that can be used for soundproofing, insulation, or providing extra buoyancy when mixed in equal parts and poured in place. This expandable foam is recommended for void filling in nonstructural applications, such as pouring it underneath decks and inside cavities where a lightweight flotation foam is needed to provide buoyancy.

The 2# Density polyurethane flotation Foam 1 Gallon Kit consists of 1/2 gallon of Part A and 1/2 gallon of Part B, which produces 5 cubic feet of foam once fully cured. This foam can be laminated over with any type of polyester, epoxy, or vinyl ester resin without melting.

It is important to note that the expansion rates and times of this foam are temperature-critical. Temperatures below 75° F will lower the expansion rate, requiring the use of more foam. The ideal working temperature is 75° to 80° F or above. Accurate measuring of these products is extremely critical, as is the working time before foaming, which is approximately 45 seconds, and the time before full expansion, which is around 5 minutes.

The versatility of Flotation Foam makes it a valuable product for a variety of applications, from soundproofing and insulation to providing buoyancy in nonstructural settings. Its ability to be laminated over with various resins without melting further enhances its usefulness, making it a viable option for a range of construction and DIY projects.
