## Description

Fiberglass Supply Depot 2 Lb Density Expanding Pour Foam, 2 Part Polyurethane Closed Cell Liquid Foam for Boat and Dock Flotation, Soundproofing, Filling Voids, and Insulation (Quart Kit): desertcart.com: Industrial & Scientific

## 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

## Questions & Answers

**Q: what is the storage shelf life?**
A: As long as it is in a cool dry place it should last about 6 months.

**Q: Is the blowing agent water or other?  Do you have a K value for the foam?**
A: There is no blowing agent. Water will cause the foam to not rise.

**Q: what is the proper storage temperature? pre mix.**
A: Stored in unopened, containers at temperatures between 10 - 32°C (50
- 90°F).

**Q: Can you spray these chemicals? step 1 in one bottle, step 2 in the second bottle..**
A: They do have special guns to be able to spray but if you tried to mix the two together and then try to spray you would have problems as this expands too fast.
