## Description

Flotation Foam is a polyurethane two-part foam that blends evenly and pours into place to provide soundproofing, insulation and extra buoyancy. 2 lbs. Density. Buoyancy range is 100-120 lbs/quarts. 470-600 lbs/gallon 2 lb foam is recommended for airgap filling in unstructural applications. They can be poured under the deck or in a cavity and require lightweight buoyancy foam to provide buoyancy. This foam is tested in accordance with US Coast Guard Regulations # 33 CFR 183.114.

## Features

- Flotation Foam is a polyurethane two-part foam that blends evenly and pours into place to provide soundproofing, insulation and extra buoyancy
- This expandable foam is recommended for airgap filling in unstructural applications. They can be poured under the deck or in a cavity and require lightweight buoyancy foam to provide buoyancy

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?**

**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.
