## Description

Fiberglass Supply Depot Pounds. Density Expansion Foam, 2 Part PU Closed Cell Liquid Foam for Boats, Dock Floating, Sculpture, Acoustic Insulation, Fillimen : desertcart.ae: Industrial & Scientific

## Features

- Flotation Foam is a 2-part polyurethane foam that, when mixed in equal parts and put in place, this foam will be soundproof, insulate or provide extra buoyancy.
- 6 Pounds 1 Gallon Density Polyurethane Flotation Foam Kit; Consists of 1/2 Gallon Part A and 1/2 Gallon Part B and produces 1.5 cubic feet.
- Once fully cured, this foam can be laminated with any type of polyester, epoxy or vinyl ester resin without melting.
- The 6LB density also works well in floating bait or taxidermy applications, as well as many other sculpting, casting, carving and other filling applications.
- All provided expansion rates and times are temperature critical. Temperatures below 75° F will decrease the expansion rate, therefore requiring more foam. Ideal working temperature is 75° to 80° F or higher. Accurate measurement of these products is extremely critical. Working time before foaming: approx. 45 seconds Time before full expansion: approx. 5 minutes
