## Description

True Composites 4lb Boat Pour Foam Kit, 4 Gallon | Closed-cell foam for flotation, buoyancy, insulation & filling.: desertcart.com: Industrial & Scientific

## Features

- ✅ Remarkable Strength: This two-part liquid pour-foam system produces foam when Parts A and B are mixed together. It does not contain any CFC blowing agents and features a closed-cell structure that resists water absorption for years. Once cured, the urethane flotation foam stays intact against solvents, oil, gasoline, fresh or salt water, and benefits from a 95%–98% closed-cell structure with a 4-lb density.
- ✅ Simple to Mix and Use: Pour Foam Series systems make hand or machine mixing easy and produce a uniform product with outstanding cell structure. Just mix at a 1:1 ratio for even distribution and the strongest foam possible. This fast-acting formula allows about twenty seconds for mixing and pouring, and the foam sets in place within 10 minutes. Fully cured and ready for use in just a few hours.
- ✅ Perfect Expanding Foam to add Insulation: The high-density foam protects boat pipes in colder temperatures and blocks sound, making it ideal for filling dock floats or boat parts for soundproofing and insulation.
- ✅ Multifunctional: Great for casting, carving, sculpture, plug making, sign making, flotation for boats and buoys, floating decoys, part fabrication, replicating wooden parts, rigidifying, structural support and more.
- ✅ 2-Part Liquid Pour Foam Component System: This product can be poured in multiple layers with excellent bonding between layers. Once fully cured, the foam can be coated with polyester, epoxy, or vinyl ester resins without melting. Shaping is simple once cured.
