## Features

- ✅ High-Strength & Durable: This two-part liquid pour-foam component system produces foam when Parts A and B are mixed together. It does not contain any CFC blowing agents and has a closed-cell structure that resists water absorption for many years. Once cured, the urethane flotation foam stays intact against solvents, oil, gasoline, fresh or salt water, and features a 95%–98% closed-cell structure with a 4-lb density.
- ✅ Easy to Mix & Apply: Just mix at a simple 1:1 ratio to ensure 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. It’s fully cured and ready for use in just a few hours.
- ✅ Excellent Insulation & Soundproofing: 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.
- ✅ Various Applications: Ideal 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.
- ✅ Versatile & Adaptable: This 2-part liquid pour-foam system can be poured in multiple layers with excellent bonding between them. Once fully cured, the foam can be coated with polyester, epoxy, or vinyl ester resins without melting. Shaping is easy once cured.

## Questions & Answers

**Q: What color is the expanded product?**
A: It is a light beige color.  I am using it floatation and painted the exposed surface blue (just because I had blue spray paint and thought it might protect the surface, probably not needed though)

**Q: What can you use to break this down?  I have some spillover i want to remove.   Acetone?**
A: Yes, that's what I used and it worked fine.

**Q: If mixing by weight is says “100 parts 115parts”??? Is that 100 parts of the A and 115 parts of the B?**
A: I do equal amounts

**Q: As it expands, does it exert a lot of force on mold it is in?**
A: By my experience it does not. But you will need couple of vents to release pressure and overflow. It does heat up and you can feel it.
