 FST-250 |
We promised more information on the new Polywater FST-250 Foam Duct Sealant "caulking-gun" package. First, about that caulking gun. Be aware that most hardware stores carry them (Polywater does too: cat #FST-TOOL250), but these are not the $1.59 cheapies. The more expensive high-ratio tools work best. The cheaper tools may suffice for low-volume usage, but dispensing the foam from the cartridge and through the restriction of the mixing nozzle requires exertion that over time may frustrate customers, and can cause the tool to fail. The beefier high-ratio tool eases dispensing and is recommended for regular use. Second, a key target of this new package should be customers using "canned foam." Canned foams are generally inexpensive and very convenient. You won't compete there. Their drawback is the quality of the foam. Typically, these are open-cell foams. They foam up quickly, but many of the bubbles burst. Also, the cell walls on many of the bubbles that don't burst initially do so later under pressure. These so-called open cells weaken the structure of the foam and allow water and gases to weave their way through, eventually negating any duct blocking effect. Open-cell foams do not hold water or gas, and are ineffective duct blocks. FST, on the other hand, is a robust closed-cell foam that out-performs canned foam in all ways. The FST-250, with its more familiar and inexpensive tool (relative to the FST-180) may help you win over more customers willing to pay a bit more for a product that actually works. |
