So far, most of our comparisons of FST Conduit Sealant to typical low-cost canned foam have focused on canned foam's inferiority even in an ideal, fully cured state. In the real world, ideal conditions are not an everyday occurrence. You should be aware of another key advantage to FST. Two-part versus one-part foam technology. FST is a two-part compound that, when mixed together in a static mixing nozzle, generates a chemical reaction that initiates the expansion and hardening of the foam plug. This reaction results in a fast and consistent cure and ensures a strong final conduit seal. FST sealant cures within 15-20 minutes after injection, depending on air temperature. Single-part foams are much slower and their cure rate is much less consistent, as these products must draw moisture from the ambient air to initiate expansion of the foam. Single-part foams can take up to 24 hours to cure, and many times the interior of the seal remains soft or contains pockets of un-reacted resin. Once the exterior portions of one-part foam exposed directly to the air harden, the moisture needed to cure the interior of the foam cannot pass through this solidified crust. No one likes biting into an undercooked pancake and encountering a pocket of gooey batter. Similarly, your customers don't want pockets of gooey, ineffective resin in their conduit systems. They want FST, the two-part technology that cures quickly throughout the entire seal to guarantee a solid, homogeneous foam block ... regardless of the "cook" or the "kitchen." |
