The improved product is now claimed to produce lighter weight composites and is ideal for mass transit applications. This resin now has a simpler-to-use one-part system and is claimed to perform at a higher level than other products on the market.
Firepel K120-MTA is designed for the hand lay-up and spray-up composite manufacturing processes.

K120-MTA is a unique product and outperforms every other resin on the market. It utilizes proprietary halogen-free technologies to achieve the highest fire-retardant and low-smoke characteristics possible. And because its excellent performance is achieved without ATH, K120-MTA has a much lower specific gravity, which makes it easier to process than traditional systems. |

AOC adds that unlike conventional low smoke resins, K120-MTA achieves its fire performance through a proprietary intumescent mechanism. As a result, K120-MTA offers excellent wet out and spray characteristics, crack resistance, and low density. This combination of properties produces fire-retardant and low-smoke composites that are lighter weight, stronger and easier to fabricate than those made from mineral-filled resins.
The increasing need to reduce the weight of vehicles will continue to drive the demand for composites’ use in buses, trains and other mass transit vehicles. Parts using K120-MTA have a potential weight savings of up to 30% compared to standard composites using antimony or alumina trihydrate (ATH).
The mechanical properties of Firepel K120-MTA include:
