AOC Release New High-Performance Resin System for Mass Transit Applications

11 November 2013

The company says Firepel K120-MTA is a one-part, halogen-free system and does not require antimony or aluminum trihydrate (ATH) to achieve fire-retardant properties.

Unlike conventional low-smoke resins, AOC says K120-MTA achieves its fire performance through a proprietary intumescent mechanism. 

As a result, AOC says K120-MTA offers excellent wet-out and spray characteristics, crack resistance, and low density. This unique 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 ATH.

“K120-MTA is a unique product and outperforms every other resin on the market,” says Fletcher Lindberg, Vice President of Marketing for AOC.  “It utilises 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.”
