Powder coatings
Resins for powder systems
For thermosetting systems, Arkema, with its Reafree® brand, offers a range of carboxylated and hydroxylated polyester resins suitable for pure polyester and hybrid systems (Polyester-Epoxy). Hybrids offer very good performance mainly for Interior applications, while pure polyesters are suitable for both Interior, (Industrial grades) and exterior applications (Architectural & super durable).
Among thermoplastic systems, Arkema’s offer includes:
Rilsan®, Advanced bio-circular polyamide 11 that delivers toughness, flexibility and chemical resistance, but also other High Performance Polymers such as Kynar® (PVDF), Pebax® (TPE-Thermoplastic Elastomers) or Kepstan® (PEKK)
Additives for powder systems
With Crayvallac® additives, Arkema provides additives for many powder systems including surface modifiers and flow and levelling agents.
Innovative materials for a sustainable world
Arkema is committed to developing a more sustainable world with an innovation strategy focused on solutions that contribute to the sustainability of the finished coating. Powder coatings are 100% solid systems, meaning there is no liquid, no solvent (even water), and no hazardous volatile components, making this technology one of the best sustainable options on the coating market.
For thermosetting systems, select Reafree® products can help formulators lower cure temperatures in order to reduce energy consumption or speed cure times to improve efficiency. Arkema also offers powder resins for non-metal/heat sensitive substrates.
For thermoplastic systems, the Rilsan® Fine Powders product range is based on polyamide 11, a 100% biobased polymer. This advanced bio-circular material is derived from sustainable castor oil and allows easy recycling of metal.
