Polyester Powder Resin Manufacturers Sector Group (PPRM)

Uses and properties

Polyester powder coatings are based on a polyester resin which reacts with a hardener (cross-linking agent), completed with pigments and an additive package. The process results in a finely ground powder which is then sprayed onto the substrate surface with electrostatic equipment and baked in an oven, creating a fully cured smooth and durable coating.

Polyester powder coatings are used in industrial applications for both decorative and protective uses on profiles for buildings, agricultural machinery, white goods such as fridges, garden and leisure-equipment and many other applications. The thickness of a polyester powder coating is usually between 40 and 80 µm.  While typically used on metal substrates, new developments are opening the use of powder coatings to other substrates such as wood and plastics.

Powder coatings being solid materials enable the preparation of VOC (Volatile Organic Compound) free coatings.  One of the main advantages of powder coatings is the increased application efficiency with up to 98% yield through the use of appropriate equipment.  Polyester powders have very good edge covering, mechanicals, flow properties, gloss and colour retention and excellent outdoor durability.

Joint SRM/PPRM Carbon Footprint Study

Commissioned by the Cefic associations PPRM (Polyester Powder Resin Manufacturers) and SRM (Solvent based Resin Manufacturers), Denkstatt GmbH Austria has performed a study with the goal to create reliable and credible average carbon footprint data (CFP) for a series of product families manufactured by the members of PPRM and SRM.

“Cradle to gate” carbon footprint averages were calculated for different grades of polyester resins, alkyd resins, acrylic resins, polyurethane resins and amino resins.
For the modelling the emphasis was placed on the raw materials, solvents, auxiliary materials, by-products and process data like energy, process specific emissions, waste and transport. For further information please contact Alice Salmon at Cefic.
