Dreyplas to Present Additive for Powder Coating and WB Spray Coating at ECS 2025
Last update on Mar 10, 2025
Dreyplas will be presenting application properties and possibilities of Mipelon™ at stand 4A-527 at the European Coating Show 2025, to take place in Nuremberg from 25 to 27 March. The company distributes the product from in Europe and is also working with customers to develop solutions for optimizing tribological properties with UHMW-PE instead of PTFE.Environmentally Friendly Alternative to PTFE
Mipelon™ is a fine powder whose spherical particles consist of ultra-high molecular weight polyethylene (UHMW-PE). As an additive, it significantly improves the sliding properties, abrasion resistance and chemical resistance of paints and coatings. Typical applications include electrostatic powder coating, water and solvent-based spray coating and dip coating. Mipelon™ thus offers a high-performance, environmentally friendly alternative to PTFE, which is affected by the PFAS debate.
Mipelon™ is also characterized by its high chemical resistance to acids, alkalis and organic chemicals. In addition, it absorbs virtually no water or moisture. Most grades are suitable for food contact applications in accordance with EU and US legislation.
Unlike PE powder, which is also used for this purpose, Mipelon™ does not tend to swell even at high temperatures and retains its shape and function. Compared to PTFE, it has a lower coefficient of sliding friction and better abrasion resistance at the same dosage, which makes it economical to use. The lower melting temperature of around 135 °C can have a limiting effect when substituting PTFE.
The molecular weight of Mipelon™ is up to 2 million g/mol. The average size (D50) of the spherical particles is only 10 µm for the PM-200 type, which is currently the smallest size in this product group worldwide. For XM-220 the D50 value is 30 µm and 65 µm for XM-330. In the paint and coatings industry the finer powder grades are mainly used. New types with a D50 value of less than 5 µm and around 6 µm are currently under development. The latter is already available for sample purposes. Commercial availability is planned for the end of 2025.
