Evonik to introduce new hybrid crosslinker at ECS 2019
Evonik Hall 7A Stand 323
Evonik announced that it will introduce the latest addition to its Vestanat product family at the European Coatings Show (ECS) 2019. As a constituent of one-component clear coatings, Vestanat EP-EF 201 silane/polyurethane hybrid crosslinker is said to impart a particularly sophisticated visual appearance to metal and wood coatings.
According to the manufacturer, the environmentally friendly crosslinker contains only very small amounts of volatile organic compounds (VOC). It is suitable for both professional use and do-it-yourself applications. Coatings formulated with the new product can be very easily processed: They cure even at room temperature and are dry after just 1 h, thus allowing fast downstream processing.
“Environmental aspects such as low solvent content are playing an increasingly important role in consumers’ purchasing decisions. With Vestanat EP-EF 201 we are helping to meet our customers’ requests in this regard, enabling them to formulate especially high-performance, but low-emission, coatings,” said Dr. Guido Streukens, head of Vestanat Technical Service.
At the trade show, Evonik will also provide visitors with information about other products in the Vestanat EF/MF family. All of these combine the advantages of silane chemistry with those of polyurethanes – and so provide excellent scratch resistance with simultaneous retention of polyurethane properties in coatings, said the company.
The optimal crosslinker is selected from the various options depending on the substrate and curing temperature. Vestanat EP-MF 203 and Vestanat EP-MF 204 are solvent-free, ready-to-use hybrid crosslinkers that cure even at room temperature. They can be used as moisture-curing binders or in combination with suitable co-binders such as acrylic resins. The proven unaccelerated crosslinkers of the Vestanat EP-M grade, on the other hand, are used when temperatures of 80 °C to 160 °C are reached during the coating process.
Further information will be provided in the presentation “Si/PUR hybrid crosslinkers: one step ahead of high performance” by Tobias Unkelhäußer, Senior Manager Technical Service, between 12:10 h and 12:30 h on 19 March 2019 at stand 544 in hall 9 at the ECS trade show.
