“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 in Nuremberg, 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.
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 (176° to 320°) are reached during the coating process.
