Silane/Urethane-Hybrid Crosslinkers for Multifunctional, Scratch-Resistant Coatings
A new and versatile family of crosslinkers/binders for high-performance wood coatings has been developed. The innovative technology platform to the -VESTANAT® EP-M crosslinkers combines the benefits of silane chemistry with the performance of polyurethanes, enabling excellent scratch resistance while maintaining urethane properties in coatings. The core building block of this novel approach is 3-isocyanatopropyltrimethoxysilane (IPMS), which allows the freedom to design and create tailor-made binders and crosslinkers.
The resin concept also enables non-isocyanate (NISO) technology, exhibiting and exceeding polyurethane performance. This technology can be realized in one- and two-component coating formulations.
