A new bio-based polyol than can enhance the resistance of indoor floorings has been launched by BASF (Ludwigshafen / Germany; www.basf.com).

The complex polyether-ester polyol is produced from renewable materials and contains no volatile organic compounds (VOCs), making it highly suitable for VOC-free 2K PU applications. As a result, the resin greatly contributes to the production of more sustainable coatings with particularly high levels of stability and durability, said BASF.

“Solvermol” 830 can be used for industrial flooring systems, coatings exposed to potable water and semi-structural adhesives. As well as excellent abrasion and impact resistance, the polyol shows outstanding flexibility even at low temperatures which prevents cracks from spreading in the substrate.

High filling levels and low processing viscosity help to lower the overall cost of formulations. In addition, despite its extended processing time, Solvermol 830 can be walked on after just one day, reducing downtimes and costs.

BASF also offers additives that can be combined with Solvermol 830, as well as suitable cross-linkers and co-binders to achieve the required mechanical properties.
