BASF, the largest chemical producer in the world, launches a new bio-based polyol sold under the name Sovermol. The product is used for manufacturing extremely low-emission two-component polyurethane coatings for interior and exterior applications.
The Germany headquartered company told that it makes indoor floorings, e.g. in industrial warehouses or sports halls, more resistant. As the resin is produced from renewable raw material and contains no volatile organic compound it greatly contributes to the production of more sustainable coatings with particularly high levels of stability and durability.
Due to a specific chemical modification, the complex polyether-ester polyol has excellent water-repellent properties, according to BASF. It exhibits great curing properties, even in challenging curing environments with high humidity and temperature. Due to its high filling levels and low processing viscosity, Sovermol helps to lower the overall cost of a formulation. In addition, the thermoplastic material has a high hardness. Despite the extended processing time, the material can be walked on after one day only, which ensures shorter downtimes and, consequently, lower costs.
The polyol can be used in coatings for industrial floorings, coatings exposed to potable water and semi-structural adhesives. Apart from its excellent abrasion and impact resistance, the product shows good flexibility even at low temperatures, which prevents cracks from spreading in the substrate. It is therefore the ideal solution for durable coatings.
BASF offers coatings producers appropriate high-performance additives that can be combined with Sovermol 830. Furthermore, the company’s portfolio comprises suitable cross-linkers and co-binders that enable customers to achieve the required mechanical properties.
