BASF, a global leader in the supply of additives to the coatings industry, has completed the transition to bio-based Ethyl Acrylate (EA) for its Rheovis range manufactured at Ludwigshafen and Bradford sites. Now, the Rheovis range has a ¹⁴C-traceable biogenic content of up to 35% according to the ASTM D6866-18 analytical standard and a reduced Product Carbon Footprint (PCF) of up to 30% compared to versions based on fossil feedstock. This development underlines BASF’s commitment to support customers in achieving their sustainability goals. The chemical composition and technical specifications of the new bio-based products remain unchanged.

This feedstock switch underlines BASF Additives’ commitment to enable formulators to complete their green transition while ensuring supply reliability and efficiency. BASF’s optimized process and Verbund concept are key levers to ensure further reduction of our Product Carbon Footprint (PCF).

BASF’s recently launched HASE rheology modifiers, the biocide-free Rheovis HS 1101 and Rheovis HS 1153 have been intentionally developed with this higher biogenic content, providing customers with improved performance and sustainability features. In addition to the ¹⁴C-traceable biobased content, the BASF Biomass Balance (BMB) approach can be applied to further reduce the Product Carbon Footprint (PCF) of a product.

BASF’s Rheovis rheology modifiers are specialized additives used in water-based coating systems, with significant applications in the automotive industry. These products, including non-ionic associative (HEUR/HMPE), anionic associative (HASE), and non-associative (ASE) thickeners, are designed to control viscosity and enhance the performance of automotive coatings.
