BASF Expands Certified Biomass-balanced Additives Portfolio for Architectural Coatings

BASF is expanding its certified biomass balance (BMB) portfolio of additives for architectural coatings with the introduction of Dispex AA 4145 MB, Rheovis PU 1333 MB and Rheovis HS 1169 MB. Certified according to the REDcert² standard, these new additives support coating manufacturers in reducing the product carbon footprint* (PCF) of their formulations compared with formulations based on the respective conventional BASF additives, while delivering the same high level of performance.

The BMB** offerings contribute to a reduction in fossil feedstock demand: At the beginning of the value chain, fossil-based raw materials are replaced by certified renewable resources, and a corresponding amount of renewable content is attributed to the product according to a mass balance approach. The resulting BMB product is independently certified according to REDcert² and has the same properties as the conventionally produced product. According to BASF’s PCF methodology, the BMB-certified products offer a reduced product carbon footprint compared with the conventional BASF product.

“With the introduction of these biomass-balanced products, BASF is empowering coatings manufacturers to reduce carbon footprint without reformulation challenges,” said Sylvain Huguenard, Global Vice President, Additives at BASF. “Especially in interior architectural applications, where sustainability expectations are rising, our solutions help customers pursue carbon-footprint reduction targets while maintaining performance.

In architectural coatings, Dispex^® AA 4145 MB supports optimized pigment wetting for high-quality finishes, while Rheovis^® PU 1333 MB and Rheovis^® HS 1169 MB provide controlled rheology and application behavior across a wide range of formulations.

The new products are available globally and are supported by BASF’s technical expertise to ensure easy integration into existing systems.

^*Product carbon footprint (PCF): Sum of greenhouse gas emissions and removals of one or more selected process(es) in a product system, expressed as CO₂ equivalents and based on the selected stages or processes within the life cycle – cf. ISO 14067:2018.

^**BMB: For a biomass-balanced product, BASF replaces 100% of the fossil raw materials required to produce the product with renewable resources in its Verbund production setup. The renewable carbon cannot be physically identified in the final product, but the renewable share is fully attributed to it based on an externally certified mass balance approach. The basic definitions of chain of custody models including mass balance are defined by ISO standard 22095.
