Certified biomass-balanced additives for architectural coatings by BASF
Last update on Jul 14, 2026
Coating manufacturers looking to lower the carbon footprint of architectural coatings often face a challenge. Reducing fossil-based content can require reformulation or involve compromises in product performance.
To address this, BASF has expanded its certified biomass balance (BMB) portfolio with Dispex® AA 4145 MB, Rheovis® PU 1333 MB, and Rheovis® HS 1169 MB. Certified according to the REDcert² standard, these additives help reduce the product carbon footprint compared with their conventional counterparts while delivering the same performance.

Reduce carbon footprint without reformulation challenges
According to the company, 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.
According to the company, in architectural coatings, Dispex® AA 4145 MB supports optimized pigment wetting for high-quality finishes. 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.
