BASF Enhances Architectural Coatings Portfolio with Biomass-Balanced Additives

BASF has expanded its certified biomass-balanced (BMB) portfolio for architectural coatings with the introduction of three new additives—Dispex® AA 4145 MB, Rheovis® PU 1333 MB and Rheovis® HS 1169 MB. Certified under the REDcert² standard, the new products are designed to help coatings manufacturers reduce the product carbon footprint (PCF) of their formulations while delivering the same performance as their conventional BASF counterparts. The launch forms part of the company's strategy to support the coatings industry's transition toward more sustainable and lower-carbon products without compromising quality or processing performance.

The new additives are produced using BASF's biomass balance approach, in which certified renewable raw materials replace fossil-based feedstocks at the beginning of the production process. An equivalent amount of renewable content is then allocated to the final product through a certified mass balance system. According to BASF, the resulting additives retain the same chemical composition, specifications and application properties as conventionally manufactured products while offering a lower product carbon footprint. The products are independently certified under the REDcert² standard, providing traceability and verification of the renewable feedstock allocation.

“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.

Designed for architectural coatings, Dispex® AA 4145 MB enhances pigment wetting and dispersion, enabling manufacturers to achieve high-quality finishes with improved color development and surface appearance. Meanwhile, Rheovis® PU 1333 MB and Rheovis® HS 1169 MB are formulated to provide controlled rheology, ensuring consistent viscosity, application behavior and film build across a broad range of coating formulations. BASF noted that the additives enable manufacturers to develop low-emission coating systems without the need for reformulation, helping customers transition to more sustainable products while maintaining established production processes.

The company added that the new biomass-balanced additives are available globally and are supported by BASF's technical service teams to ensure seamless integration into existing coating formulations and manufacturing processes. By expanding its BMB additives portfolio, BASF aims to help coatings producers reduce reliance on fossil resources, lower the carbon footprint of finished products and meet growing market demand for sustainable building and construction materials.
