25.05.2025 Activating paint surface for better indoor air quality Back Tools Bookmark Share Driven by environmental, health, and safety concerns, coatings technologies have undergone a dramatic shift in the past few decades driven by the reduction of VOCs and other hazardous materials in coating formulations. The continuous development and improvement of waterborne technologies has enabled many solvent-based systems to be replaced with waterborne chemistries that contain significantly lower VOC content than their solvent-based counterparts. VOC levels have been pushed even lower by the development of low-VOC and zero-VOC water-based formulations. A continuation of this trend emerging in the global coatings industry has been focused on the development of functional coatings that not only limit emissions of VOCs into the environment but actively extract and remove VOCs that have originated from other sources. A functional coating with VOC remediation capability could improve indoor air quality and provide a means to scavenge VOC emissions from sources that have proven to be more challenging to address. This investigation is based on two different methodologies. In a first part, ISO 16000-23 European standard has been used as an initial demonstration of the formaldehyde scavenging efficiency of a conventional zero-VOC decorative paint containing tris (hydroxymethyl) aminomethane and 2-amino-2-ethyl-1,3-propanediol. Even if extended to 6 weeks, this dynamic test is not able to determine the real full scavenging capacity of the studied material. A new method has been developed with the intend to experimentally measure the full capacity of adsorption, and also to test several pollutants present in indoor environment over formaldehyde, enabling to characterize the scavenging versatility of these additives.
