| Résumé : |
Amino alcohols based on ANGUS chemistry can assist formulators in creating more environmentally-friendly paints and coatings. Multifunctional additives from ANGUS can be used to create low- and zero-VOC waterborne formulations, as well as low emissive coatings that qualify for green label certification programs. Amino alcohols are also highly effective formaldehyde scavengers that can be used to create functional coatings that improve indoor air quality.The level of hazardous air pollutants can be five times higher in indoor air than outdoor air and chronic exposure to these invisible indoor toxins, such as formaldehyde, can create long-term health problems. An attractive solution to reducing indoor formaldehyde levels is through a chemical remediation or scavenging system, and one of the emerging trends for the effective removal of indoor air contaminants is the use of functional coatings. We demonstrate how the unique functionality of amino alcohols can help improve indoor air quality by providing high-efficiency formaldehyde scavenging performance when used in waterborne architectural paints. Amino alcohol additives are highly effective at low dosages and do not require major reformulation work, enabling the creation of functional coatings to improve indoor air quality. |
