| Résumé : |
Over the course of a human lifespan, it is estimated that 90% of that time is spent indoors. As people want to live in healthier indoor surroundings, they increasingly demand water-based paints that are free from air pollutants, hazardous substances and allergens. For consumers, it can be difficult to keep track of the different critical substances, therefore they rely on ecolabels in their buying decisions.
With currently available raw materials and additives, it is no easy task for a paint formulator to develop a high-quality paint that offers performance advantages, is easy-to-use and at the same time fulfils the stringent ecolabel criteria. Formulators therefore consider not only function but also environmental profile when it comes to selecting paint ingredients. Additives should be multifunctional and universally applicable in order to reduce formulation complexity, raw material handling and logistics costs. In addition, they need to comply with regulatory requirements, safety and environmentally-relevant aspects.
This article introduces a novel, sugar-based amine that was developed specifically for use as a multifunctional performance additive in eco-friendly, water-based paints. The application and performance profile are discussed in detail in comparison to common neutralizing agents on the market. |
