| Résumé : |
In recent years voluntary and mandatory schemes have been put in place to improve indoor air quality.
Over the past few years, several global voluntary and mandatory schemes have been introduced to improve indoor air quality by limiting emissions from materials. In many cases it is not feasible or desirable to lower the overall emissions of a coating by simply reducing or completely removing the coalescents present in the formulation as this will have a negative effect on the application, performance and quality of the paint.
Eastman is now offering an enhanced coalescent portfolio to provide the coatings formulator with more options for designing a range of formulations from traditional coalesced coating systems to the latest low emission coatings. While many paints that meet the highest emission standards can be formulated with traditional coalescents, adding a low emission coalescent to Eastman's portfolio allows formulators options for transitioning away from volatile to non-volatile coalescents when required. Rather than spending resources and lime re-formulating paints based on low Tg binders, traditional volatile coalescents can simply be replaced or used in combination with, new low- or non-emitting coalescents.
The poor reproducibility of emission testing is well known within the industry. Formulators often choose to send their samples to more than one external laboratory to validate their emission results. The poor reproducibility can lead to unnecessary reformulation work and further costs associated with re-testing paint samples at more than one accredited test laboratory. No matter how poor the reproducibility of the testing, formulators who opt to formulate with Optifilm enhancer 400, have the reassurance that the contribution of this low emitting coalescent to the emission profile of the paint is always negligible.
Improving indoor air quality and lowering emissions from indoor paints, particularly wall and ceiling paints, is a major challenge for the coatings industry and designing a paint system that can conform to these schemes has become increasingly challenging. |
