RhéologieIndex. décimale : 667.9 Revêtements et enduits Résumé : There is a strong trend towards minerai paints, since these formulations enable a healthier room ciimate. In terms of processability and ageing stability dispersion paints used to surpass them. The availability of a new additives for formulat-ing minerai paints now helps manufacturers overcome those drawbacks. Note de contenu : - Preservative-free paints are growing in importance
- New additive for eco-label compliance
- Low yield stress and viscosity in comparison testing
- Optimised rheology of preservative-free paints
- No adverse impact on tinting or breathability
- Dual function extends formulation scope

RhéologieIndex. décimale : 667.9 Revêtements et enduits Résumé : Additives have an influence on the drying process of water-based paints by affecting the Brownian motion of particles.
The additive-dependent viscosity changes help to manipulate effects such as run-off or flow during drying of water-based paints. In addition, a linear correlation between the open time (according to ASTM D7488) and the 2nd decrease in Brownian motion was found. Possibly, with the help of the correlation, the classical ASTM D7488 method can be replaced by ASII measurements (ASII: Adaptive Speckle Imaging Interferometry).Note de contenu : - Effective methods for measuring the influence of additives

Revêtements en bâtiment:Peinture en bâtimentIndex. décimale : 667.9 Revêtements et enduits Résumé : Façade paint can leach when water condenses on freshly dried painted walls, leaving behind shiny vertical "snail trails" that alter and deteriorate the façade's appearance. To date, predicting a paint formulation's tendency towards leaching is difficult, because the phenomenon is poorly understood, and no standardised analytical methods exist. A newly-developed test method can mimic leaching conditions and help in studying the influence of paint ingredients on the occurrence of snail trails. In addiction, we devised a new polymeric dispersant that is resistant to leaching to aid formulators. Note de contenu : - Novel test methods hepl to track down the source of the snail trails
- Qualitative test - does the paint formulation develop snail trails?
- Illustrating the pratical use of the test: various binders in a paint formulation
- Quantitative test: finding the root cause of leaching in a paint

Stabilité au stockageIndex. décimale : 667.9 Revêtements et enduits Résumé : Despite only being used in small quantities in water-based paints, neutralising agents can have a significant impact. They regulate the pH value and make a positive contribution to the storage stability of the paint by reducing the interaction between the paint ingredients. Compliance with health and environmental requirements, such as being VOC/SVOC-free and hazard label-free, make these neutralising agents particularly attractive for ecolabel-certified paints.

- Ecolabels restrict content
- Sugar-based additive offers sustainability benefits being a renewable material
- Neutralising agents put to the test

Revêtements en phase aqueuse -- Additifs:Peinture en phase aqueuse -- AdditifsIndex. décimale : 667.9 Revêtements et enduits Résumé : There are various neutralising agents available to the paint industry. The ost common neutralising agents on the market are standard products, such as caustic soda (NaOH) and ammonia or the muttifunctional additive 2-Amino-2- Methylpropan-1-ol (AMP).
Clariant recently introduced a sugar¬based speciality amine (Glucamine) developed specifically for use as a multifunctional performance additive in eco-friendly, water-based paints. In order to create a comprehensive assessment of these neutralising agents, this article considers environmental, health and safety aspects with the comparison of performance characteristics.Note de contenu : - How sustainable are neutralising agents ?
