Vernis en phase aqueuseIndex. décimale : 667.9 Revêtements et enduits Résumé : Industry has been moving away from traditional solvent-borne coatings often to water-based systems. Manufacturers also try to provide formulators with cross-linkers and adhesion pro-moters that meet changing and challenging market needs. Isocyanate chemistry is a very useful tool for achieving this goal. The focus is on further reducing or eliminating VOCs, providing flexibility over a full pH range and wherever possible delivering solutions that have minimal impact on health, safety and the environment.

Vernis en phase aqueuseIndex. décimale : 668.5 Parfums et cosmétiques Résumé : Beautiful and healthy nails take on more and more significance for many customers. Thus, when developing new and innovative nail polishes, breathability is a significant factor. In this paper, breathability of nail polishes, which is often referred to as a combination of air/O2 and water vapor permeability, was investigated. For this purpose, two solvent-based nail polish formulations were benchmarked against two water-based nail polish formulations according to DIN-Norm 53122-1 and 53380-3. The data clearly indicate, that water-based nail polish formulations based on Suntran polymer perform considerably better. In combination with Silkgel, the hybrid polymer Silktran is formed, which increases both oxygen and water vapor permeability, making this novel hybrid polymer a unique best-in-class performance product.

Vernis en phase aqueuseIndex. décimale : 667.9 Revêtements et enduits Résumé : The automotive industry has undergone incredible changes by ways of material and process development. Different driving forces behind the development of better and more efficient process have brought dramatic changes over last 100 years.
Number of applied coatings layers has been reduced to 3 layers. The latest development of wet on wet coating technology coating machines automatic cleaning process the time taken for the body painting reduced to 8 hr.
Emission of volatile organic compounds (VOC) is main problem for coating industry considering the fact increase in the solid content which increase covering capacity of coating and decrease in solvent content in solvent borne formula is implemented the relative increase of solid by 20% generated completely new technology i.e. High solid technology.Note de contenu : - VOC REDUCTION DATA FROM YEAR 1965 TO 2005

Vernis en phase aqueuseIndex. décimale : 667.9 Revêtements et enduits Résumé : Cellulose nanocrystals were mixed into an aqueous UV-cured coating formulation in order to improve the mechanical properties of the coating. One of the key aspects in the technology of nanocomposites remains the dispersion of the nanoparticles within the matrix. To quantify the dispersion, efficient methods of characterization are needed. In this study, a new characterization method based on atomic force microscopy (AFM) and backscattering of laser light (He–Ne 632.8 nm) is applied to characterize such nanocomposite coatings. The angular distribution of backscattered light intensity was approximated by Gaussian distribution, and its standard deviation was used for the surface roughness analyses. A strong correlation between surface nano-roughness of coatings and angular distribution (half-width of the angular spread) of backscattered laser light was found. This laser characterization is faster and may be done without direct contact over a wider surface than AFM and may give us an idea about mechanical properties of coatings. This method can advance our fundamental understanding of dispersion of the nanoparticles in coatings and could be of use in quality control in industry.
