RhéologieIndex. décimale : 667.9 Revêtements et enduits Résumé : Rheology is always a major concern when you are dealing with water-borne paints and coatings. One of the key sheds involved in formulating them is adjusting the flow, spray and rolling behaviour so that it is juste right. In this overview, we take a look at various low-shear thickeners.

Revêtements organiquesIndex. décimale : 667.9 Revêtements et enduits Résumé : Environmental pressures are driving a change from water-borne epoxy systems using cosolvents to systems that comply with strict VOC reduction targets. Water-borne systems without co-solvents often face drying and film-forming challenges. However, a novel epoxy resin dispersion seeks to address market needs and offer formulators high performance. Note de contenu : - Drying and film formation difficult without cosolvents
- High performance without cosolvent
- Reduced drying time
- Good corrosion resistance for steel and aluminium
- Rapid hardness on concrete

Vernis -- Propriétés mécaniquesIndex. décimale : 667.9 Revêtements et enduits Résumé : Innovation and product development in the coatings industry is being driven by efforts to lower the levels of volatile organic compounds in organic coatings and by growing concern about the adverse effects of harmful, toxic coating components on health. The standard industrial technology for high-performance ambient-to-low-stoving coatings on metal, wood and plastic substrates utilises solvent-borne 2-pack isocyanate binders. The switchover to 2-pack water-borne systems has been hampered by the blistering caused by the reaction of isocyanates with water - until now.
Note de contenu : - Popping
