VernisIndex. décimale : 667.9 Revêtements et enduits Résumé : Siloxane-based additives play a major role in high-quality coating formulations. The use of organo-modified polysiloxanes in surface additives is growing beyond classical applications in wetting agents and defoamers. Due to their unique interfacial activity, modified siloxanes are invaluable ingredients that improve leveling and decrease cratering while producing smooth film surfaces This results in functional surface properties such as slip or easy-to-clean (ETC) effects.

Surfaces -- NettoyageIndex. décimale : 667.9 Revêtements et enduits Résumé : With the increasing use of tactile touch interface and high gloss finish surfaces in various market sectors, including packaging, automotive, appliances, consumer goods and teletronics, the need for an easy-to-clean (E2C) surface property is growing and posing a challenge to designers and coating formulators. As a consequence, investigation of these new functional surfaces has gained increasing interest in technical and scientific literature. Yet, the most effective solutions currently available are quite costly and, consequently, only used in high value components such as touch screen displays.
To overcome this high cost barrier, Cytec introduced its latest development for energy curable coatings, namely Ebecryl 8110 resin for consumer electronics components such as casings etc. This novel and patent-pending UV resin enables paint formulators to develop coatings that meet the overall coating performance requirement (hardness, adhesion, chemical resistance) as well as permanent easy fingerprint removal/easy-to-clean surface property.Note de contenu : - Effect of composition
- Effect of application conditions on E2C performance
- Robustness of the E2C property and benchmarking

Surfaces -- NettoyageIndex. décimale : 667.9 Revêtements et enduits Résumé : The author discusses the market for and development of antimicrobial coatings.
The need for durable and more environmentally friendly solutions for coating materials has been shaping the coatings industry for many years. Consumers from various markets, including the construction trade and automotive manufacturing, want coatings that enhance the resilience of surfaces to stains, dirt, and mildew. However, even with the addition of protectants and decorative paints or lacquers, microbes are still able to adhere to a surface, where they can multiply rapidly. Their uncontrolled growth and spread as a result of contact, environmental conditions or inadequate cleaning (Figure 1) can then lead to unpleasant consequences, including spoilage, stains, nasty odours and a reduction in the usable lifetime of a product due to contamination or biodegradation.
There are a number of treatments that consumers can use to help reduce the growth and spread of microbes on surfaces, and using them regularly is essential. However, standard cleaning products often have limited residual activity, meaning that they stop working once they dry. This can allow surfaces to become quickly re-contaminated by contact or airborne sources, which is a particular concern for high-touch points such as countertops and doors.
Antimicrobial technologies in coatings can help to address these challenges by effectively creating a protective layer that keeps surfaces cleaner and fresher for longer. This 'always on' protection works around the clock to help prevent the growth of microbes on a surface for the lifetime of the coating, without washing or wearing away. For just a minimal cost, this universel lifetime preventative measure provides the perfect complement to standard routine cleaning practices, employing a multi-defence strategy against the growth of microbes to improve overall surface cleanliness.Note de contenu : - A growing market

ZincIndex. décimale : 667.9 Revêtements et enduits Résumé : The surface activity of hot-dip galvanized steel was evaluated after alkaline cleaning by exposing the cleaned specimens in humid supercritical carbon dioxide, followed by extraction and quantification of the formed corrosion products. Different free alkalinities of the cleaning bath were studied to obtain information on the evolution of zinc surface activity at different levels of surface etching. Surface reactivity of uncleaned galvanized steel is restricted and local, with major contributions from grain boundaries and intermetallic particles. Formation of zinc corrosion products took place in uncleaned samples exclusively on and around these sites. Al2O3 removal by alkaline cleaning gradually increased the surface activity. The major increase in surface activity was achieved when increasing the free alkalinity from 0.5 to 4.0 mEq/L, which was shown by formation of zinc corrosion products within zinc grains. The surface activity was confirmed by applying a titanium hexafluoride pretreatment on the cleaned panels and measuring the lateral microscale uniformity of the formed layer. The uniformity increased when larger areas of galvanized steel became activated by alkaline cleaning. Reactivity of zinc is rather difficult to quantify when setting up an industrial cleaning sequence for galvanized steel. Controlled exposure of cleaned samples in humid supercritical carbon dioxide, followed by quantification of oxidized zinc, provides a straightforward method to evaluate zinc reactivity.
