Polyéther de siliconeIndex. décimale : 667.9 Revêtements et enduits Résumé : Food packaging regulations could severely limit material choice for the ink and varnish industry.
The rules and regulations for the use of printing inks and over print varnishes in contact with food severely limit the choice of materials available to printing inks and varnish formulators for food packaging applications. With expertise in modifying the archecture of silicone-polyeter copolymer technology, we are able to design structures to achieve good foam control and film quality in the manufacture and application of waterborne inks and varnishes, whilst most importantly allows compliance to food packaging legislation in place to protect the public.Note de contenu : - Structure of silicone-polyether copolymers

Tension superficielleIndex. décimale : 667.9 Revêtements et enduits Résumé : The use of surfactats to improve the wetting performance of coatings is of great importance, in particular for waterborne coatings. Increasingly, water-based coating systems are formulated for more demanding applications. To comply with emission regulations, organic solvent content is reduced or elimined. An undesired effect of this reformulation is a drop in the wetting properties of the coatings. This has a dramatic effect, in particular, on the performance of coatings applied to low-energy substrates. In this paper we discuss the use of silocone surfactants to lower the surface tension of waterborne coatings and investigate the relationship between silicone surfactant chemical structure and wetting properties.

Revêtements en bâtiment:Peinture en bâtimentIndex. décimale : 667.9 Revêtements et enduits Résumé : Trends in the decorative market are strongly driven by two sources today. The first driver is legislation, where compliance to Volatile Organic Compounds (VOC) regulations is non-negotiable and is forcing formulators to look carefully at all their ingredients (including additives) to control VOC to low levels (<50g/l). The second driver, and arguably the most important, is the end consumer, who are asking for longer lasting,better performing products from the OEM producers and additionally easier to use products thar are "less harmful" to themselves and their families in the Do-It-Yourself market - this could mean lowder odor,less solvent or quicker drying for example - and there is an ever growing popularity of "eco" brands in the market. For home-use architectural paints, the good hiding power, good wetting and low dirt pick-up is important to the end user. The desire to achieve better hiding power of paints results in an open film with high PVC (Pigment Volume Concentration which often has limitations with respect to water resistance, weter beading and dirt pick-up. For wood coatings, water resistance is also an extremely important attribute to prevent peeling and cracking but also to maintain the aesthetics of the coatings. OEM applied wood coatings also require anti-blocking resistance during production, storage and shipping to prevent damage to the goods.
This paper demonstrates how silicone chemistry can help formulator meet both the environmental and performance demands of the end consumer, giving the formulator possibilities to differentiate their product line or indeed achieve the same performance of current commercial paints or coatings more economically. In doing so they are also meeting the necessary legislative regulations. Dow Corning 87 Additive and Dow Corning 88 Additive are new silicone-based additives which bring differentiated performance to the en user - we will demonstrate how, at low levels (typically 2-5%) these additives impart good water resistance, and we will sho examples in architectural paints compared to the incumbent silicone resin emulsion technology (typically used at 5-10%). Dow Corning 87 additives will also impart water beading, a property typically perceived by the end user as meaning excellent water resistance, giving a 2-in-1 additive option and simplifying the formulation. Lastly we will show the possibilities to bring a anti-blocking as a secondary attribute to wood coatings.
Whilst we endeavor to provide the requirements of the end user, of course we also to consider the needs of the formulator during the paint making process ! They too have needs to meet, especially with respect to foam control, which cancause problems during the manufacturing and filling processes. In this paper we will also show how Dow Corning 62 Additive and Dow Corning 68 Additive -highs solids silicone emulsions - can be used at lower addition levels to achieve good foam control. Finally all these attributes must come at an afordable cost. We will demonstrate the effectiveness of the various Dow Corning additives at low addition levels in the paint to reach this final goal.Note de contenu : - Improving the durability of architectural paints
