It has many merits, such as little environmental pollution, no fire hazard, excellent corrosion resistance, high throwing power and a degree of automation for coatings. Thus, it is widely used in automotives, light industry, agricultural machinery, household appliances, instruments, crafts, building materials and so on. CED coating if often composed of water-soluble cationic resin, pigments and extenders, solvent and neutraliser, which is made by grinding. The cationic resin is the binder of the CED coating and is also the colour developing agent, which is vital to the properties of coating and its film. Thus, the cationic resin is one of the most important components for CED coating. Presently, the main research focuses on increasing kinds of cationic resin and improving the properties of cationic resin. In this paper, the advances of the cationic resin is reviewed.

Determination of cyclic volatile methylsiloxanes in personal care products by gas chromatography / Herbert M. Brothers in INTERNATIONAL JOURNAL OF COSMETIC SCIENCE, Vol. 39, N° 6 (12/2017)  

[article]  inINTERNATIONAL JOURNAL OF COSMETIC SCIENCE > Vol. 39, N° 6 (12/2017) . - p. 580-588 Titre : Determination of cyclic volatile methylsiloxanes in personal care products by gas chromatography Type de document : texte imprimé Auteurs : Herbert M.

Langues : Anglais (eng) Catégories : Chromatographie en phase gazeuse Cosmétiques Cosmétiques -- Analyse Organosilicones shampooings Silicones -- Emploi en cosmétologie Index. décimale : 668.5 Parfums et cosmétiques Résumé : Objective : Organosiloxanes are prevalent in personal care products (PCPs) due to the desired properties they impart in the usage and application of such products. However, the European Chemical Agency (ECHA) has recently published restriction proposals on the amount of two cyclic siloxanes, octamethylcyclotetrasiloxane (D4) and decamethylcyclotetrasiloxane (D5), allowed in wash off products such as shampoos and conditioners which are discharged down the drain during consumer use. This legislation will require that reliable analytical methods are available for manufacturers and government agencies to use in documenting compliance with the restrictions. This article proposes a simple analytical method to enable accurate measurement of these compounds down to the circa 0.1 weight per cent level in PCPs. Methods : Although gas chromatography methods are reported in the literature for quantitation of D4 and D5 in several matrices including PCPs, the potential for generation of false positives due to contamination, co-elution and in situ generation of cyclic volatile methylsiloxanes (cVMS) is always present and needs to be controlled. This report demonstrates the applicability of using a combination of emulsion break, liquid–liquid extraction and silylation sample preparation followed by GC-FID analysis as a suitable means of analysing PCPs for specific cVMS. Results : The reliability and limitations of such methodology were demonstrated through several round-robin studies conducted in the laboratories of a consortium of silicone manufacturers. In addition, this report presents examples of false positives encountered during development of the method and presents a comparative analysis between this method and a published QuEChERS sample preparation procedure to illustrate the potential for generation of false positives when an inappropriate approach is applied to determination of cVMS in personal care products. Conclusion : This report demonstrates that an approach to determine cVMS levels in personal care products is to perform an emulsion break on the sample, isolate the non-polar phase from the emulsion break and treat with a silylation reagent to abate potential in situ formation of cyclics during the course of GC-FID analysis. Round-robin studies conducted in laboratories representing multiple siloxane manufacturers demonstrated the reliability of the GC-FID method when measuring cVMS in PCPs down to circa 0.1%.

One approach receiving increasing interest in recent years has been the use of direct-to-metal (DTM) coatings can be used as replacements for two-layer primer and topcoat systems. Resin suppliers and coatings formulators are taking on the challenge of developing higher-performing, more environmentally friendly technologies for DTM applications in the industrial sector. It gives high gloss, high solid formula. It can be used in indoor and outdoor application. DTM has resistance to moderate environment including intermittent exposure to water, salt, moisture and temperature. DTM can be applied directly to new or rusted metal. It forms tough and long lasting barrier. DTM gives excellent adhesion and prevents the rust.

Fabrication of thermally stable porous films from a cured epoxy resin via the breath figures process / Mikhail A. Soldatov in JOURNAL OF COATINGS TECHNOLOGY AND RESEARCH, Vol. 15, N° 1 (01/2018)

Langues : Américain (ame) Catégories : Copolymères Epoxydes Fluoropolymères Hydrophobie Matériaux poreux Organosilicones Index. décimale : 667.9 Revêtements et enduits Résumé : In the current work, porous films based on epoxy resin have been obtained via the Breath Figures method. It was shown that the use of a low-temperature curing agent and fluoro-containing organosilicon copolymer, compatible with epoxy resin, makes it possible to obtain porous, thermostable, highly hydrophobic coatings with a pore diameter of 3–4 µm. When the epoxy resin/copolymer mixture is homogenous, the modifier prevents water droplet coalescence; otherwise, the mixture becomes heterogeneous, and the positive influence of the modifier is lost. The obtained modified porous films are highly hydrophobic and maintain their porous structure until polymer devitrification occurs. The simplicity of the Breath Figures method shows great potential for the manufacture of water-repellent paint coatings based on epoxy resin for use in a variety of applications.
