Emergence of polyurea resins as prolific material for surface coatings / M. V. K. kannan in PAINTINDIA, Vol. LIX, N° 1 (01/2009)
[article]
Titre : Emergence of polyurea resins as prolific material for surface coatings Type de document : texte imprimé Auteurs : M. V. K. kannan, Auteur Année de publication : 2009 Article en page(s) : p. 71-84 Langues : Anglais (eng) Catégories : Polyurée
Revêtement de surfaceIndex. décimale : 667.9 Revêtements et enduits Résumé : When the world is witnessing the best of awareness amongst en users, towards protecting their assets and successfully combating the wrath of nature of various unwanted corrosion and destructive forces trhough various coating materials, the birth of polyurea family of resins is rather timely and is expected to rule the future of the coating industry by far. It is not an exaggeration in saying that the polyurea coatings are relatively new when compared to the conventional coatings in the protective aspects like epoxies, acrylics and polyurethanes. Their emergence into this world is no more than 20 to 25 years and is all but said that lesser known outside the continent of the USA and in a lesser scale at some of the European locations. The earliest reference to polymeric spray elastomeric coatings is traceable to about 2 decades at Texaco Chemical Company in Austin. This company is popularly known today as Huntsman Corporation.

Revêtements en phase aqueuse:Peinture en phase aqueuseIndex. décimale : 667.9 Revêtements et enduits Résumé : The emulsion is a dispersion of two immiscible liquide. In which one liquid is dispersed phase and other is continuous phase. Waterborne coating scores over solventborne coating in various respects like reduced toxicity, odour, flammability and environmental risk. The use of polymeric materials, in powder form, has been growing over the past ten years at a high rate. The success is the result of environmental and economical advantages, combined with energy saving and good application properties. The supply of liquid emulsions is disadvantageous as the transportation is expensive, emulsions may be destabilized or change its quality with lapse of time and treatment of waste water may be required after the use of emulsions. In the view of these disadvantages recently emulsions are dried. Under the right conditions powders can behave as fluids and be disposed and blended quickly and can be used for adhesive, paint, cement mortar paper coating applications.

Adhésifs sensibles à la pressionIndex. décimale : 668.3 Adhésifs et produits semblables Résumé : Pressure sensitive adhesives are materials that form a bond with very light pressure. The cured adhesive is neither solid nor liquid, but rather is a vicoelastic material that is usually quite tacky. Pressure sensitive adhesives are generally categorized into solvent based, water based and radiation cured adhesives. The former covers larger share in the market, but with realization of high VOC (Volatile Organic Content) and effects on environment, major focus is shifted to water based adhesives. The advantages of water-based PSAs are the abatement of air pollution (low VOC) and generally enhanced oxidation resistance of the final film. Radiation cured adhesives are now being employed because of their advantages over other two methods but it too has limitations. It is necessary to utilize the advantages using combination of above methods. This article mainly discusses about the radiation cured water based adhesives - its synthesis and application. Radiation cured water based adhesives do not currently command a significant market share but the interes remains high in this type of pressure sensitive adhesive technology. A number of important relationships between the proportion of these adhesives and both cure and formulating parameters have been uncovered. Use of these relationships can significantly enhance the chances or designing and optimizing superior ultraviolet/electron beam cured water based pressure sensitive adhesives.

Titre : Super absorbent polymers Type de document : texte imprimé Auteurs : Shilpi Sanghi, Auteur ; Atri Rungta, Auteur ; V. C. Malshe, Auteur Année de publication : 2009 Article en page(s) : p. 113-120 Langues : Anglais (eng) Catégories : Absorbants et adsorbants
PolymèresIndex. décimale : 668.9 Polymères Résumé : Superabsorbent polymers (SAPs) are materials that have the ability to absorb and retain large volumes of water and aqueous solutions or solvents. They were first developed by the United States Department of Agriculture in the la 1960s for conditioning the soiil in the arid area. These polymers could absorb several hundred times water of their own weight and thus retain the moisture in the soil. Thus even with a small rain fall, the water does not flow off or percolate in the ground butremains available on or very slightly below the surface. Thereafter, many improvements have taken place in this field. Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=6934
