Coating evolution with new higher solids resins for 2-K car refinishing and industrial finishes / Ulrich Epple in PAINTINDIA, Vol. LIV, N° 10 (10/2004)

[article]  inPAINTINDIA > Vol. LIV, N° 10 (10/2004) . - p. 35-41 Titre : Coating evolution with new higher solids resins for 2-K car refinishing and industrial finishes Type de document : texte imprimé Auteurs : Ulrich Epple, Auteur ; Ulrike Kuttler, Auteur Année de publication : 2004 Article en page(s) : p. 35-41 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : For VOC compliant we synthesized different low molecular binders: acrylic and polyester polyols with bulky monomers and high functionalities. An overview of the available guiding formulations: clearcoats, pigmented coatings, primer surfacers and primers (anti-corrosive) for high performance protective coatings and the commercial vehicle market are presented in Fig.13. It's also possible to blend high solid acrylic resins with our new ultra high solid polyester polyols for emission reduction. For industrial maintenance, like agricultural and industrial machinery, building machinery or general equipment (e.g. bridges, hydrants), we offer new high solids products with a reduced OH content (fig.14). All products are worth their money.

Paint additives - Part I / S. C. Jain in PAINTINDIA, Vol. LIV, N° 10 (10/2004)

[article]  inPAINTINDIA > Vol. LIV, N° 10 (10/2004) . - p. 43-46 Titre : Paint additives - Part I Type de document : texte imprimé Auteurs : S. C. Jain, Auteur Année de publication : 2004 Article en page(s) : p. 43-46 Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : An organic coating formulation is generally made-up of a polymeric binder or a combination of binders, pigments and extenders, carrier components-volatile liquids (solvents or water) in liquid paints and air in powder coatings and a number of additives. The coating has to pass through a number of diverse stages during its usage cycle production, transportation, storage, application, film formation and the performance as final coating film. A well-balanced composition should exhibit desired properties during all the stages.

A comprehensive review on adhesives Part I: Concept, theories, classification and uses / A. G. Patil in PAINTINDIA, Vol. LIV, N° 10 (10/2004)

[article]  inPAINTINDIA > Vol. LIV, N° 10 (10/2004) . - p. 47-54 Titre : A comprehensive review on adhesives Part I: Concept, theories, classification and uses Type de document : texte imprimé Auteurs : A. G. Patil, Auteur ; S. H. Bidkar, Auteur ; U. R. Kapadi, Auteur ; D. G. Hundiwale, Auteur Année de publication : 2004 Article en page(s) : p. 47-54 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : The adhesive revolution is in a fast development in the modern age. Historical study shows that adhesive joining is one of the older techniques. Adhesives were not seriously considered as structural bonding agents for long time. In the last couple of decades, adhesives in a variety of forms have replaced the use of screws, rivets, welds, nails, pegs, bolts, trads, clamping, soldering and brazing in many fields. "Adhesive is defined as non metallic materials i.e. capable of joining bodies together by surface adhesion and internal strength (adhesion and cohesion) without the structure of bodies undergoing significant changes. "The process of joining the two or more surface is known as adhesion. The substances loosely covered by thi definition of adhesive are cements, glue, paste, gums, sealants bonding agent. The basic function of an adhesive is to fasten the components of an assembly together and maintain the joined parts under the service conditions but the two parts can be bonded by other method also. The adhesives for bonding assumes the process is fast, easy and economical. An ideal adhesives should have maximum mechanical strength of bond, minimum setting time or quick development of bond strength, ease and rapidity of application, resistsance to moisture, ability to withstand temperature, produce a flexible bond, resistance to deterioration by aging, should be chemically inert to the adherands and should have free from objectionable odour, fire and toxicity hazards. An adhesive is composed of basic raw materials which are called binders and which determines its adhesiveness (adhesion) and its internal strength (cohesion) and of frequently necessary auxiliaries which establish particular end use and processing characteristics. The adhesiveness of an adhesive, its processing characteristic are the fundamental properties that determine its suitability for use in forming adhesive joint. The binders used for adhesives are primarily high polymers having optimal strength properties.
