Vestanat IPDI / Dirk Reichel in PAINTINDIA, ANNUAL 1999 (04/1998)

[article]  inPAINTINDIA > ANNUAL 1999 (04/1998) . - p. 41-48 Titre : Vestanat IPDI Type de document : texte imprimé Auteurs : Dirk Reichel, Auteur Année de publication : 1998 Article en page(s) : p. 41-48 Langues : Anglais (eng) Tags : 'Diisocyanate  organique'  'Cyclohexane  dérivé'  'Réactivité  chimique'  Polyaddition  Polyol  'Réaction  catalytique'  'Urée  Polyuréthane  Prépolymère  'Alkyde  résine'  'Polymère  réticulé'  'Matériau  revêtement'  'Propriété  physicochimique'  'Isophorone  diisocyanate' Index. décimale : 667.9 Revêtements et enduits Résumé : The different reactivity of the aliphatic and cycloaliphatic isocyanate group of Vestanat IPDI (isophorone diisocyanate) using various catalysts is presented. DBTL proved to be the most suitable catalyst for prepolymer synthesis - which is ideally performed at 40-60°C- under consideration of viscosity, monomer content and economical reasons. IPDI prepolymers based on various polymeric polyols were synthesized and their viscosity and content of monomeric IPDI was determined. Using these advantages Vestanat IPDI is the ideal isocyanate for the creation of light stable coatings based on PU-dispersions. By means of experimental data the formation and properties of PU-dispersions and coatings obtained from them is discussed. Vestanat T 1890 is the isocyanurate-trimer of IPDI and widely used as hardener in 2-pack polyurethane systems. The properties and application of Vestanat T 1890 in this field is described with special focus on alkyd resins and blending of HDI-trimer with IPDI-trimer. Non-drying short- and medium oil alkyds as well as air-drying medium-and long oil alkyds can be combined with Vestanat T 1890. By means of a short oil coco alkyd the advantages of this technique are presented. A coating with superior performance is obtained which shows comparable properties to 2-pack acrylic-PU systems. Air-drying alkyds, when combined with Vestanat T 1890 as reactive diluent, show a significant shorter dust-free time and superior weathering durability. Blending of HDI-trimer with Vestanat T 1890 has many advantages which is also presented by means of experimental data. Without change of pot-life not only a shorter dust-free time can be achieved but also the acid etch resistance is improved significantly.

Influence of polyester resins on the matting of powder coatings / Uwe Kubillus in PAINTINDIA, ANNUAL 1999 (04/1998)

[article]  inPAINTINDIA > ANNUAL 1999 (04/1998) . - p: 55-60 Titre : Influence of polyester resins on the matting of powder coatings Type de document : texte imprimé Auteurs : Uwe Kubillus, Auteur ; D. Fink, Auteur Année de publication : 1998 Article en page(s) : p: 55-60 Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : For many applications a matt coating is rather preferred than a high gloss appearance. It can be distinguished between dull matt, matt, semigloss and high gloss coatings. For powder paints different methods and matting agents are available for hybrid, TGIC and TGIC-free systems. Matting effect depends on matting agent, polyester resin and filler types. Corresponding results are presented and influences on film performance are discussed.

New consumers and job coaters are coming up in the market. Powders have registered a production figure of>6000 tons. Types of powder available in India are basically of following three types: * Epoxy pure * Polyester pure * Hybrid pure All over the world, new types of powders are becoming available. The range is very large, e.g. those based on polyurethane, acrylics, teflon, silicon and zinc rich powders for special applications. The range of finishes and colors available also is extensive. However, in India, the demand for specialty powders is quite limited still.
