Titre : Novelty finishes based on acid functional acrylic copolymers Type de document : texte imprimé Auteurs : D. A. Raval, Auteur ; A. K. Dighe, Auteur ; R. J. Parmar, Auteur Année de publication : 2001 Article en page(s) : p. 35-40 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : Novelty finishes like hammertone, stipple and multicolour were prepared from acid functional acrylic copolymers. These finishes were based on these copolymer resins of thermoplastic and thermosetting types. Both the types of copolymers were neutralised with triethylamine and made water compatible with the help of cosolvent butylcellosolve. Pigments and additives were added accordingly in the preparation of these novelty finishes. Special application techniques were used to apply these coatings (finishes). Thus an attempt was made for the preparation of ecofriendly novelty finishes. Note de contenu : - Materials and methods

Titre : Effect of functionality and molecular weight of polyester on elastomeric properties of 2K polyurethane coatings Type de document : texte imprimé Auteurs : H. S. Joglekar, Auteur ; K. V. Dave, Auteur Année de publication : 2001 Article en page(s) : p. 41-46 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : The concept of 2K polyurethane coatings having good elastomeric properties is getting widely appreciated all across. The conventional polyesters fail in rendering elastomeric properties. In order to synthesise the right type of polyester suitable for 2K polyurethane coatings imparting good elastomeric properties, a comprehensive study has been done. This paper will focus on an important aspect of effect of functionality and molecular weight of polyesters on elastomeric properties of 2K polyurethane coatings. The study highlights the structural requirements of a polymer backbone having high cohesive energy and offering the desired performance. Such systems are described in detail w.r. t. specific performance requirements, formulations, processing techniques, application method and evaluation findings. Different polyester-polyol systems designed show good elastomeric properties based on a definite optimal balance molecular flexibility and chain stiffness so as to offer better elastomeric properties.

Titre : What is a thermic fluid heating system ? Type de document : texte imprimé Auteurs : Charuchandra Dewasthale, Auteur Année de publication : 2001 Article en page(s) : p. 47-52 Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : A thermic fluid system is used for heating required in the process by means of circulating a media, which is capable of absorbing and releasing the heat as and when required. The main components of a thermic fluid (henceforth called TF) systems are : (1) heater and its accessories; (2) media (thermic fluid); (3) piping and user equipment.
The major advantages of this system are :
1. A thermic is not governed by IBR, but it comes under the factory inspectorate.
2. Since there is no water involved, expensive water treatment cost is eliminated. So is the cause for choking and puncturing or downtime.
3. Energy efficient operations. Overall system efficiency of TF system is always higher than a conventional heating system (say steam).
4. Skilled manpower to handle and operate a system is not required. (like in the case of boilers, we require an IBR approved attendant).
5. Higher temperatures can be attained at atmospheric pressures.
