Paint removers for coatings on plastic substrates and electrodeposited coatings / Rahul Rane in PAINTINDIA, N° spécial (01/2003)
[article]
Titre : Paint removers for coatings on plastic substrates and electrodeposited coatings Type de document : texte imprimé Auteurs : Rahul Rane, Auteur ; Kaustubh Joglekar, Auteur ; V. C. Malshe, Auteur Année de publication : 2003 Article en page(s) : p. 61-84 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : There are three reasons for coating the plastic materials :
a) For functional properties such as to increase the conductivity, to increase the surface properties such as mar resistance, solvent resistance, moisture, air or vapor transmission resistance or even to protect the plastic substrate from light.
b) For decorative purposes
c) Economic purpose. For example instead of using effect pigments in the plastic substrate, it is possible to produce an irridescence by using a coating based on effect pigment in place of blending the pigment in the bulk plastic. Thus the high cost pigment need not be wasted in the bulk of the plastic.
All coated products in the industry require some reworking. A small portion of the production may be totally defective and would require total stripping. In this paper, experimental results of paint removing compositions for electrodeposited metal coatings and plastic coatings are described.Note de contenu : - Removal plastic coatings

Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : Photochromism is the reversible change in the absorption spectrum of a molecule on irradiation by light of certain wavelength. This phenomenon is observed in various compounds. Two types of photochromic polymer systems exist, those in which photo chrome is incorporated into a polymer binder in the form of a solid solution and the others inherently photochromic polymers. This article attempts to review the properties needed forany class of photo-chromic compounds and the mechanisms responsible for the photo chromic effect and also gives an account of the synthesis, structural and physical properties of fulgides, benzopyrans, naphthopyrans, spironaphthoxazines, spirobenzopyrans and their derivatives. The chiral photochromic Liquid Crystalline (LC) polymers are of great importance because they combine the properties of LC polymers and photochromic polymers. The article also covers the extensive applications of the photo chromic polymer systems in the field of ophthalmics, printing, textiles and in optical data storage.

Radicaux libres (chimie)Index. décimale : 667.9 Revêtements et enduits Résumé : The ageing of plastics, polymers and resins leads to several possibilities. Several oxidation products are formed. Free radicals, produced by formation of peroxides, lead to depolymerization, crosslinking, chain termination to polymer leading to chain branching and reversal to monomers in specific cases. Completely new small molecules those were not present at the time of polymerization are formed contributing to volatile organics over the useful life of the product and beyond it. When wa have a look at the literature on the subject of photodegradation of polymers, the polymer chemist dealing with bulk polymers seem to have worried about it far more than the paint and coatings chemist. The reasons are mainly environmental. The used plastic products are posing a great threat to the environment and efforts have been made to delibarately accelerate the process of photodegradation of polymers in ordinary sunlight. A paint and coating chemist can learn a lot from these developments, particularly "what not to do" to enhance the life of his products. Transition metals are regularly used to achieve various objectives by paint and coating chemist. There is a completely new dimension of their involvement in the degradation of polymers by photodegradation mechanism. This review is aimed at the spreading the information to the paints and coatings technologists. There is an increasing concern by government, NGOs and EU institutions about huge problems posed by letter and waste. Plastic products are significant contributors to these problems. The various additives, structural changes produced by oxidation assisted by light have been reviewed. Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=9391
