Stabilité hydrolytiqueIndex. décimale : 667.9 Revêtements et enduits Résumé : Green Chemistry enables us to think beyond the con ventional materials synthesized for different applications. One such approach is the development of polyurethanes via an isocyanate free route. The chemistry is broadly based on the reaction of cyclocarbonate groups and primary diamines. The cyclocarbonate groups are synthesized bycarbonation of epoxy moieties. This opens a door for new possibilities of structure property variation in the Non Isocyanate PolyUrethanes (NIPU) and also leads to synthesis of hybrid acrylic PU and hybrid epoxy NIPU. The two monomers mainly discussed in this paper are Glycidyl acrylate and Glycidyl methacrylate which are synthesised by the reaction of epichlorohydrin with acrylic acid and methacrylic acid respectively. These monomers are then polymerized via free radical polymerization to produce glycidyl acrylate simultaneously reaction with carbon dioxide to synthesize a polymer having both epoxy groups and cyclocarbonate groups in the side chains. NIPU can also be synthesized from renewable resources also. NIPU has wide applications and can be replacement of conventional PUs in future.

Emulsions
Revêtements (produits chimiques)Index. décimale : 665.1 Cires Résumé : A wax emulsion is a stable mixture of one or more waxes in water. Waxes and water are normally immiscible but can be brought together stably by the use of surfactants and a clever preparation process. Strictly speaking a wax emulsion should be called a wax dispersion since the wax is solid at room temperature. However, because the preparation takes place above the melting point of the wax, the actual process is called emulsification, hence the name wax emulsion.
Wax Emulsions or Wax dispersions are widely used for optimizing the final performance of coating & inks by efficiently controlling surface properties, even if used in relatively small quantifies < 5%, - waxes enhance properties such as water repellency, slip, abrasion resistance anti-blocking and other critical properties in paints, coating, leather, wood coatings, foundries and ink areas.Note de contenu : - ORIGIN OF WAXES : Paraffin wax - PE wax - Characteristics & features (paraffin & PE wax) - OPE wax -oxidized polyethylene wax

Revêtements en phase aqueuse:Peinture en phase aqueuseIndex. décimale : 667.6 Peintures Résumé : Now let us go in detail the various reasons why Paints go bad in stored conditions or in-can. The main reason that is attributed is due to the contamination of paint with micro organisms. This can also be called as Bio-degradation of paints. Herein we wiII examine this aspect and then suggest methods to avoid paint going bad.
The protection of paint from attack by microorganisms is an area of the coatings formulation that is often misunderstood. This chapter provides an understanding of microbial contamination and can assist coatings manufacturers in preparing to do battle with the problems created by microbiological organisms. The types of microbial attack that are of concern to the paint industry are bacterial, fungal and algal. Bacteria, small, single-celled organisms, grow readily in unpreserved water-based systems. Fungi are unicellular or filamentous organisms that are devoid of chlorophyll and attack the dry paint film, as do algae, which are unicellular or filamentous organisms that require light. While only waterborne coatings are susceptible to bacterial contamination in the can, both water- and solvent borne coatings are prone to attack on the dry film by fungi and algae after the paint is applied.En ligne : https://drive.google.com/file/d/1ttaNtX_MGlJIrW1znZWBdbLvFjoHkue6/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=35243 [article]Réservation
