Langues : Anglais (eng) Catégories : Diluants Hydrophobie Polyols Polyuréthanes Résistance à l'hydrolyse Index. décimale : 667.9 Revêtements et enduits Résumé : The authors explain why the use of hydrophobic polyols can achieve better surface performance in coating and flooring applications. Oleochemical polyols are spacial polyfunctional alcohols based on natural vegetable oils. They offer alternatives to higher hydrophilicity petrochemical-based polyols. Because they are derivatives of vegetable triglyceride oils, they retain the advantages of classical oil paints and alkyd resins. But because of their low viscosity, they offer a base for solvent-free, full solids coating systems. As so-called reactive diluents, they are additionally able to replace solvents in coatings by forming part of the polymer film after curing instead of evaporating as solvent do.

Chameleon coatings / Klaus Dartmann in POLYMERS PAINT COLOUR JOURNAL - PPCJ, Vol. 192, N° 4453 (06/2002)

[article]  inPOLYMERS PAINT COLOUR JOURNAL - PPCJ > Vol. 192, N° 4453 (06/2002) . - p. 23 Titre : Chameleon coatings Type de document : texte imprimé Auteurs : Klaus Dartmann, Auteur Année de publication : 2002 Article en page(s) : p. 23 Langues : Anglais (eng) Catégories : Bois Décoration et ornement Mélange Polyuréthanes Revêtements décoratifs Index. décimale : 667.9 Revêtements et enduits Résumé : The author explains how a woodstain mixing system and a little skill can together create individual design finishes for indoor wooden surfaces. Special effect coatings such as marbled, speckled or water droplet patterns give an individual design to indoor wooden surfaces. With the introduction of 15 special effect coatings, the range of Glasurit products for furniture, doors and interior woodwork is now complete. The basis for simple handling is a woodstain mixing system in which an additive is added to a PU base coat. The PU coating technology provides special effect coatings with a high level of resistance stress. Suitable substrates are chiefly MDF, chipboards and melamine resin or urea resin-coated base foils. Surfaces should be sanded carefully before coating and after applying a polyurethane universal primer. To obtain an optimal assessment of the surface effect on the respective substrate and in the ambient situation, it is recommended that a trial coating be applied. However, one must not forget that the exclusiveness of these coatings depends on the imagination, skill and technique of the user.

Mixing and matching / Simo Laitala in POLYMERS PAINT COLOUR JOURNAL - PPCJ, Vol. 192, N° 4453 (06/2002)

[article]  inPOLYMERS PAINT COLOUR JOURNAL - PPCJ > Vol. 192, N° 4453 (06/2002) . - p. 28-30 Titre : Mixing and matching Type de document : texte imprimé Auteurs : Simo Laitala, Auteur Année de publication : 2002 Article en page(s) : p. 28-30 Langues : Anglais (eng) Catégories : Matériaux -- Coloration Mélanges (chimie) Teinture Teinture -- Appareils et matériels Index. décimale : 667.9 Revêtements et enduits Résumé : In-house tinting and mixing, so much a feature of DIY retail outlets, also has a place in the factory as the author explains. Tinting systems in Europe and the United States have long gained a place in many paint manufacturers' minds. Especially at Point-of-Sale, tinting systems have become a standard. Their current lower penetration in other parts of the world is rapidly catching up. Tinting systems created a clear win-win situation for Point-of-Sale, by serving both the consumers' wishes for instant 'colour on demand' and the shop owner's need for lower stock and increased profitability. In-plat tinting systems however, are still not very commonly used. Maybe it is time for paint munufacturers - decorative and industrial - to reconsider their way of thinking about in-plant tinting? Manufacturer's face a dilemma between efficiently producing colour and serving customer demands adequately. There are areas of tension between conventional colour making and today's technical possibilities. An integrated business solution for this dilemma includes special in-plant colourants, software to support the production method selection process. Additionally, new advanced production methods are introduced. Manufacturers can now tailor each individual order in their colouring process, keeping in mind customer's wishes and their own profitability.
