Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : Wood coatings - Conventional light stabilisers based on iron oxide provide good protection for wood, but change its colour. However, products now exist that do the job without affecting the natural colour of the substrate. The right combination of organic and inorganic variants together with radical scavengers proves to be the solution.

Corrosion protection and photo-activity with nanoparticles / Thomas Rentschler in DOUBLE LIAISON, N° 553 (11/2006)

[article]  inDOUBLE LIAISON > N° 553 (11/2006) . - p. 35-50 Titre : Corrosion protection and photo-activity with nanoparticles Type de document : texte imprimé Auteurs : Thomas Rentschler, Auteur Année de publication : 2006 Article en page(s) : p. 35-50 Note générale : Bibliogr. Langues : Français (fre) Catégories : Anticorrosifs Coil coatings Nanoparticules Photocatalyse Sulfate de baryum Index. décimale : 667.9 Revêtements et enduits Résumé : The chemical performance of nanosized barium sulfate for anticorrosive properties in UV-curing coil coating and the photoactivity of titanium dioxide will be demonstrated. It has been established that nanosized barium sulfate can act as an active additive for the deflocculation of pigments although knowin that these products are more than inert materials it was still surprising to find a significant improvement of anticorrosive properties of UV-curing primers for coil coatings. In epoxy acrylate and urethane acrylate systems the adhesion and corrosion protection qere increased substantially. Photoactive paints are on their way to the market withselfcleaning and deodorizing properties evolving from nanosized titanium dioxide. The discoloration of methylene blue and the photoxidation of isopropanole are introduced as evaluation methods for photoactivity. Results from outdoor exposures of paints point to their activity and the recommended concentration of the photocatalyst.

Determination of hydroxyl groups on the surface of TiO2 pigments / Thomas Rentschler in EUROPEAN COATINGS JOURNAL (ECJ), N° 10/97 (10/1997)

[article]  inEUROPEAN COATINGS JOURNAL (ECJ) > N° 10/97 (10/1997) . - p. 939-941 Titre : Determination of hydroxyl groups on the surface of TiO2 pigments Type de document : texte imprimé Auteurs : Thomas Rentschler, Auteur Année de publication : 1997 Article en page(s) : p. 939-941 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Dioxyde de titane Groupe hydroxyle Pigments inorganiques Surfaces -- Analyse Volumétrie (chimie analytique) Index. décimale : 667.9 Revêtements et enduits Résumé : The hydroxyl group density on the surface of well defined TiO2 pigments was determined by a specifically adopted volumetric method using LiCH3 as a reagent. The anatase samples exhibited a significantly higher amount of OH groups compared to the rutiles, respectively. Possible origins of different photoactivity and chalking behaviour are discussed with respect to these findings.

Effective hiding with thin-film powder coatings and partial replacement of TiO2 / Thomas Rentschler in PAINTINDIA, Vol. LV, N° 8 (08/2005)

[article]  inPAINTINDIA > Vol. LV, N° 8 (08/2005) . - p. 73-78 Titre : Effective hiding with thin-film powder coatings and partial replacement of TiO2 Type de document : texte imprimé Auteurs : Thomas Rentschler, Auteur ; Angela Classen, Auteur ; Horst Van Beek, Auteur ; Peter Gribble, Auteur Année de publication : 2005 Article en page(s) : p. 73-78 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : Powder coating systems with film thicknesses of < 50 pm have been repeatably produced for the white goods segment of the market. No less than 30% of the quantity of titanium dioxide normally used was replaced with materials of differing particle sizes and particle-size distribution widths. High-quality standard materials act as genuine extenders and do not modify the properties of the paint system in any way. Finer-particled products make a positive contribution to hiding power, gloss and mechanical properties. An extra functionality is added to the system in this context, depending on particle size, but does have its practical limitations, with respect to rheological characteristics. Note de contenu : - How thin are thin films? - 30% titanium dioxide replaced - Optical properties - Hiding power of thin films - Mechanical properties unaffected - Extremely good resistance - Discussion - Experimental details Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=11644 [article]

Functional effect pigments in coatings / Thomas Rentschler in POLYMERS PAINT COLOUR JOURNAL - PPCJ, Vol. 202, N° 4571 (04/2012)  

[article]  inPOLYMERS PAINT COLOUR JOURNAL - PPCJ > Vol. 202, N° 4571 (04/2012) . - p. 27-28 Titre : Functional effect pigments in coatings Type de document : texte imprimé Auteurs : Thomas Rentschler, Auteur ; Matthias Kuntz, Auteur Année de publication : 2012 Article en page(s) : p. 27-28 Langues : Anglais (eng) Catégories : Pigments à effets spéciaux Index. décimale : 667.2 Colorants et pigments Résumé : The use of functional pigments can be seen in applications flooring to radiation interaction. Well-known effect pigments are plate-like particles, which are either metallic flakes or pearlescent pigments. Metallic flakes are predominantly made of aluminium, which reflect light to a very high extent, thus leading to brightly shining silver colour effects with a noticeable hiding power. In contrast to the metallic pigments, pearlescent pigments are composite materials, based on platelet substrates, which are typically coated with one or more additional metal oxide layers. Their effect as pearl lustre pigments originates from an interference phenomenon and their colour is determined by the refractive index and thickness of the precipitated metal oxide layer. Typically, these effect pigments are not considered as functional pigments, even though they split the incident, white light into a portion of the reflected, interference colour and the transmitted, complementary colour. However, if the understanding of functionality could be expanded beyond the pure technological purposes towards meeting all expectations, the often-decisive impact of our emotions becomes part of the game. "All men are equal, they are individuals". As such, effect pigments draw our interest to attractively coated objects. Their function is to creat new desires and to fulfil our wishes. Sparkling and colourful, maybe even colour changing pearlescent pigments have successfully kept their promises and become famous for their outstanding properties.
