Titre : Clear exterior finishes : finding the balance between aesthetics and durability Type de document : texte imprimé Auteurs : Tom Daniel, Auteur ; Marc S. Hirsch, Auteur ; Ken McClelland, Auteur ; Alan S. Ross, Auteur ; R. Sam Williams, Auteur Année de publication : 2004 Article en page(s) : p. 43-48 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 667.9 Revêtements et enduits Résumé : Consumers can easily be confused by the abundance of choices to make when selecting a clear wood finish. There are many types of clear finishes with different characteristics and product claims. This article is designed to help consumers sort out the different finishes and effectively choose which product would be best for their purpose. First, we cover the causes and mechanisms of wood degradation. It is important to know what we are protecting wood from and why. Then we describe in detail the different kinds of clear wood finishes and how they are designed to work. We also cover the attributes of wood as a building material, which explains why people are so interested in using it in the first place.

Titre : Duration of wood preweathering : effect on the service life of subsequently applied paint Type de document : texte imprimé Auteurs : R. Sam Williams, Auteur ; William C. Feist, Auteur Année de publication : 2001 Article en page(s) : p. 65-72 Note générale : Bibliogr. Langues : Américain (ame) Tags : Matériau revêtement Peinture Adhérence Thermoplastique Oléfine polymère Industrie automobile Matière plastique Méthode mesure Adjuvant Index. décimale : 667.9 Revêtements et enduits Résumé : The use of thermoplastic poly(olefins) in the automotive industry continues to proliferate due to their decreased cost and weight and increased recyclability in comparison to thermoplastics such as poly(carbonate) alloys or poly(urethanes). An attribute that continues to hamper the widespread introduction of thermoplastic poly(olefins), in particular thermoplastic olefin (TPO, a blend of impact copolymer and elastomer), into additional automotive components, however, is its poor surface wettability and adhesion. Adhesion promoter formulation, both in terms of resin composition and solvent variation, has been known to influence the adhesive propensity of topcoats when analyzed by typical tests such as peel strength. It has long been disputed, however, that peel strength is not a true measure of paint adhesion since it artificially introduces a film between the paint and the adhesion promoter to enable one to perform the test. In contrast, this paper discusses the use of a newly developed in-situ adhesion test, described as compressive shear delamination (CSD), to quantify the adhesive/cohesive propensity of coatings to a variety of TPO substrates. The effect of solvent type and chlorinated poly(olefin) (CPO) adhesion promoting resin on the adhesion/cohesion of topcoats to TPO is described. Chlorinated poly(olefin) type, followed by solvent variation, was shown to have the most significant impact on the adhesion/cohesion of topcoats. This newly described CSD protocol for determining the weak link in painted plastic may have a significant impact on the choice of topcoat, adhesion promoting primer formulation, and substrate in particular automotive applications.

VernisIndex. décimale : 667.9 Revêtements et enduits Résumé : To quantify the effect of preweathering of new wood surfaces on subsequent finish performance, unfinished wood siding was exposed outdoors for four or eight weeks. Following this preweathering, the specimens were finished with a variety of finishes and placed outdoors again for several years (weathered). The finished specimens were evaluated annually to determine the effect of preweathering on finish performance. The durabilities of 30 different finish systems, consisting of six finishes and five substrates, were evaluated over a five-year period. The wood species were primarily hardwoods and dense softwoods. For these dense species, which weather slowly, a few weeks of preweathering decreased paint performance. The effect of preweathering varied depending on the lenght of time the siding was preweathered, wood species, surface roughness, and finish. The results of the weathering were compared with the results of adhesion testing of similar panels preweathered before finishing.

Huile de linL'huile de lin ou "huile de graines de lin" est une huile de couleur jaune d'or, tirée des graines mûres du lin cultivé, pressées à froid et/ou à chaud ; parfois elle est extraite par un solvant, en vue de l'usage industriel ou artistique, principalement comme siccatif, ou huile auto-siccative.
Les utilisations de l'huile de lin dérivent de sa richesse en acides gras polyinsaturés, en particulier en acides linolénique et linoléique, qui lui doivent leur nom.
L'huile de lin polymérise spontanément à l'air, avec une réaction exothermique : un chiffon imbibé d'huile peut ainsi, dans certaines conditions, s'enflammer spontanément.
Pour ses propriétés de polymère, l'huile de lin est employée seule, ou mélangée à d'autres huiles, résines et solvants, et est utilisée en tant que : Imprégnateur et protecteur des bois à l'intérieur comme à l'extérieur : protection contre l'humidité, les champignons et insectes, et contre la poussière par son caractère antistatique, composant de certains vernis de finition, liant de broyage pour la peinture à l'huile, agent plastifiant du mastic de vitrier, agent durcisseur de diverses préparations, agent de cohérence et liant dans la fabrication du linoléum.

ThuyaIndex. décimale : 667.9 Revêtements et enduits Résumé : Alkyd-, oil-modified-latex-, and latex-based finishes were applied to severely weathered western redcedar and redwood boards that did not have any surface treatment to ameliorate the weathered surface prior to painting. Six finishes were evaluated annually for 11 years for cracking, flaking, erosion, mildew growth, discoloration, and general appearance. Lowsolids-content latex finishes that contained about 10% raw linseed oil and 11% acrylic resin (i.e., the oil-modified latex finishes) performed better on badly weathered wood than did the alkyd and the other latex finish, even after 11 years. Latex finishes that contained raw linseed oil probably stabilized the weathered surface and plasticized the finish. The stabilization of the wood surface and the flexibility of the finish throughout its service life are the important factors in finish performance on these weathered substrates.

Revêtements -- Effets du climatIndex. décimale : 667.9 Revêtements et enduits Résumé : Previous research results involving sulfur accumulation on cross sections of wood coated with latex paint led us to investigate whether acidic conditions could affect the bonding strength of paint and be a factor in catastrophic paint peeling. Through simulation of acidic dew under outdoor conditions, the study reported herein determined the effect of acid rain and/or dew on painted wood siding. Painted wood was soaked before dawn in various acid solutions for two hours each day, then exposed outdoors for the remainder of the day and night during the summer near Madison, WI. From October to May, the specimens were exposed but not soaked. After four years of exposure to weather and acid, only the painted wood interface for specimens soaked in sulfurous acid at pH 2 indicated deterioration as measured by fracture toughness testing.
