Tension superficielleIndex. décimale : 667.9 Revêtements et enduits Résumé : To prevent air entrapment and foaming, defoamers are usually added to water-borne coating formulations. Defoamer performance was studied by capturing high resolution images of a coating sprayed on glass substrates. Image analysis provided a quantitative measure of the efficacy of additives. Surprisingly, the most effective product was a non-ionic wetting agent rather than a defoamer. Note de contenu : - Surface tension measurement procedure

Bois extérieursTags : 'Taches semi-transparentes' 'Traitement pression bois' 'Détérioration naturelle' 'Partial least square-regression (PLS-R) modeling' Index. décimale : 667.9 Revêtements et enduits Résumé : Understanding how a coating’s properties are related to its performance characteristics and how measuring its properties can be used for predicting the performance of coating in service was the main focus of this study. A number of exterior penetrating wood stains were characterized in terms of glass transition temperature (T g), solid content, viscosity, and surface tension. The contact angles of liquid coatings were measured on wood treated with chromated copper arsenate, alkaline copper quat, and copper azole as well as untreated wood. Also, the film thicknesses of the cured coatings on wood surfaces were measured by back-scattered electron imaging of osmium-treated samples. Partial least square-regression (PLS-R) modeling was used to correlate measured coating properties with their weathering performance on the preservative-treated and untreated wood substrates, based on water repellency, color retention, and visual ratings after 3 years of natural weathering. A PLS model was developed with 77% fitting accuracy and 69% prediction ability. This model indicated that preservative treatments significantly affected coating performance, and among coating properties, film thickness, viscosity, and glass transition temperature had the greatest effects on the coatings’ performance in exterior.
