Revêtements en bâtimentIndex. décimale : 667.9 Revêtements et enduits Résumé : High humidity and precipitation challenges the ability of exterior architectural coatings to properly cure and provide the necessary protection of exterior surfaces. To increase early rain resistance and decrease water sensitivity, different formulation techniques were investigated. Raw materials were evaluated in a standard starting point formula to generate an optimal formulation that reduces water sensitivity and surfactant leaching, while simultaneously increasing early rain resistance. Results for early rain resistance were determined by developing new testing methodology that varied environmental factors during the film curing process. We determined that using functional additives as well as increasing the hydrophobicity of the coating film can substantially increase early rain resistance.

Revêtements en phase aqueuse -- Additifs:Peinture en phase aqueuse -- AdditifsIndex. décimale : 667.9 Revêtements et enduits Résumé : The development of an effective waterborne technology for exterior paints has become a significant challenge in the architectural coatings market due to the growing expectations of end users (total cost of ownership), diversification of materials used for exterior walls and siding, and the continuous trend towards VOC reduction. This article describes a new product based on our company's Low Exudation Binder (LEB) platform, designed for formulation of exterior paints, where pure acrylic binders are typically used for reasons of excellent color retention in very deep tones. The new binder possesses the advantages common to those of the LEB technology, namely very low surfactant leaching, excellent resistance to efflorescence, and long-term adhesion, and in addition, very early rain resistance, allowing the application window to be extended. Furthermore, paints formulated with the new binder have very low VOC emissions, and are in-line with all the most stringent, current environmental requirements.
