Session 5: Architectural Coatings I
The development of an effective water borne technology for exterior paints has become a real 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 paper describes a new product based on OMNOVA’s Low Exudation Binder (LEB) platform, for formulation of exterior paints, where pure acrylic binders are typically used for reasons of excellent colour 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 to extend the application window. Furthermore, paints formulated with the new binder have very low VOC emissions, and are in-line with all the most stringent current environmental requirements.
