| description | The present invention provides compositions for and methods of rapidly making roof coatings, wherein two-component aqueous compositions comprise a component one that has a pH of from 7.5 to 10 (i) one or more emulsion copolymers having a glass transition temperature (Tg) as determined by differential scanning calorimetry (DSC) of from -45°C to 0°C, and (ii) one or more anionic surfactants, and, in a separate component, (iii) an aqueous acid chosen from a (poly)carboxylic acid or polymeric polyacid. The compositions have little or no ammonia, set within 10 minutes, preferably, a minute or less, and allow one to apply a film as thick as from 0.3 to 3 mm in a single application by co-spraying the two-components or applying them sequentially in one or several passes over a roofing substrate.
La présente invention concerne des compositions et des procédés destinés à la fabrication rapide d'enduits pour toiture, des compositions aqueuses à deux constituants comprenant un constituant d'un pH compris entre 7,5 et 10 (i) un ou plusieurs copolymères en émulsion d'une température de transition vitreuse (Tg) telle que déterminée par analyse calorimétrique différentielle (ACD) comprise entre -45 °C et 0 °C, et (ii) un ou plusieurs tensioactifs anioniques et, dans un constituant séparé, (iii) un acide aqueux choisi parmi un acide (poly)carboxylique et un polyacide polymère. Les compositions présentent peu ou pas d'ammoniac, durcissent dans les 10 minutes, de préférence, en une minute ou moins, et permettent d'appliquer un film épais de 0,3 à 3 mm en une application unique par co-pulvérisation des deux constituants ou en les appliquant séquentiellement en une ou plusieurs fois sur un substrat de toiture. |
