CA 2321699
A laminar structure comprised of at least one layer of glass and a sheet of plasticized PVB containing an adhesion control agent is provided wherein delamination resulting from air being dispersed or entrapped and dissolved in the PVB is controlled by use of a surface energy modifying agent, said surface energy modifying agent being selected to provide a total surface energy for the sheet of less than 52 dynes/cm.
Cette structure feuilletée est constituée d'au moins une couche de verre et d'une feuille de poly(butyral de vinyle) (PVB) plastifié contenant un agent de régulation de l'adhérence. La déstratification provoquée par l'air dispersé ou piégé et dissout dans le PVB est enrayée grâce un agent de modification de la tension superficielle, cet agent ayant été choisi de manière à assurer à la feuille une tension superficielle totale inférieure à 52 dynes par centimètre.
