Coated abrasive articles have a tie layer that is preparable by at least partially polymerizing an isotropic polymerizable composition comprising a polyfunctional aziridine, an acidic free-radically polymerizable monomer, and an oligomer having at least two pendant free-radically polymerizable groups, wherein homopolymerization of the oligomer results in a polymer having a glass transition temperature of less than 50 degrees Celsius.
Les articles abrasifs revêtus ont une couche d'accrochage qui peut être préparée en polymérisant au moins partiellement une composition polymérisable isotropique comprenant une aziridine polyfonctionnelle, un monomère polymérisable à radical libre acide, et un oligomère ayant au moins deux groupes polymérisables à radicaux libre pendants, dans laquelle l'homopolymérisation de l'oligomère aboutit à un polymère ayant une température de transition vitreuse de moins de 50 degrés Celsius.
