  • Laminates comprising weatherable coatings and primer compositions comprising a mixture of an acrylic polymer and a cellulosic ester
    Patent number: 4181766
    Abstract: The ability to withstand weathering by acrylic substrates having an abrasion resistant coating comprising a cured epoxy-terminated silane on the surface thereof is improved by using a particular primer composition between the coating and the substrate. The primer comprises a mixture of an acrylic polymer and cellulose esters of carboxylic acids.
    Type: Grant
