## Abstract

Provided among other things is a fabric comprising: a HPPE base fabric; coated thereon a primer polymer; and coated on the primer polymer a liquid-resistant polymer layer. The primer polymer can be a polyurethane. The base fabric can comprise an adhesion promoter that can be a plasticizer. The adhesion promoter can be a sulfonic acid plasticizer. The adhesion promoter can contain an active hydrogen, carboxy, carboxyloxy or acid group. The fabric can comprise, coated on the liquid-resistant polymer layer, an additional polymer layer. The additional polymer layer can comprise carnauba wax in an amount from about 1 to 3% Phr. The liquid-resistant polymer layer can be a NBR layer. In certain embodiments, the fabric shows no delamination of the liquid-resistant polymer layer after an adherence test. The primer layer can be a polyurethane layer. These features can be present in any combination.
