Abstract: An article (100) has a polyester film backing (110) and a primer layer (120) including a carboxylated styrene butadiene copolymer crosslinked with a polyfunctional aziridine disposed on a major surface of the polyester film backing (110). Another article includes a polyester backing (110), a primer layer (120) including a carboxylated styrene butadiene copolymer crosslinked with a polyfunctional aziridine disposed on a major surface of the polyester backing (110), and a phenolic layer (140) disposed on the primer layer (120) on a surface opposite the polyester backing (110). The phenolic layer (120) can include abrasive particles (160). Processes for making the articles are also described, as well as methods for abrading a workpiece and improving adhesion between a polyester film backing (110) and a phenolic layer (120) on the polyester backing (110).

Abstract: Methods and apparatuses for roll coating are provided. The roll coating system (100) includes a coating roll (110) having a deformable inner layer (12) with a surface thereof covered by a deformable outer layer (14), the inner layer being softer than the outer layer. A substrate (3) is conveyed to the nip (12) between the coating roll and a back-up roll (120). A metered coating material is transferred from the coating roll to a patterned surface structure (40) of the substrate at the nip to form a conformal coating on the patterned structure of the substrate.
