Abstract:
A liquid polymeric coating composition that upon application to a substrate, such as a coil substrate, preferably does not exhibit the edge build and edge blistering that commonly occurs with conventional liquid polymeric coating compositions. In some embodiments, the liquid polymeric coating composition is modified by tailoring the surface tension, the openness of the coating composition as indicated by the modulus of elasticity, or a combination thereof to reduce edge build and edge blistering. The modified liquid polymeric composition may be applied to a surface of the substrate and cured to form a film coating that reduces or alleviates commonly encountered edge defects in conventional liquid polymeric coating compositions, such as edge build and edge blistering, which may avoid the need for edge trimming of the coated substrate. The coated coil substrate is well suited for forming food or beverage containers or portions thereof.
