ABSTRACT:
A duo bonding layer for adhering a chlorinated polyethylene layer or coating to a rubber-lined article. The first bonding layer contains a blend of material having from 75 to 25 percent of chlorinated polyethylene by weight and from 25 to 75 percent by weight of an elastomer of natural rubber, a rubber homopolymer, or a rubber copolymer. The second bonding layer contains a blend of the same material but with the amount of chlorinated polyethylene by weight ranging from 90 to 55 percent and the amount of the elastomer ranging from 10 to 45 percent by weight. The first bonding layer is generally attached to a rubber layer such as natural rubber, which in turn is bonded directly to an article. The second bonding layer is attached to the chlorinated polyethylene layer.
