Claims33
A zinc-rich coated steel article encapsulated by a rubber compound, wherein said rubber compound comprises
- (a) 100 parts by weight of a rubber selected from the group consisting of natural rubber, synthetic rubber and mixtures thereof;
- (b) from 45 to 70 phr of carbon black;
- (c) from 0.5 to 3 phr of a sulfur donor selected from the group consisting of elemental sulfur, polymeric polysulfide, sulfur olefin adducts and mixtures thereof,
- (d) from 1.25 to 3.75 phr of at least one accelerator;
- wherein the weight ratio of sulfur donor to total accelerator present in the wirecoat ranges from 0.4:1 to 0.8:1;
- and
- (e) from 0.2 to 5 phr of cobalt neodecanoate.
