Product Description

Metalastic was allegedly marketed by Sherwin-Williams as a heavy-duty protective coating for marine and industrial steel — hull exteriors, ballast and cargo tanks, bilge areas, superstructure steel, storage tanks, and structural members exposed to salt spray and industrial corrosion. Plaintiffs have alleged in publicly filed U.S. asbestos personal-injury and wrongful-death litigation that certain grades of Metalastic and companion Sherwin-Williams marine coatings allegedly incorporated chrysotile asbestos fiber as a reinforcing and anti-sag additive that helped the film build thickness without slumping on vertical steel.

According to publicly filed asbestos litigation records, the asbestos-fibered formulation was allegedly sold in cans and drums to Navy shipyards, private shipbuilders and repair yards, tank-farm contractors, and refinery maintenance departments through the mid-20th century.

Workers Exposed

Plaintiffs allegedly identified in litigation the trades most consistently exposed to Metalastic dust:

  • Shipyard painters spray-applying and brush-applying the coating in confined tanks and holds
  • Sandblasters and grit-blasters removing weathered Metalastic during recoat cycles
  • Boilermakers and steelworkers cutting or welding through painted steel, releasing burn-off fumes and residue
  • Insulators and pipefitters working adjacent to freshly sanded painted surfaces
  • Tank cleaners and refinery maintenance crews scraping legacy Metalastic film during vessel entries
