ThredOn® Weather Coat
Protective Coating for Machinery and Tubulars
ThredOn® Weather Coat is a protective coating used in machine shops, pipe yards, offshore platforms or anywhere metal needs to be protected for short or long periods of time. It leaves a semi-fluid, non-hardening coating that protects metal against rust and corrosion for extended periods in sun, rain, sand, salt-water and/or frigid temperatures. Weather Coat can be brushed on or thinned with mineral spirits and sprayed on or used for dip coating. It can be removed using common solvents such as diesel or paint thinner.
