ABSTRACT:
A method is disclosed of coating articles of manufacture to prevent corrosion which comprises applying a thermoplastic coating material to the article, applying a layer of fibrous material over the coating material, wetting the layer of fibrous material, and heating the three components, whereby contraction of the fibrous material, during heating, will compress the coating material and counteract its deformation tendencies such that it is well bonded to the article. The thermoplastic coating material is preferably applied in the form of a coating tape comprising the thermoplastic coating material and a thermoplastic adhesive and is used to provide a protective coating for underground pipe.
