Thermal- and chemical-resistant acid protection coating material and spin-on thermoplastic adhesive

A composition useful as an adhesive or protective coating, said composition comprising from about 10-40% by weight of a hydrocarbon resin and from about 1-7% by weight of a rubber dispersed or dissolved in a solvent system, said percentages by weight being based upon the total weight of the composition taken as 100% by weight, said composition being free of surfactant.

A composition useful as an adhesive or protective coating, said composition consisting essentially of from about 10-40% by weight of a hydrocarbon resin and from about 1-7% by weight of a rubber dispersed or dissolved in a solvent system, said percentages by weight being based upon the total weight of the composition taken as 100% by weight.

A method of using a composition, said method comprising the step of applying the composition to a substrate so as to form a layer of the composition on the substrate, said composition comprising from about 10-40% by weight of a hydrocarbon resin and from about 1-7% by weight of a rubber dispersed or dissolved in a solvent system, said hydrocarbon resin and rubber percentages by weight being based upon the total weight of the composition taken as 100% by weight, wherein said solvent system comprises at least about 95% by weight of a single solvent, said single solvent percentage by weight being based upon the total weight of the solvent system taken as 100% by weight.

The combination of:

• a substrate having a surface;
• and
• a cured or dried layer adjacent said substrate surface, said layer being formed from a composition comprising a hydrocarbon resin and a rubber dispersed or dissolved in a solvent system, wherein said solvent system comprises at least about 95% by weight of a single solvent, said single solvent percentage by weight being based upon the total weight of the solvent system taken as 100% by weight.
