Abstract
A coating composition for forming a water-resistant coating on fiber-reinforced articles such as rods or cables. The composition comprises an aqueous solution of a superabsorbent water-soluble polymer, a viscosity modifying agent, and optionally a lubricant. The coating formed by applying the composition effectively prevents the treated surface from water-permeation damage by absorbing water that contacts the layer containing the superabsorbent component.
Claims23
A coating composition for a reinforcing article comprising a superabsorbent water-soluble polymer precursor in aqueous solution.
A coating formed on the surfaces of a reinforcing article, comprising a superabsorbent water-soluble polymer.
A reinforcing article having a coating comprising:
- a superabsorbent polymer;
- a viscosity modifying agent;
- and
- a binder.
A method of forming a superabsorbent, water-resistant coating on the surface of a reinforced fiber-containing article comprising:
- a) preparing a liquid coating composition comprising a superabsorbent water-soluble polymer that absorbs and desorbs water when the coating is exposed to an aqueous or moisture-containing environment and a viscosity modifying agent;
- b) applying the liquid coating composition to the surface of the article to form a liquid coating;
- and
- c) drying and curing the liquid coating to form a water-absorbing, water-resistant coating layer on the surface of the article.
An aqueous coating composition comprising:
- a superabsorbent polymer precursor;
- a viscosity-modifying agent;
- and
- a binder.
