Abstract:
Methods, processes, compositions and systems for preventing leaching effects from water pipes (such as lead, steel and copper) having an inner diameter of at least approximately 12 mm. 2-part thermoset resin coating is applied to the inner surfaces of the pipes where the curing agent can be a phenol free and plasticizer free adduct type. The coating can reduce heavy metals, such as lead, from leaching from installed pipes to less than approximately 10 μg/L (10 ppb). When cured, specific leachates, Bisphenol A and Epichlorohydrin from the coatings will be (less than)<1 μg/L (1 ppb) with overall TOC levels measured at (less than)<2.5 mg/L (2.5 ppm). Pipes can be returned to service within approximately 24 hours, and preferably within approximately 4 hours. The methods, processes, compositions and systems can work with non-metallic pipes having metal valves and/or metal fittings.

Claim (Index 11):
The process of  claim 11 , wherein the resin is a 2-part thermoset resin composition with a base resin and the curing agent.
