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 1):
A process for coating interior surfaces of non-metallic water pipes having at least one metal fitting, having drinking water passing through the pipes, comprising the steps of:\n providing a thermoset resin with a curing agent having amine adducts that are phenol free and plasticizer free; coating interior surfaces of the non-metallic water service pipes and the at least one metal fitting with the thermoset resin as a barrier coating; curing the barrier coating to return the non-metallic water service pipes to service; and reducing lead levels leaching into the drinking water from the at least one metal fitting in the non-metallic water service pipes to less than 10 \u03bcg/L (10 ppb).
