The epoxy putty is a two part epoxy activated by kneading the inner and outer core until colors are fully blended. Working time is about two minutes, sets hard in about 20 minutes, and cures completely in about one hour. HS PIPE WRAP is coated with a polyurethane resin formula designed for activation by immersion in water. When activated, working time is about two to three minutes. The initial set occurs in about five minutes.
Cure time increases with thickness of application.
Set time accelerates dramatically at higher temperatures and slows when cooler. After cure, ends may be trimmed and cleaned for appearance purposes, if desired. As with any adhesive application, preparation is very important. Remove ALL pressure from the pipe, including gravity fed drip. Remove oil, grease, loose rust scale, sealant tape, and paint from repair area.
