AOC responds with Vipel resin consistency, excellent wetting, and formulations adapted for specific process conditions — from liner-wetting under controlled shop conditions to on-site wetting in conditions established by nature. For the long term, a new CIPP system is expected to provide a service life that often exceeds the life of the original system. AOC responds with a range of Vipel technologies that allow the user to balance cost and performance requirements. Vipel isophthalic polyester resins for CIPP set the standard for most rehabilitation projects around the world.
