AOC (Collierville, Tenn., USA) has expanded its cured-in-place pipe (CIPP) resins lineup with the addition of Vipel L085-PPA epoxy novolac vinyl ester, designed for applications that need resistance to aggressive chemical solutions and high heat. It is said to provide corrosion resistance, durability and toughness in formulation packages designed for CIPP processing. The resin’s epoxy novolac chemistry reportedly provides good resistance to acids, bases and many organic solvents. It is said to perform well at high temperatures, with a heat distortion temperature (per ASTM D648) of 300°F/149°C.
