Interplastic also offers tough, low VOC, modified vinyl ester resins (MVR). The CoREZYN MVR8013 LH series and MVR8011 series of resins are designed for marine, tooling and general composite applications. They features excellent physical characteristics, surface quality and blister resistance. These resin series also give you the toughness and strength of traditional vinyl esters plus compliance with current EPA regulations. Numerous marine composite manufacturers use the vacuum infusion process (VIP) to construct bulkheads, hulls and other laminates. The CORVEX169-826 is a promoted, low viscosity vinyl ester, designed especially for vacuum infusion process. Det Norske Veritas (DNV) certified the resin and the CoREZYN C-1037-NCU clear iso/NPG® gel coat for this process. DNV is a certifying organization similar to Lloyds of London.
