MVR8071 is a promoted, non-thixotropic, vinyl ester/polyester resin blend. It is designed for the fabrication of thick parts
using the vacuum infusion process (VIP). MVR8071 is designed to provide a low exotherm in thick parts while maintaining
an excellent degree of cure.

FEATURES BENEFITS
Low Viscosity Rapid filling of parts
Low Exotherm/Low Shrinkage Improved surface quality
Excellent Fiberglass Wet-Out High laminate physical properties
Good Resin Cure Improved resistance to post-cure

*Gel time and reactivity will vary due to the type and concentration of Free Radical Initiator (catalyst), shop temperature, humidity, and type of fillers used. In order to meet
your individual needs, consult our technical sales representative for assistance. If using methyl ethyl ketone peroxide (MEKP) to gel and cure CoREZYN vinyl ester resins,
we recommend only these three brands: Cadox L-50a (Nouryon), Luperox DHD-9 (Arkema), and Norox MEKP-925 (United Initiators). These must be used at the
appropriate percentage and suitable temperature. Contact your Interplastic Corporation representative for assistance.
