Lower Viscosity CORVE8100 Series

This line of vinyl ester resins are lower intrinsic viscosity versions of the CORVE8300 series, corrosion resistant vinyl ester resins for use in centrifugal casting, pultrusion, vacuum infusion, and RTM applications, and are well suited for use in fabricating tanks, pipe and process equipment, as well as other applications. When cured, they exhibit physical properties similar to the CORVE8300 line. CORVE8100-50 is our workhorse product. It is a nonpromoted, low viscosity, corrosion resistant vinyl ester resin for use in vacuum infusion and RTM applications. CORVE8100-50 is manufactured from ingredients listed as acceptable in the FDA Code of Federal Regulation Title 21, CFR 177.2420. This resin may be safely used as a component of articles intended for single or repeated use in contact with food as prescribed in the regulation.

Since most of the applications and processes in this market segment are very unique, please contact us so that we can customize a resin for you.

CORVE8434

This is a nonpromoted, fire retardant vinyl ester resin for use in the manufacture of fiberglass parts with excellent dimensional stability that meets the transportation applications fire and smoke requirements. A fiberglass reinforced panel with 60-70% reinforcement by weight will have an ASTM E162 flame spread rating of less than 25 and ASTM E662 smoke density of less than 200 after 4 minutes in the flaming mode. CORVE8430 is a spray up resin. while CORVE8434 is formulated for infusion applications.

MVR8071

A promoted, non-thixotropic, vinyl ester/polyester resin blend, MVR8071 is designed for the fabrication of large parts using the vacuum infusion process (VIP). It is our workhorse marine infusion resin that provides fast fill times and excellent cosmetics.

MVR8015

MVR8015 is a modified vinyl ester resin for vacuum bagging, infusion and other high toughness applications. It is available unpromoted and pre-promoted.
