Novolac High Temperature Vinyl Ester Resin

This range of MFE Novolac Vinyl Ester resins offer excellent resistance to high temperatures, retaining their much of their physical at these elevated temperatures.  Additionally they display excellent resistanc to solvents and oxidising accids.  Please consult with RF staff or check the corrosion guide to review recommended products for the application performace requirements.

Please read the Safety Data Sheet.

Resin Storage

Vinyl ester resins should be stored in a cool, dry place out of direct sunlight, the storage temperatures should be maintained below 25°C and it should be kept away from all sources of heat which might create localized hot spots.

The shelf life may be shortened when improper storage or transportation has occured, with resulting polymerization. Exposure to direct sunlight or other sources of high temperature can lead to dangerous exotherms, with rapid polymerization.

Copper and alloy containing copper should be avoided contact the resin.   Vinyl Ester Resins should be stored separately from oxidizing materials, peroxides and metals.

Shelf life is 3 months from RF's manufacturing date.
