Vinyester Resin for Sheet Molding Compound

Product Description

MFE 711 is based on bisphenol-A epoxy resin, provides resistance to a wide range of acids, alkalis, bleaches and solvents used in many chemical processing industry applications.

Benefits & Properties:

Easier workability, good air drying.

Shorter gel-to-cure interval, reduced stress cracking

The resin's improved reactity properties often permit an increase in the lay-up thickness per session.

Higher elongation provides FRP equipment with increased toughness

Lighter color makes defects easier to see and correct while the resin is still workable.

Longer shelf life provides additional flexibility to fabricators in storage and handling.

 

 

Applications and Fabrication Techniques:

FRP storage tanks, vessels, ducts, and on-site maintenance projects, particularly in chemical processing and pulp and paper operations.

The resin is designed for ease of fabrication using hand lay-up, spray-up, filament winding, compression molding and resin transfer molding techniques, pultrusion and molded grating applications.

When properly formulated and cured, complies with FDA regulation 21 CFR 177.2420, covering materials intended for repeated use in contact with food.

Package & Storage:

200 kg per drum or 1000 kg per IBC

Drums - Store at temperatures below 25ºC. Storage life decreases with

increasing storage temperature. Avoid exposure to heat sources such

as direct sunlight or steam pipes. To avoid contamination of product

with water, do not store outdoors. Keep sealed to prevent moisture

pick-up and monomer loss.
