Product Description

1 Brief Introduction
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.
 
2 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.

3 Benefits & Properties  
Easier workability, good air drying. Shorter gel-to-cure interval, reduced stress cracking, The resin's improved reactivity 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.
