Product Description

MFE 790 EPOXY  VINYL ESTER RESIN

MFE 700 range, the 2 nd generation of MFE, it set to raise the standard even higher. They all based on a technology that delivers high temperature resistance, good wet ability and process ability, standard catalyst system.
MFE 790 is PU modified epoxy vinyl ester resin which own the mechanical properties of vinyl ester resin and meanwhile provide higher toughness and elongation.

Properties & Benefits
• Resistance to most acid, salt, alkali and solvents
•The flexibility, tensile properties and impact strength have been greatly improved by big molecular design and the impact strength has been increased by 40%compared with standard flexible epoxy vinyl ester resin.
• Tensile elongation at break is 12%
• Good processability and abrasion resistance
•Excellent dynamic load resistance, good impact resistance  under  cyclic  temperature,  pressure fluctuation and mechanical impact conditions, and high strength retention rate.
Applications
• MFE 790 epoxy vinyl ester resin can be used in most of the common application technologies associated with fiber reinforced plastic process with process hand lay-up, spray up, filament winding, pultrusion and infusion/RTM
