711 Vinyl Ester Resin frp epoxy high temp bisphenol-a
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.
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.
● Lloyds’ approved in the name of 711
