Product Description

Product Description

REL 411 Epoxy Vinyl Ester Resin

REL 411 epoxy vinyl ester resin is based on bisphenol-A epoxy resin and provides resistance to a wide range of acids, alkalis, bleaches, and organic compounds for use in many chemical processing industry applications.REL vinyl ester resins are a new generation of resins that can be used to improve fabrication efficiency and product quality.Their lighter color makes defects easier to see and correct while the resin is still workable. The resin's improved reactivity properties often permit an increase in the lay-up thickness per session. The longer stability provides additional flexibility to fabricators in storage and handling.

Features & Applications

Features:

1. Tolerates heavy design loads without causing failure due to resin damage therefore can work with large weight-bearing equipment with confidence
2. Excellent elongation and toughness provides FRP products with better impact resistance and less cracking due to cyclic temperature,pressure fluctuations, and mechanical shocks providing a safety factor against damage during process upsets or during shipping installation.
3. High solid content, with excellent mechanical strength and excellent toughness, the composite products made from it shows excellent long-term heat resistance, and  high dynamic load bearing performance;
4. Excellent toughness, crack resistance, higher heat resistance temperature, excellent strength retention at high temperature.

 

Applications:
REL 411 resin  is suitable for fabricating FRP storage tanks, vessels, ducts, and on-site maintenance projects,particularly in chemical processing and pulp and paper operations.REL 411resin 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.An alternate viscosity, optimized for some vacuum infusion processes, is available for customized process  in viscosity and gel time of our resins.
