REL 411 is a vinyl ester resin based on a standard bisphenol A epoxy backbone, specifically designed for demanding corrosion-resistant equipment applications. REL 411 Standard Bisphenol A Vinyl Ester Resin combines the excellent chemical resistance of epoxy resins with the good processing characteristics of unsaturated polyester resins. This resin offers excellent processing properties, ensuring smooth operation during the impregnation of reinforcing materials, lamination, and curing.

Furthermore, its superior batch-to-batch stability and consistency guarantee highly predictable and reliable performance in the final product, making it an ideal matrix material for manufacturing corrosion-protective linings and structural components such as chemical storage tanks, pipelines, and scrubbers.

Typical geltimes(2) using NOROX(3) MEKP-925H(4) catalyst (MEKP) and Cobalt Naphthenate or Octoate-6%(5)(Cobalt6%), Diethylaniline(7)(DEA) and 2,4-Pentanedione (2,4-P)

(2) Thoroughly test any other materials in your applications before full-scale use. Geltimes may vary dueto the reactive nature of these materials. Always test a small quantity before formulating large quantities

(4) NOrOx MEKP-925H content MEKP. Use of other MEKP catalystsor additives may result in different gel times.
(5) Use of cobalt octoate, especially in combination with 2.4-P can result in 20-30% slower gel times
(6) phr= parts per hundred resin molding compound
(7) For pre-acceleration for prolonged storage (e.g. formulation of lining or flooring systems) either avoidDIMA Or DEA. or use DEAA (DiEthyl-AcetoAcetamide). For further information, please contact REALLAND.

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 longterm heat resistance, and high dynamic load bearing performance;
4. Excellent toughness, crack resistance, higher heat resistance temperature, excellent strength retention at high temperature.
