Product Description

DERAKANE™ SIGNIA 411 is a bisphenol-A epoxy vinyl ester resin that, once fabricated into a composite part, resists a wide range of acids, alkalis, bleaches, and organic compounds used in chemical processing industry applications.

SIGNIA 411 is the next-generation evolution of our DERAKANE™ MOMENTUM 411-350, built on the same proven chemistry with improved secondary bonding, lower emissions, and a proprietary identification system for verifying built-to-spec equipment. For high-temperature service, see DERAKANE™ MOMENTUM 470-300; for fire retardancy, see DERAKANE™ MOMENTUM 510 C-350 HOI.

For Composite Manufacturers

● Designed to enhance secondary bonding and reduce or eliminate the need for surface preparation between laminate layers during initial production, cutting labor costs and producing a cleaner workplace

● Formulated for better wet-out, reduced gassing, and faster composite consolidation

● Prepared with an innovative styrene suppression system, giving a lower-odor environment with up to 35% emissions reduction based on the VSE test per 40 CFR Subpart WWWW Appendix A (the US Composites MACT Standard)

For Asset Owners

● Offers the proven technology and performance of legacy DERAKANE™ series resins, plus a unique, proprietary identification system confirming tanks, pipes, and other equipment are built as specified

● Extends service life of equipment designed for corrosive environments, postponing the need for replacement

● Facilitates design and operation under heavy loads

● Improves toughness and reduces cracking from cyclic temperature and pressure fluctuations or mechanical shocks during shipping, installation, and operation

Typical Liquid Resin Properties

Application

Suitable for fabricating FRP storage tanks, vessels, piping, ducts, and on-site maintenance projects, particularly in chemical processing and pulp and paper operations. Designed for ease of fabrication using hand lay-up, spray-up, and filament winding.

● When properly formulated and cured, complies with FDA regulation 21 CFR 177.2420 for repeated food-contact use

● Properly built laminates, including multi-step build-up, show good interlaminar adhesion

● Minimal to no resin excess between laminate layers is required for good secondary bonding — manufacturers should verify this with their own practices

● Addition of thixotropic agents and fillers can compromise corrosion resistance — contact ALTA Performance Materials before using them
