Elastomeric Bisphenol A Epoxy Vinyl Ester Resin
Product Description
The AOC Vipel® F017 series is a styrene-soluble, elastomer-modified bisphenol A-type epoxy vinyl ester resin. Vipel® F017-AAA is a non-pre-accelerated, non-thixotropic resin.
Main Applications
The Vipel® F017 series is designed as a primer for bonding glass-fiber-reinforced composites to steel, concrete, and other substrates.
Performance Characteristics
Low volatile organic compound (VOC) content
All versions contain less than 40% (by weight) styrene.
Bonding
The Vipel® F017 series is designed as a primer for bonding glass-fiber-reinforced composites to steel, concrete, and other substrates.
Resilience
The Vipel® F017 series improves interlaminar adhesion and can be used in composite materials requiring greater flexibility.
General-Purpose
Suitable for various composite forming processes, such as hand lay-up, spray-up, and filament winding.

The typical values listed here should not be construed as technical specifications.The gel times shown are typical values but may be affected by catalyst, accelerator, and polymerization inhibitor concentrations, as well as resin, mold, and shop temperature. Gelation characteristics may vary with different types of initiators and under conditions of extremely
high humidity. Pigments and/or fillers may delay or accelerate gelation.Manufacturers are advised to verify gelation characteristics using a small amount of resin under actual operating conditions prior to use.
