Vinyl esters also use peroxides e g.
Epoxy resin vs vinyl ester resin.
Cloth and polyester resin.
There is a choice of three different hardeners.
It is important to note that of the three vinyl ester resin will provide the highest corrosion resistance temperature resistance and elongation toughness.
It adds excellent strength rigidity adhesion water and chemical resistance.
Specifically proper cure of vinyl ester resins and a 15 year study of the effective use of permeation barriers in marine composites to prevent corrosion and blistering.
Here s a different way to look at epoxy resin vs.
Vinyl ester resin is considered a hybrid of polyester and epoxy meaning its handling characteristics properties and price generally fall just between the other two.
Has some great papers on this which i am quoting from.

Epoxy adheres to wood much better than polyester does.
Epoxy resin comes in two parts.
Over the past decade carbon fiber technology has greatly expanded thanks to new more streamlined manufacturing processes.
To cover wood a laminate using epoxy resin and 10 oz cloth will yield a much better job than 10 oz.
Vinyl ester resins are produced by the reaction esterification between an epoxy resin and an unsaturated monocarboxylic acid.
These new methods create automotive and motorcycle parts which are stronger and more impact resistant than steel and weigh 1 4th less.
What are epoxy vinylester polyester resins.
Vinylester is essentially a styrene modified epoxy resin.
The b side is typically the hardener side.
The resin side is typically designated as the a side.
One of the only downsides to epoxy is that it is more expensive than polyester and vinyl ester resin.
Essentially they comprise a base of polyester resin strengthened with epoxy molecules in the backbone of the molecular chain.
Plus he has 25 years of making all kinds of cool stuff and is an expert wood crafter.
Using epoxy you can improve the laminate properties with a post cure almost always.
