Vinyl ester resins are produced by the reaction esterification between an epoxy resin and an unsaturated monocarboxylic acid.
Difference between polyester and vinylester resin.
Our 300 21 and 400 21 epoxy resins have a flexural strength of 17 500 psi.
But there are several key differences between epoxies and resins.
Vinyl esters also use peroxides e g.
Epoxy is extremely strong and has great flexural strength.
When higher strength bond and water resistance is required such as keel rudder repair or out board transom replacement use lbi s 302 isothalic polyester resin.
Differences between resins there are three main types of resins used for composite materials.
Ortho polyester isothalic polyester and vinylester resins are compatible they all have styrene commonly known as the fiberglass smell and chemically bond to one another.
Here s a quick breakdown on the differences between epoxy resin and polyester resin.
Epoxy is known for its higher bonding capabilities overall.
Polyester vinyl ester and epoxy resins.
Polyester resins are standard resin for composite construction.
An epoxy s relative strength can hold up to 2 000 lbs.
