Epoxy resin should be used.

Vinyl ester resin vs fiberglass. Try to store the resin in a cool dry place or refrigerate do not freeze it to extend the life of the resin. Regarding costs vinyl ester resin is more expensive than polyester resin but cheaper than epoxy resin. Resin has a short shelf life. It is water resistant.

Essentially they comprise a base of polyester resin strengthened with epoxy molecules in the backbone of the molecular chain. 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.

Excellent secondary chemical bond to polyester laminate when making repairs or when strength and stiffness are important. It can be used with. If you need a fiberglass contractor please call chris at 860 373 3938. 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.

These are epoxy vinylester polyester resins each has different. It s heat resistant and blended for durability. 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. It is important to note that of the three vinyl ester resin will provide the highest corrosion resistance temperature resistance and elongation toughness.

Call for specific applications. Vinyl ester has a shelf life of 3 months. Highly water and chemical resistant. Vinyl ester resin.

When using vinyl ester resin be sure to use it quickly after purchasing. Both polyester and vinyl ester resins will react and build in molecular weight to a solid waxy resin and be mostly unusable in that waxy state. Vinyl ester is formulated for maximum corrosion resistance to most fuels vapors and chemicals. Epoxy resin is an ideal resin for high performance and light weight parts.

Normal viscosity for vinyl esters is less than polyester about 500 centipoise when cut in styrene monomer. The hardener catalyst for vinyl ester resin and polyester resins is mekp. Vinyl ester resin is considered to be a hybrid of polyester and epoxy resins meaning its handling characteristics properties and even price generally fall just between the two. Vinyl ester resin cures with a tack.

Vinyl esters also use peroxides e g. There are three main types of resins used today for use with carbon fiber fiberglass and aramid kevlar.
