Vinyl ester and epoxy uv resistance.

Vinyl esters also use peroxides e g. Epoxy resin is an ideal resin for high performance and light weight parts. It provides some flex to help resist impact damage and also has uv inhibitors to protect the water clear appearance. More fatigue resistant than standard epoxy vinyl ester resins.

Vinyl ester or vinylester is a resin produced by the esterification of epoxy resin with unsaturated monocarboxylic acid. It exhibits a corrosion resistance similar to derakane 470 resins in most environments. Epoxy can be applied over polyester and vinyl ester resin for repairs etc but not vice versa. Essentially they comprise a base of polyester resin strengthened with epoxy molecules in the backbone of the molecular chain.

This is a remarkably clear vinyl ester. Epoxy vinyl ester resins also find uses in coatings particulalry for the marine building and construction industries due to their excellent corrosion and weathering resistance. Regarding costs vinyl ester resin is more expensive than polyester resin but cheaper than epoxy resin. It is a water clear uv and impact resistant resin.

Vinyl esters have enhanced mechanical properties compared to polyesters with physical strength better impact and thermal shock resistance. Epoxy is not on its own uv resistant. Heat resistant vinyl ester resins for composite applications john e. Cannot be used on eps styrofoam.

It is the base resin in our solarez extreme putty. Derakane 510n resin is brominated epoxy novolac vinyl ester resin that offers a moderate degree of fire retardance1. Vinyl ester resins are produced by the reaction esterification between an epoxy resin and an unsaturated monocarboxylic acid. Vinyl ester epoxy uv cure laminating resin is an extremely tough corrosion resistant resin with great adhesion.

Epoxy cures fully when applied as a thin film making it ideal for adhesive applications. It is also useful in hot wet fluegas environments where. It exhibits a corrosion resistance similar to derakane 470 resins in most environments. Epoxy is very resistant to wear cracking peeling corrosion and damage from chemical and environmental degradation.
