Vinyl Ester Resin Gelcoat

Vinyl ester gelcoat epocom is an epoxy bisphenol a vinyl ester urethane gelcoat additived and modified to have and excellent adhesión and compatibility with epoxy resins.

Vinyl ester resin gelcoat.

Vinyl earthenware coating systems are often preferred in the industrial field over alternative systems such as polyester resins. If you rolled or sprayed polyester or vinyl ester resin on a surface of concrete steel or any substrate it would not hold water. Vinyl ester resins are produced by the reaction esterification between an epoxy resin and an unsaturated monocarboxylic acid. Reichhold is one of the world s largest suppliers of unsaturated polyester and vinyl ester resins for composites applications.

It dries outward and under a microscope has small holes. Resin has a short shelf life. Vinyl esters also use peroxides e g. Fiberlay has over 50 years of experience as an industry leader and worldwide distributor of composite raw materials and equipment.

Reichhold offers the broadest manufacturing presence to produce a complete line of resin products gelcoats and bonding pastes for customers who fabricate composite products ranging from bathtubs to wind turbine blades. When using vinyl ester resin be sure to use it quickly after purchasing. Epoxy resin should be used. Essentially they comprise a base of polyester resin strengthened with epoxy molecules in the backbone of the molecular chain.

Can be pigmented 2oz 8oz per gallon. Even when you use a polyester or vinyl ester with a fiberglass matting it still will not hold water. Its use is limited to the construction of high performance power boats where vinylesters increased bond strength has helped eliminate bonding problems with core materials vinylester resin is also used as a great water barrier when mixed properly with glass. The styrene in the polyester or vinyl ester resin will melt it.

Vinyl ester has a shelf life of 3 months. Try to store the resin in a cool dry place or refrigerate do not freeze it to extend the life of the resin. Over 15 000 products sold online. You must apply a gel coat to contain the water.

Technical characteristics and properties of gelcoat vinyl ester. It is used where greater abrasion and water resistance is required. This gelcoat is tougher and adheres better than standard isothalic polyester gelcoat for re gelcoating. This gelcoat is specially formulated for both tooling and parts manufacturing combining the vinyl ester technology with epoxy resin laminates.

The reason for this preference is that vinyl ester resins have a higher chemical mechanical and above all thermal resistance. In terms of physical properties and cost vinylester resin is a compromise between low cost polyesters and epoxy resins.
