Vinyl ester resin

[1] The "vinyl" groups refer to these ester substituents, which are prone to polymerize and thus an inhibitor is usually added.

The diester product is then dissolved in a reactive solvent, such as styrene, to approximately 35–45 percent content by weight.

In homebuilt airplanes, the Glasair and Glastar kit planes made extensive use of vinylester fiberglass-reinforced structures.

It is a common resin in the marine industry due to its corrosion resistance and ability to withstand water absorption.

For laminating process, vinyl ester is usually initiated with methyl ethyl ketone peroxide.
