Vinyl ester
From Wikipedia, the free encyclopedia
Vinyl Ester, or Vinylester, is a resin produced by the esterification of an epoxy resin with an unsaturated monocarboxylic acid. The reaction product is then dissolved in a reactive solvent, such as styrene, to a 35 - 45 percent content by weight.
It can be used as an alternative to polyester and epoxy materials in matrix or composite materials, where its characteristics and strengths are superior to that of polyester, however inferior to epoxy.
In homebuilt airplanes, the Glasair and Glastar kit planes made extensive use of vinylester-reinforced fiberglass structures. It is a common resin in the marine industry due to its increased corrosion resistance and ability to withstand water absorption.
