Vinyl ester resins are produced by the reaction esterification between an epoxy resin and an unsaturated monocarboxylic acid.
They were first developed for structural applications such as glass reinforced plastic radar domes on aircraft and graphite epoxy payload bay doors on the space shuttle.
Vinyl monomers are used in unsaturated polyester glass fibre reinforced artificial marble and gelcoat.
This thermoset material can be used as an alternative to polyester and epoxy materials as the thermoset polymer matrix in composite materials where its characteristics strengths and bulk cost are intermediate between polyester and epoxy.
Thus if a hard rigid thermoset is desired the divinyl ether concentration constitutes a higher percentage of the monomer mixture than in the case where a rubbery elastic thermoset resin is.
Methyl ethyl ketone peroxide mekp is one such hardening agent.
Thermosets are reactive systems like un saturated polyester epoxy polyurethane acrylics and uv sys tems.
Resins are bisphenol a diglycidyl ether dgeba and epoxy phenol novolac epn.
Ope 1 is used in high frequency printed circuit board due to its low dielectric characteristic after curing.
