Essentially they comprise a base of polyester resin strengthened with epoxy molecules in the backbone of the molecular chain. 0 7 cc 20 drops. Vinyl esters also use peroxides e g. Crystic ve 679 03pa is a pre accelerated dcpd modified vinyl ester resin.

Vinyl ester resins offer increased strength corrosion resistance and durability and are used in a wide variety of applications. Titanium dioxide 13463 67 7 10 mg m3 no slack iron oxide 1317 61 9 10 mg m3 no. Ve 679 03pa is supplied with 2 catalyst triganox 249 introduction. While vinyl ester resins are classified as polyester based formulations they are actually an intermediate between a polyester backbone and epoxy terminations on the ends of the molecules.

It is a solution of methyl ethyl ketone peroxides and cumyl hydroperoxide in phlegmatizer. Methyl ethyl ketone peroxide mekp is an organic peroxide used in the marine industry. Vinyl ester resins are produced by the reaction esterification between an epoxy resin and an unsaturated monocarboxylic acid. Without mekp there will not be the needed chemical reaction that turns the liquid resin into a solid.
