Vinyl Ester Resins

VINYL ESTER RESINS

Vinyl ester resins are produced by the reaction between an epoxy resin and an unsaturated monocarboxylic acid. One of their major advantages is that they offer better resistance to moisture absorption and hydrolytic attack than polyester. A vinyl ester skin between the gelcoat and the glass/polyester laminate or over the gel-coat, therefore tends to prevent the hydrolysis-induced osmotic blistering that fibreglass boat owners fear. Boat builder or owners retrospectively can incorporate this protection without having to go to the expense of using epoxy; though the latter constitutes an even more effective moisture barrier.

Properties:   PVES 901 is a bisphenol A type, clear yellowish coloured epoxy vinyl ester resin. It is a premium resin with improved reactivity and purity. It provides excellent corrosion resistance to a broad range of organic and inorganic acids, alkalis, oxidizing chemicals and salt solutions etc. It also provides very good mechanical strength such as tensile and flexural while incorporated with reinforcement such as glass fiber, carbon fiber or kevlar fiber etc. PVES 901 is designed to provide superior toughness with excellent fatigue resistance due to high heat distortion temperature.

Applications:  Chemical storage tanks, pipes, flue gas desulfurization systems (FGD), scrubbers, ducts, corrosion resistant flooring while incorporated with aggregates, waste water treatment systems, food storage tanks and pure water system, marine use for yachts and boats.
