Epoxy Vinyl Ester Chemical Resistance

To achieve the highest bond strength and water resistance use lbi s 901 vinylester resin.

Epoxy vinyl ester chemical resistance.

Epoxy vinyl ester resin that offers very high toughness impact and fatigue resistance and excellent adhesion. Epoxy vinyl ester resins also find uses in coatings particulalry for the marine building and construction industries due to their excellent corrosion and weathering resistance. They are based on bisphenol a epoxy resin and they provide resistance to a wide range of acids alkalis bleaches and solvents for use in many chemical processing applications. Vinyl esters have enhanced mechanical properties compared to polyesters with physical strength better impact and thermal shock resistance.

Derakane 8084 resin is an elastomer modified bisphenol a epoxy vinyl ester resin that offers very high toughness impact and. Chemical 1 2 630 633. Acetone nr nr s 3 s 3. Vinyl ester or vinylester is a resin produced by the esterification of epoxy resin with unsaturated monocarboxylic acid.

Derakane 411 series resinsare the globally recognized standard for epoxy vinyl ester resins. Vinyl ester chemical resistance. It is the most resistant resin in our portfolio against chlorine bleach and hot wet flue gas environments. When higher strength bond and water resistance is required such as keel rudder repair or out board transom replacement use lbi s 302 isothalic polyester resin.

However most are prepared solely with reactive vinly type monmomers. In some cases conventional solvents such as xylenes are also used. They offer excellent toughness and fatigue resistance. It is the resin of choice for demanding structural applications and as a primer for chemically resistant frp linings.

1 the degree of retardance achieved in properly formulated cured products made of these resins is most frequently. Vinylester is essentially a styrene modified epoxy resin.
