Epoxy Vinyl Ester Chemical Resistance

However most are prepared solely with reactive vinly type monmomers.

Epoxy vinyl ester chemical resistance.

Derakane 8084 resin is an elastomer modified bisphenol a epoxy vinyl ester resin that offers very high toughness impact and. Standard epoxy vinyl ester resins are limited to 220 250 of 104 121 oc in most applications. It is the most resistant resin in our portfolio against chlorine bleach and hot wet flue gas environments. Due to its high molecular weight and low permeability it will withstand exposure to a broad range of acids caustics and solvents.

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. Vinyl esters have enhanced mechanical properties compared to polyesters with physical strength better impact and thermal shock resistance. Derakane 411 series resinsare the globally recognized standard for epoxy vinyl ester resins. They offer excellent toughness and fatigue resistance.

1 the degree of retardance achieved in properly formulated cured products made of these resins is most frequently. Chemical 1 2 630 633. 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. Derakane 510n resin is brominated epoxy novolac vinyl ester resin that offers a high degree of fire retardance1.

To achieve the highest bond strength and water resistance use lbi s 901 vinylester resin. Acetone nr nr s 3 s 3. It is the resin of choice for demanding structural applications and as a primer for chemically resistant frp linings. 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.

Vinyl ester or vinylester is a resin produced by the esterification of epoxy resin with unsaturated monocarboxylic acid. Epoxy vinyl ester resin that offers very high toughness impact and fatigue resistance and excellent adhesion.
