Epoxy Vinyl Ester Chemical Resistance

Epoxy vinyl ester resin that offers very high toughness impact and fatigue resistance and excellent adhesion.

Epoxy vinyl ester chemical 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. Vinylester is essentially a styrene modified epoxy resin. Derakane 411 series resinsare the globally recognized standard for epoxy vinyl ester resins. In some cases conventional solvents such as xylenes are also used.

Derakane 510n resin is brominated epoxy novolac vinyl ester resin that offers a high degree of fire retardance1. Chemical 1 2 630 633. Vinyl ester or vinylester is a resin produced by the esterification of epoxy resin with unsaturated monocarboxylic acid. 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.

To achieve the highest bond strength and water resistance use lbi s 901 vinylester resin. They offer excellent toughness and fatigue resistance. 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. 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. Vinyl ester chemical resistance. Due to its high molecular weight and low permeability it will withstand exposure to a broad range of acids caustics and solvents.

Vinyl esters have enhanced mechanical properties compared to polyesters with physical strength better impact and thermal shock resistance. Acetone nr nr s 3 s 3.
