Epoxy Vinyl Ester Chemical Resistance

Derakane 510n resin is brominated epoxy novolac vinyl ester resin that offers a high degree of fire retardance1.

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

Vinyl esters have enhanced mechanical properties compared to polyesters with physical strength better impact and thermal shock resistance. Standard epoxy vinyl ester resins are limited to 220 250 of 104 121 oc in most applications. 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. 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. To achieve the highest bond strength and water resistance use lbi s 901 vinylester resin. 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. Derakane 411 series resinsare the globally recognized standard for epoxy vinyl ester resins.

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. Vinylester is essentially a styrene modified epoxy resin. It is the resin of choice for demanding structural applications and as a primer for chemically resistant frp linings. It is the most resistant resin in our portfolio against chlorine bleach and hot wet flue gas environments.
