Epoxy Vinyl Ester Chemical Resistance

However most are prepared solely with reactive vinly type monmomers.

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. Epoxy vinyl ester resin that offers very high toughness impact and fatigue resistance and excellent adhesion. To achieve the highest bond strength and water resistance use lbi s 901 vinylester resin. Derakane 411 series resinsare the globally recognized standard for epoxy vinyl ester resins.

They offer excellent toughness and fatigue resistance. In some cases conventional solvents such as xylenes are also used. It is the resin of choice for demanding structural applications and as a primer for chemically resistant frp linings. Acetone nr nr s 3 s 3.

1 the degree of retardance achieved in properly formulated cured products made of these resins is most frequently. Vinyl ester chemical resistance. Vinyl ester or vinylester is a resin produced by the esterification of epoxy resin with unsaturated monocarboxylic acid. Standard epoxy vinyl ester resins are limited to 220 250 of 104 121 oc in most applications.

Vinyl esters have enhanced mechanical properties compared to polyesters with physical strength better impact and thermal shock resistance. 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. 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 510n resin is brominated epoxy novolac vinyl ester resin that offers a high degree of fire retardance1.

Due to its high molecular weight and low permeability it will withstand exposure to a broad range of acids caustics and solvents. Chemical 1 2 630 633.
