Heat Resistant Vinyl Ester

Vinyl ester resins.

Heat resistant vinyl ester.

Inherent toughness provides fabrication advantages and resistance to both impact and thermal shock damage. Flame retardant applications where translucency is required. They are very resistant to chemical attack by chlorine and bleach environments. 408 1 2 408 vinyl ester validationdate technical data sheet chemflake special product description this is a glass flake reinforced vinyl ester coating.

It is an ultra high build extremely chemical resistant and fast curing barrier coating. Novolac vinyl ester resins afford excellent corrosion resistance high structural properties and outstanding laminate capabilities at ambient and high temperatures. Vinyl esters are more tolerant of stretching than polyesters. Vinyl esters shrink less on curing which means that pre release of a laminate from a mold is less significant.

Vinyl ester resin is considered a hybrid of polyester and epoxy meaning its handling characteristics properties and price generally fall just between the other two. Their bromine content makes them tougher and more fatigue resistant than standard epoxy vinyl ester resins. Liquid resin properties cast mechanical properties laminate mechanical properties hard. A new high tem perature resistant vinyl ester has been developed with a heat distortion temperature of 330 f 165 c.

Equipment where strong acids and bases are encountered. Resistant vinyl ester for pipes to carry hot gases for reinforcement in dual laminates and for appli cations such as quench vessels. Can be used as primer mid coat or finish coat in atmospheric and immersed environments. Vinyl esters have enhanced mechanical properties compared to polyesters with physical strength better impact and thermal shock resistance.

This makes it much more resistant to water penetration hydrolysis which can cause osmotic blistering. The highest performance vinyl esters achieve heat distortion temperatures hdt of 165 c which precludes their use as a matrix resin in the most demanding high heat applica tions. This is our premium line of corrosion resistant novolac epoxy based vinyl ester resins and includes high crosslink density high heat distortion products. Epoxy vinyl ester resins that offer a high degree of fire retardance1.

It is important to note that of the three vinyl ester resin will provide the highest corrosion resistance temperature resistance and elongation toughness. Vinyl ester or vinylester is a resin produced by the esterification of epoxy resin with unsaturated monocarboxylic acid. Due to its high molecular weight and low permeability it will withstand exposure to a broad range of acids caustics and solvents. Derakane 510n resin is a brominated epoxy novolac.
