Heat Resistant Vinyl Ester

Resistant vinyl ester for pipes to carry hot gases for reinforcement in dual laminates and for appli cations such as quench vessels.

Heat resistant vinyl ester.

Vinyl ester has fewer open sites in its molecular chain. Due to its high molecular weight and low permeability it will withstand exposure to a broad range of acids caustics and solvents. Flame retardant applications where translucency is required. This makes it much more resistant to water penetration hydrolysis which can cause osmotic blistering.

It is important to note that of the three vinyl ester resin will provide the highest corrosion resistance temperature resistance and elongation toughness. This is our premium line of corrosion resistant novolac epoxy based vinyl ester resins and includes high crosslink density high heat distortion products. Derakane 510n resin is a brominated epoxy novolac. 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.

Presented herein are a series of extremely high heat resistant vinyl ester resins which exceed the hdt s of today s commercially available high. Liquid resin properties cast mechanical properties laminate mechanical properties hard. Equipment where strong acids and bases are encountered. Inherent toughness provides fabrication advantages and resistance to both impact and thermal shock damage.

Vinyl ester resins. 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. Vinyl esters shrink less on curing which means that pre release of a laminate from a mold is less significant. A new high tem perature resistant vinyl ester has been developed with a heat distortion temperature of 330 f 165 c.

Their bromine content makes them tougher and more fatigue resistant than standard epoxy vinyl ester resins. Epoxy vinyl ester hetron 922 corrosion resistant to both strong acids and bases. Vinyl esters are more tolerant of stretching than polyesters. Epoxy vinyl ester resins that offer a high degree of fire retardance1.

They are very resistant to chemical attack by chlorine and bleach environments. Vinyl ester or vinylester is a resin produced by the esterification of epoxy resin with unsaturated monocarboxylic acid. Can be used as primer mid coat or finish coat in atmospheric and immersed environments. Novolac vinyl ester resins afford excellent corrosion resistance high structural properties and outstanding laminate capabilities at ambient and high temperatures.
