Heat Resistant Vinyl Ester

Vinyl ester has fewer open sites in its molecular chain.

Heat resistant vinyl ester.

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. Vinyl esters have enhanced mechanical properties compared to polyesters with physical strength better impact and thermal shock resistance. Derakane 510n resin is a brominated epoxy novolac.

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. Liquid resin properties cast mechanical properties laminate mechanical properties hard. Equipment where strong acids and bases are encountered.

Vinyl ester resins. Their bromine content makes them tougher and more fatigue resistant than standard epoxy vinyl ester resins. Vinyl ester or vinylester is a resin produced by the esterification of epoxy resin with unsaturated monocarboxylic acid. Vinyl esters shrink less on curing which means that pre release of a laminate from a mold is less significant.

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. Epoxy vinyl ester hetron 922 corrosion resistant to both strong acids and bases. Resistant vinyl ester for pipes to carry hot gases for reinforcement in dual laminates and for appli cations such as quench vessels.

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. Vinyl esters are more tolerant of stretching than polyesters. It is important to note that of the three vinyl ester resin will provide the highest corrosion resistance temperature resistance and elongation toughness.

This makes it much more resistant to water penetration hydrolysis which can cause osmotic blistering. 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. Inherent toughness provides fabrication advantages and resistance to both impact and thermal shock damage. A new high tem perature resistant vinyl ester has been developed with a heat distortion temperature of 330 f 165 c.
