Heat Resistant Vinyl Ester

Vinyl ester resins.

Heat resistant vinyl ester. This makes it much more resistant to water penetration hydrolysis which can cause osmotic blistering. A new high tem perature resistant vinyl ester has been developed with a heat distortion temperature of 330 f 165 c. It is important to note that of the three vinyl ester resin will provide the highest corrosion resistance temperature resistance and elongation toughness. 408 1 2 408 vinyl ester validationdate technical data sheet chemflake special product description this is a glass flake reinforced vinyl ester coating.

Liquid resin properties cast mechanical properties laminate mechanical properties hard. Vinyl esters shrink less on curing which means that pre release of a laminate from a mold is less significant. Flame retardant applications where translucency is required. Vinyl esters have enhanced mechanical properties compared to polyesters with physical strength better impact and thermal shock resistance.

Their bromine content makes them tougher and more fatigue resistant than standard epoxy vinyl ester resins. 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. Due to its high molecular weight and low permeability it will withstand exposure to a broad range of acids caustics and solvents.

Vinyl ester has fewer open sites in its molecular chain. Equipment where strong acids and bases are encountered. Epoxy vinyl ester hetron 922 corrosion resistant to both strong acids and bases. Inherent toughness provides fabrication advantages and resistance to both impact and thermal shock damage.

Derakane 510n resin is a brominated epoxy novolac. Can be used as primer mid coat or finish coat in atmospheric and immersed environments. Vinyl esters are more tolerant of stretching than polyesters. They are very resistant to chemical attack by chlorine and bleach environments.

Novolac vinyl ester resins afford excellent corrosion resistance high structural properties and outstanding laminate capabilities at ambient and high temperatures. This is our premium line of corrosion resistant novolac epoxy based vinyl ester resins and includes high crosslink density high heat distortion products. Resistant vinyl ester for pipes to carry hot gases for reinforcement in dual laminates and for appli cations such as quench vessels. Epoxy vinyl ester resins that offer a high degree of fire retardance1.
