1i <br />Resin Descriptions <br />Novolac Vinyl Ester Resins <br />Novalacvinyl esters are based on use of multi -functional <br />novolac epoxy versus a standard and more commonly <br />used bisphenol-A epoxy. This increases the crosslink <br />density and corresponding temperature and solvent <br />resistance. <br />DION® Impact 9400 Series provides good corrosion <br />resistance, including solvents. Due to reactivity, shelf <br />life is limited to three months. <br />Elastomer -Modified Vinyl Ester Resins <br />Inclusion of high performance and special functional <br />elastomers into the polymer backbone on a vinyl ester <br />allows exceptional toughness. <br />DION® 9500 Series are non -accelerated rubber modif- <br />ied vinyl esters that possess high tensile elongat- <br />ion, good toughness, low shrinkage, and low peak <br />exotherm. They are well-suited for dynamic loads and <br />demonstrate excellent adhesion properties. Corros- <br />ion resistance is good, but limitations occur with <br />solvents or other chemicals which display swelling <br />with rubber. DIONO 9500 is well-suited for hand and <br />spray lay-up applications and other fabrication tech- <br />niques. It may also be considered for use as a primer <br />with high density PVC foam or for bonding FRP to <br />steel or other dissimilar substrates. <br />Bisphenol-A Fumarate Polyester Resins <br />Bisphenol fumarate polyester resins were among the <br />earliest and most successful premium thermosetting <br />resins to be used in corrosion resistant composites. They <br />have an extensive history in challenging environments <br />since the 1950's. Thousands of tanks, pipes, chlorine <br />cell covers, bleach towers, and scrubbers are still in <br />service throughout the world. <br />Bisphenol fumarate resins typically yield rigid, high <br />crosslink density composites with high glass transition <br />temperatures and heat distortion properties. These <br />attributes enable excellent physical property retention at <br />temperatures of 300° F and higher. Bisphenol fumarate <br />resins also have good acid resistance which is typical <br />for polyesters, but unlike other polyesters they also <br />display excellent caustic and alkaline resistance as well <br />as suitability for bleach environments. <br />All of the bisphenol fumarate resins have excellent <br />stability with a minimum shelf life of six months. <br />DION® 382* Series (Formerly Atlac® 382) are bisphe- <br />nol fumarate resins with a long, world-wide success <br />history.
