8090

DERAKANE 8090 Epoxy Vinyl Ester Resin March 2005 A new addition to the family of DERAKANE resins DERAKANE 8090 epoxy vinyl ester resin is a high performance epoxy vinyl ester resin, with greatly improved mechanical properties. It is designed to offer increased flexibility and tensile properties along with exceptional impact resistance. Although this epoxy vinyl ester grade is mainly developed for structural composite applications, it also offers similar corrosion resistance like traditional flexible epoxy vinyl ester resins e.g., DERAKANE 8084 resin. Applications: DERAKANE 8090 epoxy vinyl ester resin can be used in most of the common application technologies associated with fiber reinforced plastic processing. Fabrication Techniques: Can be used in conjunction with all common fabricating techniques. Its combination of high reactivity and low viscosity make this resin an ideal candidate for a large number of processes ranging from hand lay-up to vacuum molding applications and pultrusion. Benefits: • Exhibits 40% increase in impact resistance if compared to traditional flexible vinyl ester resins. • Exceptional tensile elongation (at break). • Exceptional flexural properties (samples are not destroyed in the flexural test). • In combination with various types of fillers the resin shows a very good abrasion resistance when compared with standard epoxy vinyl ester resins e.g., DERAKANE 470-36 resin. • Shows a very good processability (excellent reactivity and impregnation). Such a combination of properties is unique. • A post cure of two hours at 80°C/ 176°F is in general sufficient to obtain the typical mechanical properties of this resin.
