Hexion's "fast curing" Epikote Resin TRAC 06170 resin has been used to produce a composite coil spring for the Audi A6 Avant 2.0 TDI Ultra. The spring is produced by S.ARA Composites SAS, which is part of the SOGEFI Group. Hexion's Epikote TRAC 06720 curable preform adhesive cures at 160 ° C to help maintain the integrity of the preform.
Hansen offers a series of optimized fast-curing epoxy resins, curing agents and preformed adhesives for many years, and maintains long-term cooperation with customers through structural composite projects.
"The performance advantages of epoxy resins can meet safety requirements and light weight goals. Suspension systems such as leaf springs and coil springs are better applications," said Francis Defoor, the global transportation division leader at Orient.
Hansen's Epikote Resin TRAC 06170 resin and Epikure curing agent TRAC 06170 are mainly developed for structural parts using RTM or wet compression molding. Depending on the size and complexity of the part, this combination shortens the production cycle to 1 min.
IkoEpikote Resin TRAC 06400 series is also suitable for fast curing prepregs. When curing at 130, the curing time is only 90s.
"The product portfolio enables shortened process cycles, fast demolding and perfect bonding of glass, carbon and aramid fibers." Defoor added that the secret is to redesign the resin's chemical composition and The "strict control" of the processing technology and the optimal balance of viscosity and reactivity are achieved.
Hansen's Epikote TRAC 06720 is a curable preformed adhesive that minimizes fiber deformation before or during injection. It is fully compatible with RTM's epoxy matrix, cures with the part, and allows the use of a small amount of pre-formed material, which is suitable for faster lamination and faster filling speeds because the fibers are firmly held by the adhesive Living.
It is said that an advanced German carmaker used Hexion's fast-curing epoxy resin for several structural parts of a sports car, including flat and more complex shapes.
