3 Since 1957 we ve assisted reinforced plastics composites manufacturers and the industries that use reinforced plastics build better, stronger, tougher, and longer-lasting products. In 1959, we introduced a line of isophthalic and orthophthalic polyester Resins with outstanding laminating, casting and molding capabilities. At about the sa me time, we developed a line of top-performing gel coats for a wide variety of applications. Today, Interplastic gel coats give you extremely durable finishes for a brilliant surface in whatever color you choose. In 1976, we announced our line of epoxy-based Vinyl Ester Resins that have set the standard for the industry. In extremely challenging environments that require superior physical performance and corrosion resistance, Interplastic s CoREZYN Vinyl esters consistently outperform the competition. CoREZYN Vinyl Ester Resins (designated CORVE ) are a family of liquid thermosetting Resins developed for the production of fiber-reinforced plastics.

4 They are an ideal choice for severe applications, particularly in highly corrosive environments. The Vinyl Ester products exhibit similar strength characteristics to epoxy, but they are less expensive and much easier to handle. There is a wide variety of Resins available within our Vinyl Ester family to meet a broad range of design and engineering needs, and all of them possess corrosion resistance and exceptional physical properties.

5 Resin Navigator 6 Corrosion Resistant Vinyl Ester Resins Corrosion Resistant Vinyl Ester Resins Bisphenol-A-Epoxy Vinyl esters CORVE8300 Series High Performance This is our standard, high performance line of products, showing excellent resistance to acids, alkalies, and oxidizing chemicals, with outstanding toughness and fa tigue properties. These are well suited for use in fabricating tanks, pipe and process equipment. CORVE8300 This is the most versatile and widely used Vinyl Ester in our line. It can be used in filament winding, hand lay-up, BMC match-metal-die molding, pultrusion, tank lin ings and coatings where outstanding corrosion resistance is required. This resin has a viscosity of 500 cps and contains 45% styrene. Different viscosities and varying styrene levels are available. FDA/USDA Approvable: This non-promoted resin is manufactured from materials listed in Title 21 of The Code of Federal Regulations and is suitable for use as described therein.

6 CORVE8301 A promoted version of CORVE8300 for field applications where it is undesirable to add promoters. Gel time of 15 - 20 minutes. CORVE8300-35 35% styrene version, with 2500 cps viscosity. CORVE3000-40 40% styrene version, with 1200 cps viscosity. CORVE8300-50 50% styrene version, with 275 cps viscosity. CORVE8360 MACT co mpliant, Low HAP analog of CORVE8300. Outstanding corrosion resistance and physical properties with 500 cps and 34% or less styrene. CORVE8361 A promoted version of CORVE8360, for field applications where it is undesirable to add promoters. In the world s most intense applications, CoREZYN Vinyl esters are top performers. CORVE8300 LH A series of Low HAP versions of our CORVE8300, with versions available at 30%, 35% and 40% styrene. 7 Corrosion Resistant Vinyl Ester Resins Bisphenol-A-Epoxy Vinyl esters CORVE8100 Series Lower Viscosity A lower molecular weight and lower intrinsic viscosity version of the CORVE8300 line.

7 The lower viscosity makes these products ideal for centrifugal casting and resin transfer molding. When cured, they exhibit physical properties similar to the 8300 line. CORVE8100 This resin contains 50% styrene and has a nominal viscosity of 100 cps. FDA/USDA Approvable Laminates: This non-promoted resin is manufactured from materials listed in Title 21 of The Code of Federal Regulations and is suitable for use as described therein. CORVE8100-50 The 50% styrene version of CORVE8100, with viscosity of 100 cps and a gel time of 70 - 90 minutes. CORVE8101 Promoted version of VE8100. Gel time of 15 - 20 minutes. CORVE8101-45 The 45% styrene version of CORVE8101. CORVE8770 Our highest heat distortion temperature (300 F/149 C) Vinyl Ester with outstanding retention of physicals in high heat exposure. This resin is an excellent choice in solvent exposure and in construction of high heat exposure corrosion resistant laminates.

8 Used for UL 1316 All Fuels applications. CORVE8771 Promoted version of CORVE8770. Gel time of 15 - 20 minutes. CORVE8710 High cross-link version of CORVE8300, with excellent caustic and solvent resistance. 8 Corrosion Resistant Vinyl Ester Resins Fire Retardant Vinyl esters CORVE8400 Series Fire Retardant These fire retardant Vinyl esters are brominated counterparts of CORVE8300, and therefore also exhibit outstanding corrosion resistance. CORVE8400 This resin has an ASTM E84 flame spread of less than 25 without the use of additives such as antimony. This results in clear laminates that can be easily inspected for poorly wetted glass, air bubbles or other defects that can degrade the performance of the composite. CORVE8401 Promoted version of CORVE8400. CORVE8440 When mixed with antimony tri oxide*, the flame spread rating of this resin is less than 25 (ASTM 84 Tunnel Test).

9 At the same time, CORVE8440 retains excellent physical properties and corrosion resistance. CORVE8441 Promoted version of CORVE8440. Gel time of 15-20 minutes. CORVE8442 Pultrusion version of CORVE8440. CORVE8430 This scrubber assembly was manufactured with VE8300 Resins . Low Smoke. This low smoke-emitting fire retardant Vinyl Ester resin is designed to be used in co mbination with alumina trihydrate. In the flaming mode, a smoke density of 82 was achieved in 90 seconds with a mixture of 45% ATH and 55% resin in the laminate with 30% fiberglass reinforcement when tested according ASTM E662. 9 CORVE8461 The thixotropic version of CORVE8440 for open mold applications. CORVE8470 High cross-link version of CORVE8440. CORVE8471 Promoted version of CORVE8470. CORVE8480N Brominated novolac epoxy Vinyl Ester with a class 2 flame sp read rating. CORVE8462 Infusion version of CORVE8440 that is promoted and has a typical gel time of 50 minutes The Use of Antimony Trioxide in Fire Retardant Resins Antimony trioxide should be added immediately before using the resin and only to enough resin for an eight-hour period.

10 If the antimony is added and the resin is not used in eight hours, the gel time can increase and cause gel and cure problems. When using resin that has had antimony trioxide added over eight hours before, the gel time and cure profile should be checked to ensure it will gel and cure, as well as perform properly, in the specific application. An additional weight per percent of 12% cobalt can be added to reduce the gel time. If a further decrease in gel time is required, a maximum addition of DMA may be incorporated.
