  1. Gabriel Performance Products Cycloaliphatic Epoxy Resins GPE Series Product Technology, Curatives & Applications

  2. Cycloaliphatic Epoxy Resins (CER) • Outline • Technology • Features/Benefits - Value • Products • Activators/Hardeners • Markets/Applications GPE Series

  3. Cycloaliphatic Epoxy Resins (CER) Technology

  4. CER Technology • CERs - Different from Standard Bisphenol-A Epoxy Resins like DER 331, EPON 828 • Standard Epoxy resins made from Epichlorohydrin and Bisphenol-A • CERs are made by oxidation of Cyclo Olefins with Peracetic Acid • Different from other cycloaliphatic epoxy resins like Glycidyl Esters of Pthalic Acids (Huntsman CY 184) and Hydrogenated Bis A Epoxy Resins (CVC Epalloy 5000 and HexionEpon 1110)

  5. Technology Standard Epoxy Resin : • Epichlorohydrin + Bisphenol-A  Std. Epoxy Resin • (DER 331, EPON 828) Epichlorohydrin Bisphenol-A

  6. Technology Cycloaliphatic Epoxy Resin : • Cyclo Olefin + Peracetic Acid  GPE-221 GPE-221 Cyclo Olefin Peracetic Acid

  7. Cycloaliphatic Epoxy Resins (CER) Features/Benefits - Value Proposition

  8. Feature/Benefits - Value • Aliphatic Backbone – Excellent UV Stability • Saturated Cyclic Ring – Good Weatherability and Excellent Electrical Properties • High Epoxide Content  High Crosslink Density  High Tg and Heat Distortion Temp. (HDT) • No Epichlorohydrin  No Hydrolysable Chorine  Low Dielectric Constant  Excellent Arc-Track Resistance

  9. Feature/Benefits - Value • Short Chain – Low Viscosity  350cp of GPE-221 vs. 13000 cp Std Epoxy Resin  Easy to handle and enable VOC Free or Low VOC Formulations • When combined with Polyols, result in Good Combination of Toughness and Heat-Distortion Temperature Properties • No Epichlorohydrin  Low Potential for Skin Sensitization • Offer latitude to formulate 1K or 2K Products

  10. Cycloaliphatic Epoxy Resins (CER) GPE Products

  11. GPE Series - Products • GPE-221 : Standard, General Purpose Use Cycloaliphatic Epoxy Resin  Equivalent to ERL-4221 (Cyracure UVR-6110) • GPE-226 : Distilled, Low Ionic Content and Low Viscosity Cycloaliphatic Epoxy Resin  Equivalent to ERL-4221D (Cyracure UVR-6105) • GPE-228 : Flexible Cycloaliphatic Epoxy Resin  Equivalent to ERL-4299 (Cyracure UVR-6128) • ERL & UVR from Dow Chemical - Discontd.

  12. GPE Series - Properties

  13. Cycloaliphatic Epoxy Resins (CER) Activators/Hardeners

  14. Activators/Hardeners • Anhydrides • Polyacids • UV Cationic Cure Catalysts • Not ‘Amines’ or ‘Polyamides’

  15. Activators/Hardeners • Anhydrides • 2K Thermal Cure OR Heat Cure • Requires Heat to Cure • HHPA (HexaHydroPthalicAnhydide), MTHPA, NMA • Typical Cure Cycle – 1 HR @ 100 -120 oC + 4 - 6 HR @ 160 -180 oC • Cure Cycles vary with different Anhydrides

  16. Activators/Hardeners • Anhydride Cured CERs • Excellent High Temperature Performance • Tg : 150 – 200oC • High Mechanical Properties - Flexural Strength, Compressive Strength • Excellent Dielectric Properties • Superior Arc, Corona and Tracking Resistance • Eg: Fiber Reinforced Composites

  17. Activators/Hardeners • Polyacids • 2K Ambient Cure • Acid Functional Polyesters, Carboxylic Acids, Pthalic Acids • Slow Reaction Rates • Takes several days to cure • Less Common in Use

  18. Activators/Hardeners • UV Cationic Cure Catalysts • Cationic Photoinitiators • “Aryl Sulfonium” and “Aryl Iodonium” Salts • Activated by UV Light  Generate a Super Acid • Super Acid catalyzes epoxy polymerization • Rapid Cure Rates, in some cases Instant

  19. Activators/Hardeners • UV Cationic Cure Catalysts • Alternate technology to Free Radical Polymerization of Acrylates • Low Shrinkage – up to 5%, compared to Acrylate Shrinkage of 10- 15% • Excellent Adhesion • Low Viscosity  Low or No VOCs • Low Capital and Operating Costs • Excellent Hardness and Flexibility

  20. Cycloaliphatic Epoxy Resins (CER) Markets/Applications

  21. Value to the Market • CERs have Excellent UV and Weatherability, Low Viscosity, High Temperature Performance, Excellent Electrical Properties and other…….But • Complex Mfg Process • High Product Costs • $ 6 - 10/lb vs $1 – 2/lb of Standard Epoxy Resin • Used in High Performance Requirement Markets/Applications

  22. Markets/Applications 2K ANHYDRIDE CURE • Fiber Reinforced Composites • Low Viscosity – Good Fiber Wet-out • Filament Winding, Pultrusion, Resin Transfer Molding (RTM) • Tg in the range of 200oC – High Temperature Performance • Eg: Aerial Booms, Antennas, Composites for Electrical and Electronic Applications

  23. Markets/Applications • Electric Insulators • Ceramic or Porcelain Replacements • Bushings, Electric Insulators, Switch Gear Parts in transmission and distribution of electric power • Excellent UV Resistance and Carbon Tracking • Lighter Weight & Greater Impact Resistance • Complex Shapes, Reduced Maintenance 2K ANHYDRIDE CURE

  24. Markets/Applications 2K ANHYDRIDE CURE • Encapsulants & Potting Compounds • Transformers, Electric Coils • Low Dielectric Loss • High Electrical Resistivity • Low Viscosity – Good Penetration • Excellent UV Resistance – LEDs and Optoelectronics • Excellent Thermal Shock Resistance with Polyols
