By continually tackling technical challenges in our application laboratories, we are able to translate real world requirements into high quality, production-oriented materials. The EPON™ and EPI-REZ™ families of resins were developed to provide superior overall performance in a variety of end-use applications. These products enable manufacturers to achieve nearly any desired performance level, while optimizing processability and strength retention at elevated temperatures. At A Glance EPON™ – Liquid Epoxy Resins and Blends 6–7 This segment of our product line represents the most widely used products in a number of industries. The most commonly used EPON Resin/V. C. HELOXY™ Modifier blends are available in several types and viscosity grades. EPON – Epoxy Resin Solutions 8–10 These products are higher molecular weight standard or modified epoxies which are dissolved in solvent to allow easier handling and formulation because of lower viscosity. EPON – Solid and Powder Grade Resins 10 –11 These epoxy resins are in the molecular weight range most suitable for use in epoxy solutions, powder coating, composite and electronic applications. These products have a good balance of properties, including appropriate epoxy functionality for proper curing, good physical stability (sintering resistance), and good melt flow (low melt viscosity). EPON – Epoxy Novolac Resins 12 These products are specifically designed to provide increased levels of thermal stability and chemical resistance, and are used in composites, structural adhesives, electronics / electrical and coating applications. EPON – Epoxy Polyacrylates 13 These are very low viscosity resins possessing excellent wetting characteristics and rapid reaction rates with amine curatives over a broad temperature range. EPON – Elastomer Modified Epoxy Resins 13 These products offer improved adhesive properties, thermal shock resistance and toughness, with good fatigue resistant properties. EPONEX™ – Cycloaliphatic Resin 13 This segment offers a low viscosity liquid epoxy based on hydrogenated Bisphenol A for applications requiring UV resistance. EPON and EPONOL™ – Electrical Laminating Resins 14 These products can be used to obtain fire retardance in a base epoxy resin formulation. The ultra-high molecular weight resin can be used to improve flexibility and modify the flow properties of the system. EPON and EPIKOTE™ – Epoxy Resins for Composites 14 Epoxy resins that provide the property retention, toughness and corrosion protection required in composite applications. ■ EPI-REZ™ – Epoxy Waterborne Resins 15 These non-ionic aqueous dispersions of our epoxy resins provide benefits such as lower VOC, extended pot life, high crosslink density, high temperature performance, very good chemical resistance, B-stage capability, low color, and complete water-reducibility. Many of the Hexion EPIKURE™ Curing Agents can be used with these epoxy dispersions. In addition, since dicyandiamide is water soluble, it may be used to provide extended pot life formulations. 2 The Formulator’s Choice All of our products are manufactured to high standards of quality and have very specific property ranges. To help you assess the many production and performance advantages of Hexion’s complete line of resins, we’ve summarized typical properties and resin characteristics in this product bulletin. The data in this bulletin is intended to give only basic product information for quick reference—individual product technical data sheets with additional information are available for most of the products listed in the following pages. For additional information about these products, or to contact us, visit the Epoxy, Curing Agents and Modifiers section of the Hexion website at www.hexion.com/epoxy Resin Solution Coding System Epoxy resins employ a simple three-part coding system for designating the composition of resin solutions. The coding system consists of a number indicating the epoxy resin used in the particular solution, followed by one or more letters that describe the solvent or combination of solvents used to make up the solution. The last two numbers indicate the percent solids (by weight) of the composition. For example: EPON™ Resin 1001-H-75 In this example, the base resin used to make this solution is the EPON Resin 1001F type. The solvent used is Propylene Glycol Monomethyl Ether (PM), as shown in the next table, and the solids content is 75 percent by weight. The coding system that is used to designate the solvents in resin solutions is shown on the next table (pg 5): 3 Solvent Coding System Letter Solvent Name Abbr Non HAPS 1 VOC Exempt 2 Code A Acetone Yes Yes B Methyl Ethyl Ketone MEK Yes C Methyl Isobutyl Ketone MIBK D Diacetone Alcohol DAA Yes E Isopropyl Alcohol IPA Yes F n-Butyl Alcohol (Converting to Code "N") NBA Yes G n-Butyl Acetate NBAC Yes H Propylene Glycol Monomethyl Ether PGMME / PM Yes I iso-Butyl Alcohol Yes J Ethyl 3-Ethoxy Propionate EEP K t-Butyl Acetate TBAC Yes Yes L Propylene Glycol Mono n-Butyl Ether PGMnBE / PnB Yes M Ethylene Glycol Monobutyl Ether EGMBE / EB Yes N n-Butyl Alcohol NBA Yes O Methyl n-Amyl Ketone MNAK Yes P n-Propyl Alcohol NPA Yes Q Propylene Glycol Monomethyl Ether Acetate PGMMEA / PMA Yes R Dimethyl Formamide DMF S Cyclohexanone Yes T Toluene U Aromatic 100 A 100 < 5% HAPS V Dipropylene Glycol Monomethyl Ether DPGME Yes W Water Yes Yes X Xylene Y Ethylene Glycol Monopropyl Ether EGMPE / EP 1 HAP is the acronym for hazardous air pollutant as defined by the U.S. Clean Air Act Amendments of 1990. 2 VOC is the acronym for Volatile Organic Compound as defined by the U.S. 40 CFRS1.100 (s). VOC exempt solvents are classified as such by the U.S. EPA, local state and regional air quality districts. 4 Table 1: Typical Properties of EPON™ Unmodified Liquid Epoxy Resins Product Chemical Type Viscosity Weight per Color1 Density Comments at 25 °C (P) Epoxide (max) (lb/gal) EPON 825 DGEBPA 50 – 65 175 –180 250 9.7 Ultra high purity, low viscosity liquid epoxy used for high solids coatings and specialty composites.
