EPON™ Resin 863

 

 

Product Description

EPON Resin 863 is a low viscosity, undiluted, difunctional epoxy resin produced from bisphenol-F (BPF) and epichlorohydrin and was specially developed to provide good resistance to crystallization.  When cross-linked or hardened with appropriate curing agents, very good mechanical, adhesive, chemical and electrical properties are obtained.

 

Application Areas/Suggested Uses

  • Solventless or high solids/low VOC maintenance and marine coatings
  • Chemical resistant tank linings, floorings, and grouts
  • Fiber reinforced pipes, tanks, and composites
  • Tooling, casting, and molding compounds
  • Construction, electrical, and aerospace adhesives
 

 

Benefits

  • Low viscosity
  • Low color
  • Improved crystallization resistance relative to EPON Resin 862 and diluted BPA epoxy resins
  • Can be blended with EPON Resin 828 and other epoxy resins
  • Reacts with a full range of epoxy curatives
  • Good balance of mechanical, adhesive, and electrical properties
  • Good chemical resistance

General Information

Difunctional BPF epoxy resins, such as EPON Resin 862 and EPON Resin 863, are generally easier to process than their BPA epoxy counterparts largely due to the lower resin viscosity (summarized in Table 1).  The lower resin viscosity permits the use of higher filler levels and makes it easier to incorporate fillers into formulations.  For solvent-based systems, the lower resin viscosity allows for higher solids levels and lower VOC for the same formulated viscosity.  BPF epoxy resins can also be blended with EPON Resin 828 and other epoxy resins or HELOXY modifiers to lower the viscosity for ease of formulating and improved processing.

EPON Resin 863 offers improved crystallization resistance relative to many BPF epoxy resins, including EPON Resin 862.  When stored for 6 months at 40°F, EPON Resin 863 remains clear and free of haze, while EPON Resin 862 crystallizes.  EPON Resin 863 is also more crystallization resistant than diluted BPA-epoxy resins.  The improved crystallization resistance of EPON Resin 863 relative to other liquid epoxy resins is demonstrated by Figure 1 for highly accelerated test conditions. 

 

When appropriately cured, BPF epoxy resins provide comparable mechanical, chemical, and electrical properties to those of BPA epoxy-based systems, and significantly improved properties to those of diluted BPA epoxy resin systems.  The handling and cured state properties for EPON Resin 863 formulated with a range of typical curing agents are listed in Table 2.

Safety, Storage & Handling

Please refer to the MSDS for the most current Safety and Handling information.

 

Please refer to the Hexion web site for Shelf Life and recommended Storage information.

 

EPON Resin 863 should be stored in tightly sealed containers of metal, glass, or polyolefin plastic at normal room temperatures.  If EPON Resin 863 develops haziness or crystallizes during storage, it can be restored to its original condition by gently warming the container and its contents to approximately 140-150°F until all visual evidence of crystallization is gone.  Upon cooling to normal ambient temperature conditions, the product will regain its original liquid state physical properties.  This process can be repeated as necessary.

 

Exposure to these materials should be minimized and avoided, if feasible, through the observance of proper precautions, use of appropriate engineering controls and proper personal protective clothing and equipment, and adherence to proper handling procedures. None of these materials should be used, stored, or transported until the handling precautions and recommendations as stated in the Material Safety Data Sheet (MSDS) for these and all other products being used are understood by all persons who will work with them. Questions and requests for information on Hexion Inc. ("Hexion") products should be directed to your Hexion sales representative, or the nearest Hexion sales office. Information and MSDSs on non-Hexion products should be obtained from the respective manufacturer.
