EPON™ Resin 1183 and 1183-T-70

 

 

Product Description

EPON™ Resin 1183 is a brominated epoxy resin with a moderate bromine content. It was designed for applications requiring good sintering resistance at room temperature and moderate flammability resistance. EPON Resin 1183 can be used in solid form for blends with liquid epoxy resins or hot melt applications, or dissolved in an appropriate solvent for laminating or similar applications.

 

EPON Resin 1183 is also available as a solution in toluene at 70 weight percent solids, designated as EPON Resin 1183-T-70.

 

EPON Resin 1183 is a reaction product of bisphenol A, tetra-bromobisphenol A, and epichlorohydrin.

Processing/How to use

 

Applications

EPON Resin 1183 offers alternatives for formulators seeking replacements for tetrabromobisphenol A, octa- and decabromodiphenyl oxides, antimony trioxide, phosphorus compounds, and other flame retardant additives for a variety of applications, including coatings, laminating, and composites. EPON Resin 1183 in solid form is most appropriate for those applications that require a moderate bromine level and resistance to sintering at room temperature. EPON Resin 1183-T-70 provides the material in solution for ease of processing with solvent-based systems.

 

Processing

The effects of temperature on the typical viscosity of EPON Resin 1183 are provided by Figure 1. The physical characteristics of non-sintering solid at room temperature, low melt viscosity at elevated temperatures, good solubility in a variety of epoxy resins and solvents, and moderate bromine content make EPON Resin 1183 a good choice for a wide variety of processing techniques. In epoxy based resin systems, 10-20 weight percent bromine from EPON Resin 1183 is generally sufficient to impart the desired level of flammability resistance.

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 1183 and EPON Resin 1183-T-70 should be kept in cool, dry conditions in tightly closed containers, preferably in the original packaging. Under these conditions, the products should have a storage life of at least one year.

 

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.
