High Flammability Resistance, Solid Epoxy Resin With a Relatively Low Softening Point
EPIKOTE 1163, a highly brominated epoxy resin, is designed for applications requiring a high degree of flammability resistance. It is a solid epoxy resin with a relatively low softening point and will sinter or block at room temperature. EPIKOTE 1163 is commonly handled in solvent for laminating applications, as a hot melt for casting and molding compound applications, or as a blend with liquid epoxy resins for miscellaneous casting, potting, encapsulation and floor topping uses that require processing at ambient or slightly elevated temperatures. It is also commercially available as a solution in toluene at 60 weight percent solids, designated as EPIKOTE Resin 1163-T-60. EPIKOTE Resin 1163 is a reaction product of tetrabromobisphenol A and epichlorohydrin.
EPIKOTE 1163 Applications
EPIKOTE Resin 1163 offers an alternative 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. These applications include but are not limited to laminating, powder coating, or composite applications, to manufacture flame retardant vinyl esters, or as a flame retardant additive for thermoplastic polymers. EPIKOTE Resin 1163-T-60 is widely used as a reactive flame retardant component for phenolic resins used for the manufacture of printed circuit boards conforming to NEMA FR-1 and FR-2 specifications. EPIKOTE Resin 1163-T-60 can also be used for high performance circuit board applications including the epoxy-based FR-4 and FR-5 grades.
EPIKOTE 1163 Processing
EPIKOTE Resin 1163 is advantaged by its relatively low melt viscosity (see Figure 1), high bromine content, very good compatibility with epoxy resins, and efficient flame retardant performance. In epoxy based resin systems, 10-20 weight percent bromine is generally sufficient to impart the desired level of flammability resistance. Blending EPIKOTE Resin 1163 with bisphenol A-based epoxy resins and/or reactive diluents to reduce the bromine content of the total system is a common practice and such modifications often result in a liquid product. A composition’s resistance to flame spread can also be enhanced by adding a synergistic flame retardant such as antimony trioxide or an intumescing agent such as ammonium polyphosphate.
