LITE 513DF – NEW HIGH STRENGTH DILUENT
GOOD DIELECTRIC PROPERTIES
LITE 513DF provides good insulation performance as indicated by its dielectric properties when tested according to IEC 62631 and IEC 60243 standards. In a formulation with Epon 828 at use level of 20% to the resin, cured with MTHPA (Methyl Tetrahydrophthalic Anhydride) and catalyzed by BDMA (Benzyl Dimethyl Amine), LITE 513DF showed excellent results with higher volume resistivity and dielectric strength, and lower loss factor and dielectric constant than competitive 1,4 butanediol diglycidyl ether. Similarly, LITE 513DF outperformed the petroleum-based difunctional diluent when both diluted epoxy systems were exposed to elevated temperatures or a salt solution. The combined properties of LITE 513DF make it a good epoxy diluent and modifier for electrical potting, casting, and encapsulations (impregnating resin).
