use of replaced: phenols in mixture with 3,5,5, - trimethyl 3 aminomethylcyclohexylamin and / or menthandiamin as vernetzungsmittel for epoxidverbindungen

摘要

Substd. phenols of formula: where R1 = H, CH3, C2H5, C3H7, C4H9 or R2 = NH.CH2 CH2.NH2, NH.CH2 CH2.NH2, NH.CH2.C(CH3)2.CH2.CH(CH3)NH2-CH2-CH2 NH.CH2.CH(CH3).CH2.C(CH3)2.CH2CH2.NH2, R3 = H, CH3, (CH3)3.C, HO or HO B, in which B = CH2, C(CH3)2 or SO2, n = 1-3, and m 1-3, mixed with 3,5,5-trimethyl-3-aminomethyl cyclohexylamine and/or menthane diamine yield cured epoxy resins which are relatively free from yellowing, and have longer pot life.
