<p>1,229,017. Triglycidyl isocyanurate. HENKEL & CIE G.m.b.H. 30 Aug., 1968 [20 Oct., 1967], No. 41502/68. Heading C3B. A mixture useful in moulding comprises: (I) crystalline triglycidyl isocyanurate (T.G.I.), having an epoxide oxygen content of at least 14% by wt., and (II) a reaction product obtained by reacting an excess of amine with T.G.I., i.e. in such proportions that only 5-30% of the epoxide groups required for complete reaction are present. The amine may be an aromatic amine containing more than one amino group, e.g. 4,4<SP>1</SP> - diaminodiphenylsulphone. An accelerator, e.g. dicyandiamide may also be present. Conventional fillers, lubricants, stabilizers, dyestuffs, pigments and plasticizers may be present. The mixture may be used in conj unction with other epoxy resins. The reaction product (II) may be prepared by heating the amine with T.G.I. at 80-150‹ C. for 1 to 5 hours.</p> |
