Abstract of the Disclosure The invention relates to adducts of tetra- substituted titanates and di-substituted hydrogen phosphites; the use of such adducts for treating particulate fillers, including pigments; the compositions of fillers and the aforesaid adducts with epoxy resins and other casting resins; the reaction product of said adducts with aromatic polyamines; the use of said reaction products for curing epoxide and urethane resins; and compositions of certain of the adducts and casting resins. The titanate-phosphite adducts serve to reduce the viscosity of filled epoxy resins, thereby permitting higher filler loading, to enhance the tinctorial power of pigments, and to render casting resins water-extendible. The titanate-phosphite adducts are the reaction products of one mole of a compound having the formula (RO)4Ti and two moles of di-substituted hydrogen phosphite, (R'O)2P(O)H, where R and R' are monovalent alkyl, alkenyl, aryl, aralkyl or alkaryl. Both R and R' may be alkoxy, aroxy, bromo or chloro-substituted derivatives of the aforesaid groups. R may have form 1 to 18 carbon atoms, preferably 3 to 12, except where the titanates are used for water-extension, where R is preferably 6 to 12. R' may be from 3 to 18, preferably from 6 to 14.
