This 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).sub.4 Ti and two moles of di-substituted hydrogen phosphite, (R'O).sub.2 P(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 from 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.
A curing composition comprising an admixture of one mole of an aromatic amine with an adduct of a tetra-substituted titanate and a di-substituted hydrogen phosphite.
A polymeric composition which comprises an admixture of an epoxy resin or a urethane resin with a curing system comprising an admixture of (A) an aromatic amine curing agent and (B) an adduct of one mole of a tetra-substituted titanate and two moles of a di-substituted hydrogen phosphite.
A method of curing an epoxy of a polyurethane resin which comprises the improvement of carrying out the polymerization in the presence of a curing system comprising (A) an aromatic amine curing agent and (B) an adduct of one mole of a tetra-substituted titanate and two moles of a di-substituted hydrogen phosphite.
A water-extended resin composition with comprises a resin for coating or casting, an organic titanate compound which is an adduct of one mole of a tetrasubstituted titanate and two moles of a dialkyl hydrogen phosphite, and from 10 to 100%, based on the weight of resin, of water.
A method of water-extending a resin composition useful for coating or casting which comprises adding to such resin from 0.1 to 5 weight percent based on resin of an organic titanate compound which is an adduct of one mole of a tetra-substituted titanate and two moles of a dialkyl hydrogen phosphite.
A resin composition which comprises a coating or casting resin containing an organo-titanate compound which is an adduct of one mole of a tetra-substituted titanate having the formula (RO).sub.4 Ti and two moles of a di-substituted hydrogen phosphite having the formula (R'O).sub.2 P(O)H wherein R and R' are monovalent alkyl, alkenyl, aryl, aralkyl, alkaryl, alkoxy or aryloxy groups and wherein R has from 1 to 18 carbon atoms and R' from 3 to 18 carbon atoms.
