Abstract of the Disclosure A thixotropic polyurethane resin composition which comprises; (1) A polyurethane prepolymer in the form of liquid or solution, (2) Colloidal silica, and (3) A polysiloxane-polyoxyalkylene polymer of the general formula Image (I) [wherein R1, R2 , R3 and R4 are the same or different and each is a methyl or phenyl group; m is an integer of 0 to 70; one of X and Z is a polyoxyalkylene containing a group represented by the formula: -(CH2)n - O{(C3H6O)a(C2H4O)b}- R5 (i) (wherein n is an integer of 1 to 4; a is an integer of 0 to 50; b is an integer of 10 to 100; R5 is hydrogen, an alkyl group of 1 to 8 carbon atoms or an alkylcarbonyl group of 1 to 18 carbon atoms, and when a is an integer of not less than 1, the C3H6O and C2H4O groups may be linked to each other in arbitrary orders), and the other is methyl, phenyl or a polyoxyalkylene containing group represented by the formula (i); y1 and y2 are the same or different, and each is methyl, phenyl or a polyoxyalkylene containing group represented by the formula (i) described hereinbefore, whereby in the case of m being not less than 2, y1 and y2 may vary per repeating unit within the scope as defined hereinbefore]. shows excellent thixotropic property even by the addition of solvents, plasticizers, fillers, pigments and other additives used in the urethane industry and can restore its thixotropy quickly even after a high shear stress is improved on the composition.
