PURPOSE: To obtain low initial mixing torque and low total mixing energy at a time of mixing even if a filler of a high filling level is used in a compsn. by applying surface treatment to a filler raw material before the mixing with a binder and treating the filler raw material with a specific silane.
CONSTITUTION: An injection moldable compsn. suitable for forming a ceramic or metal substrate comprises a combination of an org. or metal filler present in an amt. of at least about 63-92 vol.%, a binding org. matrix resin and an organosilane treatment reactant represented by formula I (wherein at least one of X1, X2, X3 or X4 is a 10-35C unfunctionalized alkyl or alkenyl group and at least one of X1, X2, X3 or X4 is an alkoxy group or halide) and the compsn. shows low initial mixing torque at a time of mechanical stirring.
