ABSTRACT:
A process for preparing a metal-coated hollow microsphere comprising the combination of steps of: (a) vigorously admixing a major quantity of hollow cenospheres/microspheres with a thermo-setting binder adhesive until the cenospheres are wet-out; (b) slowly adding metal flakes to the thus wet-out cenospheres of step (a) until the wet-out cenospheres are fully coated with the metal flakes; (c) binding the metal flakes to the said wet-out cenospheres by slowly increasing the temperature of the metal coated wet-out cenospheres from step (b), the temperature being raised up to about 350.degree. F.; and (d) the metal-coated cenospheres of step (c) are intermittently admixed in the absence of any further heating until dry. The dry product is ready for packaging.
