Abstract
Various surfaces are polished by buffing with compositions comprising a foamed polymeric material and a finely divided abrasive material. The abrasive material has a particle size number and a valley abrasion number the product of which falls within a predetermined range sufficient to provide good polishing upon buffing. Such compositions can be fashioned into articles of manufacture which are capable of buffing various surfaces.
Claims4
A foamed polishing composition which comprises:
- (a) a foamed polymer;
- and having distributed throughout
- (b) a particulate abrasive compound, said compound having a particle size (in micrometers) and a valley abrasion number the product of which yields a number which falls in the range between 300 and 1650.
