Abstract
Powder composition and method for polishing stone. The present invention relates to a powder composition and to a method for polishing stone, in particular granite, said method making use of said powder composition.
Claims26
A stone polishing composition comprising:
- 10 to 40% by weight of stannic oxide particles having an average particle size (D50 micron) of 1 to 10 μm, and
- 60 to 90% by weight of a stainless steel powder having an apparent density of 4.5 to 5.0 kg/dm3 and a particle size of less than 0.5 mm, and
- 0.01 to 20% by weight of a powder wax related to the total weight of the stannic oxide particles and the stainless steel powder.
