Assignee: 3M INNOVATIVE PROPERTIES COMPANY
Field: Surface technology, coating (Chemistry)
Classification: CPC B  C | IPC B  C

Claim 13:
14. A surface coating composition comprising:
a binder precursor comprising a urethane resin composition;
urethane resin beads having an average particle diameter of 3 μm to 30 μm;
hard particles having an average particle diameter of 5 μm to 45 μm, wherein a ratio of the average particle diameter of the hard particles to the average particle diameter of the urethane resin beads is not less than 1.2, wherein the hard particles have a spherical shape; and
nanosilica particles,
wherein the surface coating composition comprises from 30 parts by mass to 500 parts by mass of the hard particles based on 100 parts by mass of the binder precursor, wherein the surface coating composition comprises from 30 parts by mass to 500 parts by mass of the nanosilica particles based on 100 parts by mass of the binder precursor.
