United States Products Co was founded in 1917. The company's line of business includes the manufacturing of abrasive products.

United States Products Co. was founded in 1917 as a manufacturer of lapping, grinding and polishing compounds.

• Extreme accuracy of lapped surfaces (flat or spherical)
• Close parallelism of double lapped faces
• Extremely close fit between mating surfaces
• Removal of damaged surface and sub-surface layers that may degrade electrical and/or optical properties of the lapped workpiece.
Polishing is just lapping using finer abrasive products.
