A Word on Compounds from U.S. Products Co.

Our paste type compounds have an oil-soap base or vehicle that holds the abrasive in suspension and allows lapped parts to be readily cleaned with the usual solvents.

These compounds are sensitive to temperature and should be stored in a cool place. They should not be placed on a radiator, exposed to direct sunlight, or stored in a place with higher than normal temperatures.

Age improves the lapping quality of the base or vehicle. Time seems to change the chemical structure of the base and a film of old compound on a lapping plate is an improvement over new or fresh compound. For special or unusual lapping operations we age our compounds. Some customers purchase an excess amount and store it for a number of months prior to its use. Another customer actually heats or cooks our compound before using it while another stores the compound in a household refrigerator and will use it only when cold. All these methods seem to work well for these specific customers and their unusual lapping operations.

Many grades of compounds are formulated that are not shown on our list. These have been developed by us to meet specific conditions or requirements. Special lapping operations sometimes require special compounds combined with special lapping techniques. Many polishing operations can be best performed using fine abrasives and "Pellon Pads." These cloth or composition pads have an adhesive back and can be placed on hand or machine lapping plates.

After some years of research and development we have available both Diamond and Borazon™ CBN lapping pastes and slurries. The many rules of thumb that apply to standard abrasive compounds also apply to these super abrasive compounds in the lapping process. However, there are differences and we are now publishing technical data that specifically outlines the "how to" of lapping and polishing with super-abrasives--Diamond and Borazon™ CBN.

We welcome the opportunity to share with you our knowledge and experience gained in 75 years of producing lapping or grinding compounds. Our compounds will not solve every lapping problem, but we firmly believe that they will solve the majority of problems encountered in today's lapping operations.

Our standard size containers are available for your immediate use, or we will package our compounds in your selected containers and allow your company to do its own special labeling.

We have many compounds for all kinds of valves, taper or plug, safety relief, pressure, control, etc. We can supply compounds for lapping gears of all types, sizes and metals, from the large industrial and turbine gears to the tiny gears in computing devices. We can formulate for your shop, special compounds containing specified grit sizes to satisfy your individual shop conditions. 75 years of studying lapping problems and the formulation of many special compounds has given us a wide experience for solving all kinds of unusual lapping problems.
