T.C. 81

PRIMARY APPLICATION

T.C. 81 is added in minute amounts to the water in cooling canals and retorts of U.S. food plants (except those processing meats) to prevent water spotting. It acts to reduce the surface tension of water, thereby thinning it out. Cans or jars thus treated dry down quickly, uniformly and cleanly with no significant water spotting or dulled surfaces. Labels are easier to apply and adhere better. Faster dry down helps retard metal corrosion. In addition, T.C. 81 may be used in metal processing as a final rinse aid, after chrome plating or other operations where water spotting may be a problem. It also improves cleaning and wetting out properties of Tru-Chem phosphate materials. T.C. 81 is approved for use in meat and poultry processing plants ( as well as other food plants) by the CDA (in Canada).

NOTES ON USE

Safety and Handling Precautions

T.C. 81 is a moderately alkaline material. Direct contact causes irritation of eyes. Prolonged skin contact may cause irritation. It is harmful if swallowed. Do not get in eyes. Avoid prolonged skin contact. Wash thoroughly after handling. Do not take internally.

First Aid in Case of Contact

For eyes, flush with plenty of water for at least 15 minutes; get medical attention. For skin, flush with water. If swallowed, give several glasses of water or milk to drink. Contact a physician.

DISPOSAL

Generally, no special treatment is required at recommended use concentrations. Discharge in accordance with Federal, State and local regulations.
