PC-1644®

PC 1644™ Defoamer is a 40 % solution of an acrylic polymer in a petroleum solvent. It was developed to offer improved defoaming performance versus PC- 1244 in non-aqueous organic fluids. PC 1644™ Defoamer is a general purpose defoamer which offers superior foam control at low use levels, generally 10 to 20 % lower use level versus PC-1244. PC 1644™ Defoamer is silicone-free and exhibits very low odor. PC-1644 defoamer applications include usage in gear oils, specialty lubricants, and shock absorber, hydraulic, turbine or transmission oils. Typical use levels of the solutions range from 50 - 500 ppm (20 - 200 ppm active polymer). The optimum level is dependent upon the nature of the oil and it is therefore necessary to run a concentration profile for each oil. The defoamer is most typically employed at 200 - 250 ppm of solution (80 - 100 ppm active polymer).
