Car windshield

January 2018 – A large automotive glass producer completely eliminated their water spotting problem by using Engineered Coolants products. In addition, they also saw numerous other benefits. Using both EC coolant and EC’s Score cutting fluid, they saw their edge quality improve dramatically (see images in PDF file), surface tension improved to 64 dynes, rejected glass due to pin holes decreased by 64%, rinse water temp was reduced from 140 F to 100 F, the frequency between wheel dressings doubled (20 to 40 cycles), production increased (360 more pieces per day on 3 lines), grinding wheel life doubled (up to 7 redressings now), and much more.
