High thickness of zinc silicate cause
WebDec 5, 2001 · Zinc potential increases in the presence of these ions, while the steel or iron potential remains unchanged. This causes the steel to become anodic, and the zinc to become cathodic, thereby causing the steel to corrode in order to protect the zinc. WebIf zinc silicates are applied at too high a dry film thickness, problems can arise eg. mud cracking or low cohesive strength. An understanding of what is happening can help avoid trouble: a. Mud Cracking In some situations after the application of a zinc silicate, the film …
