What’s Inside Paints and Coatings
« What influences the paint quality » In surface treatment, paints and coatings are applied to components to protect them from environmental damage, enhance their appearance, or modify surface properties. Paint ingredients form a complex system tailored to the intended …
Read more »What Are Chromates and Where Are They Used?
Chromates, which are chemical salts derived from chromic acid, play a role in two distinct surface treatment processes: Chromating, where chromic acid or its salts create a chromate layer on a material’s surface. Chromium plating, where dissolved chromates (electrolytes containing …
