Grit binders are a key class of additives used in the application of ceramic grits and microbeads, whether applied by wet or dry methods. Their main purpose is to ensure optimal adhesion of the particles to the ceramic substrate, improving the stability of the coating and enhancing the final aesthetic quality of the surface.

These additives play a crucial role throughout the production process by addressing several critical factors. They promote strong particle adhesion, securing the grits firmly to the ceramic surface and reducing the risk of detachment during handling and firing. They also help achieve a smooth and even distribution of the solid components, preventing build-ups or bare spots and ensuring a consistent, uniform finish. Thanks to their versatility, they are effective with a wide range of application techniques: airless, disc, vela, bell.

In some cases, grit binders developed by Zschimmer & Schwarz can also enhance the mechanical strength of the unfired product, improving the cohesion of the coating and making it more resistant to the stress and mechanical demands of application equipment during production. This results in a more reliable process and a higher-quality finished product.
