Binder in floor coatings

What is a binder and when is it used?

A binder is essential for floor coatings in many respects and the quality decides on appearance and functionality.

When it comes to floor coatings, not only functionality is important.

The color of the stones or the granulate must not be influenced. The binding agent must not turn yellow, even after long exposure to the sun.

What is a binder?

A binder is a material that binds solid or liquid substances together and combines them into a whole. Binders are used in many areas, e.g. in food, cosmetics, cleaning agents, paints, plaster and cement mortar. The best-known thickening agents are pectins,   locust bean gum, carrageenan, cellulose ether, polyvinyl alcohol and silicates. Glues or adhesives are used to connect some workpieces. But gluing does not connect the fabrics to form a whole and can be easily separated again.

Which task does a binder have?

In the field of floor coatings, the functionality of the binder is very important. A high adhesion value must be achieved with the first layer between the substrate and the flooring system. The subsequent layers adhere firmly to the substrate. This is the only way for the floor coating to fulfill its functional properties, such as conductive, chemical-resistant, liquid-tight or anti-slip  resitance over a very long period of time.

What is the difference between organic and mineral binders?

The mineral thickeners consist of natural minerals from the earth, such as lime, gypsum, cement or anhydrite. Organic thickeners include bitumen, tar and synthetic resins. In the case of organic substances, processes such as heating, melting or dissolving make the binders functional in liquids.
