Binders

In surface technology, binders play a central role in the production of coatings and paints. Binders are substances that bind the components of a coating together and allow them to adhere to the surface. They contribute significantly to the durability, adhesion, flexibility and other important properties of the coating.

There are different types of binders that can be selected depending on the area of application and the desired properties. Some of the most common binders used in surface technology are

1. polymer binders: polymer binders are commonly used in coatings and paints to create a flexible, tough and weather resistant surface. These binders can be water-based (e.g. acrylic or latex polymers) or solvent-based (e.g. alkyd resins) and offer a wide range of application possibilities.

2. epoxy resins: Epoxy resins are used for coatings that require high chemical resistance and mechanical strength. They cure through chemical reactions and form a hard, durable surface.

3. polyurethanes: Polyurethane binders are used in coatings that require high abrasion resistance, weather resistance and chemical resistance. They can be available in the form of two-component systems or as one-component systems that cure through atmospheric moisture.

4. alkyd resins: Alkyd resins are often used in oil paints and varnishes and offer good adhesion to various substrates as well as a fast drying time.

The selection of the right binder depends on various factors, including the type of substrate, the environmental conditions, the desired properties of the coating and the application requirements. By selecting the appropriate binder, manufacturers can produce high-quality coatings that meet the requirements of their specific application.
