Applications of Dispex CX 4225

Dispex CX 4225 is a low molecular weight polymer with highly hydrophilic properties. 

Dispex CX 4225 is a coating resin with outstanding adhesion properties on polar substrates. 

Typical applications of Dispex CX 4225 include glass coatings, coatings on ceramic surfaces, and glass-fiber coatings (e.g., for glass-fiber reinforced polyester systems). 

The absence of inorganic salts in Dispex CX 4225 is another property of high importance for applications requiring the glass-fiber system’s sustainable mechanical strength. 

Typical examples of such demanding applications are parts for yachts and wind blades. 

Dispex CX 4225 is compatible with a variety of other water-based resins. 

It is particularly compatible with most acrylics, styrene acrylics, polyesters, and rosin-modified maleic resins.

Dispex CX 4225 is a chemical raw material that can be used as a dispersant in various applications. 

Dispex CX 4225 is a highly effective anionic polycarboxylate used to stabilize suspensions and improve the dispersibility of solids in liquids.

Dispex CX 4225 is often used in the paint and varnish industry to improve pigment dispersion and increase color stability. 

It enables even distribution of pigments in the color matrix and prevents them from agglomerating. 

This results in improved color intensity, higher opacity, and better resistance to flocculation.

In addition, Dispex CX 4225 is used in construction chemistry, especially in the production of cement and concrete admixtures. 

It improves concrete’s flowability, reduces the amount of water required, and increases the strength and durability of the final product.

Recommended dosage 

Dispex CX 4225 may be used as the only or as the main binder in the formulation. 

As any component present in a formulation can significantly impact its overall properties, compatibility and dosage level should always be checked in the actual formulation.

Storage 

Dispex CX 4225 should always be stored in tightly closed containers. 

Store in a cool place.
