Polyurethane dispersions

Polyurethane dispersions are a type of polymer dispersion made from polyurethanes and used in various applications in the coatings industry. These dispersions consist of finely dispersed polyurethane particles suspended in an aqueous medium and can have different properties depending on their composition and manufacturing process.

Polyurethane dispersions offer a variety of benefits in the coatings industry. These include:

1. flexibility: polyurethane dispersions are known for their high flexibility and elasticity, which makes them particularly suitable for coatings on flexible substrates such as textiles, leather or plastics.

2. abrasion resistance: Polyurethane-based coatings are often very abrasion-resistant and resistant to mechanical stress, which makes them attractive for heavy-duty applications such as floor coatings or varnishing of furniture and machinery.

3. chemical resistance: Polyurethane coatings usually offer good resistance to chemicals, oils and solvents, making them suitable for applications in aggressive environments.

4. weather resistance: Polyurethane dispersions can also have good weather resistance and are therefore suitable for use outdoors or in applications with extreme weathering.

5. adhesion: The dispersions can provide excellent adhesion to various surfaces due to their chemical structure and ability to bond well to a variety of substrates.

Polyurethane dispersions are used in a variety of applications, including paints and coatings for furniture, flooring, automotive parts, textiles, leather goods, paper and packaging. Their versatile properties make them a popular choice for manufacturers looking for robust and hard-wearing coatings that can meet a wide range of requirements.
