1.Touch optimization: the pursuit of softness and fullness

In view of the frequent skin-to-skin contact of fabrics, the primary goal of the design of waterborne polyurethane coatings is to achieve soft touch and full form. This requires us to carefully balance the ratio of hard and soft segments in the formulation adjustment, while carefully selecting the types of both to ensure that the coating retains the necessary support without losing its fineness and comfort.

2.Heat stable: stick to high temperature

Considering the high temperature environment that fabrics may encounter during processing, transportation and use, waterborne polyurethane coatings require excellent heat stability. This means that under high temperature closed conditions, the coating can maintain its original form and function, non-adhesion, non-deformation, to ensure product quality.

3.Strong adhesion: tight combination of coating and substrate

As a functional coating and adhesive, the adhesion between the waterborne polyurethane coating and the substrate fabric is very important. Only by ensuring that the coating can be firmly attached to the substrate can it give full play to its various performance advantages.

4.Solvent resistance: The ability to resist erosion

In the face of potential threats from solvents such as daily washing and alcohol, waterborne polyurethane coatings need to have excellent solvent resistance. Through the use of advanced technical means, such as sealing hydrophilic groups, the introduction of curing agent crosslinking, improve the water resistance and solvent resistance of the coating to ensure that the coating remains stable in complex environments.

5.Color persistence: The performance of color fixation

When the waterborne polyurethane coating is combined with the color paste to give rich color to the fabric, its color fixing performance becomes an important index to measure the coating quality. The high-quality coating ensures that the color is firmly locked to the fabric, making the fabric colorful and long-lasting.

6.Waterproof and moisture-permeable: dual function of balance

Although the coating treatment has a certain impact on the moisture and air permeability of the fabric, the water-based polyurethane coating can improve the moisture permeability of the fabric while maintaining the waterproof performance, and achieve a good balance between waterproof and air permeability by introducing innovative technologies such as hydrophilic groups.

7.Superhydrophobic exploration: Implications for nature

Inspired by the superhydrophobic phenomenon of lotus leaves, waterborne polyurethane coatings are gradually moving into the field of superhydrophobic. By imitating the special structure of the surface of the lotus leaf, a coating with super hydrophobic properties has been developed to bring unprecedented protection to the fabric.

8.Efficient preparation: Advantages of high solid content and low viscosity coatings

The development of water based polyurethane coating with high solid content and low viscosity not only improves the film forming speed and drying efficiency, but also conforms to the trend of energy saving and emission reduction. Its excellent performance characteristics provide strong support for the application of waterborne polyurethane coatings in a wider range of fields.
