Crosslinking agent for polyurethane coating

Crosslinking agent for polyurethane coating

Polyurethane coatings can be divided into the two-component polyurethane coatings, single component waterborne polyurethane coatings, uv-curable waterborne polyurethane coatings, room temperature curing waterborne polyurethane coatings, the third generation of water-borne polyurethane coatings (PUA), environmental protection, low aromatic polyurethane coating, etc.

Water-based polyurethane coating is based on water-based polyurethane, and water is dispersed medium. In recent years, the demand of water-based exterior wall coating and water-based wood paint, ink, and light oil is the most urgent, the development speed is very fast! In addition, water-based polyurethane coating can be used in many fields such as plastic coating, wood coating, metal coating, fabric coating, it is the main development direction of polyurethane coating.

The most important factor in the development of waterborne polyurethane coating is its low volatile organic chemicals (VOC) content, the characteristics of this makes it a variety of end use areas in better coating in green alternative choices, and thus drive the polyurethane coating market overall growth in consumption.

Polyurethane coating according to the terminal applications can be divided into the automobile coatings, aerospace coatings, home appliances coatings, architectural coatings, electronic products, such as paint, and also including transportation coatings, textile coatings, etc.

Automobile coating application in all fields dominated, polyurethane coating can provide the appearance of the automobile products with durability, scratch resistance, high gloss and corrosion resistance and a series of functions.

In the construction industry, polyurethane coating is also used for floor, coating and adhesives. Polyurethane coating is also used for making medical gloves and making furniture products.

In addition, since polyurethane coating is a product that combines flexibility, toughness and performance improvement, it is especially suitable for protecting electronic circuits. At the same time, the product has excellent mechanical and dielectric properties, and can provide strong coatings with high abrasion resistance.

The main driver of the polyurethane coating market is the growth in demand in the asia-pacific region, as well as in the automotive industry in North America, Europe and the Middle East.

In recent years, polyurethane coating products, applications and industries have expanded rapidly, becoming one of the fastest growing polymer composites industries. China has gradually become the world's fastest growing market center for polyurethane coatings, while the development of production, application and research has also been progressing rapidly.

With the rapid growth of domestic outfit, furniture coatings market in China, and the continuous improvement of the environmental protection laws and regulations and the relevant industry standards, especially water-based coatings waterborne polyurethane wood coatings market has started to become bright spot. In the next few years, we expect to see more than 20% of the market share of water-based wood coatings in the market.

In addition, the growing demand for construction and aerospace industries will also drive growth in the polyurethane coating market.

Due to the potential problems of the health hazards of polyurethane coatings, the increasing environmental safety regulations are expected to restrict the growth of the industry. In the future, the development direction of water-based polyurethane technology should be concentrated in the following aspects:

Efforts to improve the mechanical properties, solid content and adhesion strength of water-based polyurethane materials, especially the initial adhesion strength;

On the basis of further reduction of V0C, the mechanism of water based polyurethane crosslinking mechanism and the development of new crosslinking agent were developed, and the properties of the room temperature solidification of water-based polyurethane were improved.

Try to minimize the amount of organic solvents and eventually reach a solvent;

To solve the problem of the rich and low gloss of water-based polyurethane coating, develop high performance coatings, and actively explore new application areas;

The application of water-based polyurethane technology is solved by further reducing the cost of water-based polyurethane.

Basic theoretical research on strengthening and water-based polyurethane materials;

The effects of environmental temperature and humidity on the appearance of water-based polyurethane coating were carried out.

To strengthen the research and development of water-based polyurethane equipment.
