Insight into market demand, Covestro empowers the automotive and furniture industry to upgrade with new raw materials for coatings and adhesives.

Improving Automotive Painting Efficiency

In the field of automobile manufacturing, the "wet-on-wet" process is being favored by greater and greater automobile OEMs due to its significant advantages in improving efficiency, energy saving, emit reduction and cost reduction. This process change of replacing traditional high-temperature baking with rapid low-temperature baking puts forward higher standards on the performance, stability and compatibility of original automobile paint. to this reason, Covestro has introduced a new polyurethane dispersion Bayhydrol specially designed to the automotive compact process in-coating products and base paint.®UH 2800.

The product has excellent low-temperature flexibility, aquatic environments resistance and anti-stone performance, can cope with extreme weather and complex road conditions, to provide solid protection to the body; at the same time, with excellent stability and breadth, adapt to different systems of "wet touch wet" coating products process. In addition, Bayhydrol®UH 2800 formula flexibility, can take into account one-component baking and low-temperature two-component baking applications, and because it does not add co-solvents, can significantly decrease the VOCs content of coatings, to help customers easily cope with increasingly stringent environmental regulations.

Optimizing Wood coating products Performance

In the process of accelerating the transformation of the furniture sector to aqueous coating products, companies still face some consumption difficulties, such as oil and tannic acid content of high wood after aqueous coating products is prone to tannic acid precipitation and oil leakage problems, affecting the adhesion and appearance of the paint film. In response to this pain point, Covestro has developed an innovative polyisocyanate curing agent Desmodur specifically to sealing primers.®E 11060.

With excellent sealing performance, the product can efficiently block the migration of tannic acid and grease in wood, and decrease the risk of subsequent coating products adhesion decline and film yellowing. It is suitable to one-component moisture curing system, convenient construction; excellent low-temperature drying characteristics make it even in the ecological stability close to 0 ℃, can still achieve overnight rapid grinding, help to shorten the coating products cycle. In terms of paint film performance, the product can enhance the pencil hardness and ethanol resistance of the paint film, thereby extending the service life of furniture. In addition, the scheme can still maintain low VOCs releases under the construction viscosity, and the paint film has low odor, which helps to create a healthier and safer coating products ecological stability.

Enabling Efficient Bonding in Soft Furniture

In the field of soft furniture, Covestro launched a patented product NeoCryl to sponge bonding.®A- 168 aqueous acrylic dispersion further expands the options to aqueous sponge bonding methodology. With efficient bonding as its core advantage, this product helps furniture manufacturers strike a stability between ecological preservation, performance and efficiency.

The product can achieve instant stick, no preheating or mixing, can significantly simplify the sizing process, shorten the production cycle, while maintaining excellent bonding performance. It is halogen-free and helps to meet the relevant chemical compliance standards of the EU market. The soft adhesive seam gives the finished product a better touch, and the excellent yellowing resistance helps to enhance the appearance condition and durability of the finished product.

Through the above-mentioned material innovation, Keschuang is helping downstream companies to strike a stability between ecological preservation, performance and production efficiency, and promote the environmentally friendly and sustainable research of the automotive and furniture sector.
