Production operations of water-based PU adhesive

Water-based PU adhesive is a revolutionary product in the shoe manufacturing industry. It offers numerous benefits, including being eco-friendly and providing strong bonding. In this article, we will explore various aspects of using water-based PU adhesive in production operations.

What is the process flow for adhesive repairing?

The process flow for adhesive repairing using water-based PU adhesive is straightforward. First, clean the surfaces that need bonding. This ensures that there is no dust or debris that could affect adhesion. Next, apply the adhesive using a suitable brush or spray machine. Allow the adhesive to dry for a few minutes. Finally, press the surfaces together firmly to ensure a strong bond. The entire process is efficient and ensures durability.

Can water-based PU adhesives be used for white-colored shoes?

Yes, water-based PU adhesives are ideal for white-colored shoes. They offer excellent resistance to yellowing, which is crucial for maintaining the pristine look of white shoes. Additionally, these adhesives do not contain volatile organic compounds (VOCs), making them safe for both the user and the environment. The adhesive's strong initial adhesion and tensile strength ensure that the shoes remain intact and look good for a long time.

Can water-based PU adhesive and solvent-based PU adhesive be used together?

It is generally not recommended to bond water-based PU adhesive with solvent-based PU adhesive. The two types of adhesives have different chemical compositions and curing processes. Mixing them can lead to weak bonds and reduced durability. It is best to use one type of adhesive consistently for a particular application to ensure optimal performance.

What adhesive brushes are suitable for water-based PU adhesive?

When applying water-based PU adhesive, it is essential to use the right type of brush. Soft-bristled brushes are ideal as they allow for smooth and even application. Additionally, using a brush with synthetic bristles can prevent the adhesive from clumping and ensure a uniform coat. For larger surfaces, consider using a spray machine for more efficient application.

Conclusion

Water-based PU adhesive is a game-changer in the shoe manufacturing industry. Its eco-friendly nature, strong bonding capabilities, and resistance to yellowing make it an excellent choice for various applications. By following the proper process flow, using the right tools, and understanding its compatibility, manufacturers can achieve superior results. Choose water-based PU adhesive for a sustainable and efficient production process.
