What is TPUCO Waterborne PU Adhesive?
PU stands for polyurethane, a polymer commonly used in liquid and solid adhesives due to its high physical bonding forces and strong hydrogen bonds reinforced adhesion. Conventional PU adhesives have outstanding bonding strength and are resistant to washing temperatures, chemicals, and UV light. They can be categorized into solvent-based, water-based, and solvent-free PU adhesives. TPUCO Waterborne PU Adhesive is designed to be dispersed in water, making it easy to use and process. The water carrier is then eliminated prior to or during use, leaving the precipitated and coalesced PU polymer to form the adhesive bond. TPUCO Waterborne PU Adhesive is highly versatile and effective in bonding various materials together, making it increasingly popular in various industries, especially in textiles, packaging, printing ink, and footwear, due to its high versatility, eco-friendly, and zero VOC emissions nature.
Key Benefits of TPUCO Waterborne PU Adhesive
TPUCO
Waterborne PU Adhesive offers several key benefits, making it a popular choice in many applications. Firstly, the high shear stability and excellent film-forming properties of TPUCO Waterborne PU Adhesive are highly suitable for use in the textile industry. TPUCO Waterborne PU Adhesive can bond different layers of fabric, foam, and film together, creating a composite material with improved strength, durability, breathability, and waterproofing properties. This adhesive can also attach labels and patches onto fabrics, providing a solid and durable bond that can withstand washing and wear. Secondly, TPUCO Waterborne PU Adhesive can be easily applied by brushing, spraying, blade, or roller coating. Most importantly, using TPUCO Waterborne PU Adhesive is a significant step in reducing solvent emissions in the field of textile laminating and adhesive processing.
TPUCO Waterborne PU Adhesive for Footwear
In the footwear industry, shoes are manufactured from a variety of materials to optimize performance and production cost. TPUCO Waterborne PU Adhesive can bond different shoe parts together, such as the sole, upper, and lining. The adhesive provides excellent adhesion to various materials, such as leather, rubber, and fabric, to meet the requirements of high-performance adhesives for the increasingly complex composite shoe and sole structures. TPUCO Waterborne PU Adhesive can withstand the stresses and strains of daily use. It can also reinforce the toe and heel areas of shoes, which are particularly prone to wear and tear, prolonging the shoes' lifespan. Importantly, one of the key benefits of using TPUCO waterborne PU adhesive is that it is non-toxic, eco-friendly, and cost-effective. TPUCO Waterborne PU Adhesive is also being used increasingly in fashion footwear to replace solvent-based adhesives and ensure compliance with current and future VOC regulations. Another benefit of TPUCO Waterborne PU Adhesive is its low thermal activation temperature. This means it can be activated using heat below the melting point of many synthetic materials, such as polyester and nylon. This allows for a more energy-efficient bonding process, reducing the environmental impact of the footwear production.
Comparison Between Water-based and Solvent-based PU Adhesives
Due to eco-friendly concerns, many countries and brands prohibit adhesives with solvent content. More factories are switching to water-based PU adhesives, but many are asking, "Can water-based PU adhesives perform as well as solvent-based PU adhesives?" In comparison to solvent-based PU adhesives, water-based PU adhesives have a lower viscosity and higher solid content. If the lamination production line is properly designed, the drying rates and bonding strength of water-based PU adhesives can be comparable to solvent-based PU adhesives, and for some porous substrates, water-based PU adhesives may even perform better. Waterproofing and heat resistance properties of cross-linked water-based PU adhesives are not significantly different from those of solvent-based PU adhesives. However, the material production cost of water-based PU adhesives is higher than solvent-based PU adhesives. Higher material cost is one of the main reasons for the slower development of water-based PU adhesives. In fact, the solid content of water-based PU adhesives is generally higher than that of solvent-based PU adhesives. Water-based PU adhesives also emits fewer VOCs, reducing the cost of pollution control. Another aspect is occupational safety because water-based PU adhesives has no fire and explosion risks, thus avoiding costly investments in ventilation, safety, and solvent recycling. As processors become more familiar with the water-based PU adhesive process, the overall cost is not higher than using solvent-based PU adhesives.
In conclusion, TPUCO Waterborne PU Adhesive is a versatile and practical adhesive that offers excellent bonding strength and durability while being eco-friendly and cost-effective. Water-based PU adhesive can be used in various industries, including textiles, footwear, printing ink, packaging, automotive, etc., and offers several benefits over traditional solvent-based adhesives.
