The main advantages of water-based polyurethane adhesives

2026,01,26

Water-based polyurethane adhesives are environmentally friendly polyurethane products that use water as the dispersion medium. In recent years, they have been widely used in various industries. Their main advantages are as follows:

Outstanding environmental performance and safety: The greatest advantage of water-based polyurethane adhesives lies in their use of water as the dispersion medium, with no or only a small amount of organic solvents. This significantly reduces the emission of volatile organic compounds (VOCs), improves the production and usage environment, reduces the hazards to operators' health and fire risks, and complies with increasingly strict environmental regulations.

Excellent bonding performance and applicability: This type of adhesive exhibits excellent adhesion to various substrates (such as wood, leather, textiles, plastics, metals, etc.). By adjusting the formula, the curing speed, initial adhesion, ultimate strength and toughness can be flexibly designed to meet different application requirements. The formed adhesive film usually has excellent flexibility, wear resistance and low-temperature resistance.

Excellent operational and processing performance: The water-based system has a relatively low viscosity, which makes it easy to penetrate porous substrates. It can be applied through various methods such as spraying, roller coating, and brushing. The cleaning of equipment is also extremely simple, requiring only water. This reduces the complexity of the process and production costs.

Outstanding compatibility and modifiability: Water-based polyurethane adhesives are easy to be physically blended or chemically modified with other water-based resins (such as acrylates, epoxy resins, etc.), thereby further enhancing their performance in specific aspects, such as improving water resistance, hardness or adjusting curing temperature, thus expanding their application scope.

Economy and storage stability: Although the cost of raw materials may be relatively high, due to its safe and environmentally friendly characteristics, it can save costs related to ventilation, explosion prevention, and waste disposal. The overall benefits are significant. Moreover, modern water-based polyurethane technology has enabled the products to have excellent storage stability.
