PU adhesives are versatile glues that have many benefits.
Ease of use is one of the biggest advantages of PU adhesives. They cure rapidly at room temperature to reach holding strength, and offer a range of handling times to accommodate complex assembly and clamp positioning, but can also be heated to speed up full cure. Precise application is required but mixing and special applicators are not needed. PU adhesives have multiple application methods and application can easily be automated.
Polyurethane adhesives create smooth, clean joints that enhance visual appeal of the finished product. Creating durable bonds that improve product longevity results in reduced requirement for repairs or replacements. In this way companies can offer high quality products whilst simultaneously managing expenses effectively.
PU adhesives are a smart choice for businesses that want to optimise operating budgets as they offer many different ways to economise. Not only is little adhesive required for a strong bond, but there is little waste due to the requirement for precise application. However, skilled labour is not needed and automation can easily be achieved, resulting in lower labour costs, and more streamlined production lines.
This one adhesive has so many applications that businesses can simplify procurement, reduce inventories of multiple adhesives and associated management costs, and take advantage of bulk purchasing discounts. Various formulations of PU adhesives boast a good shelf life.
Due to the low curing temperatures required by PU adhesives, energy consumption is reduced, reducing utility costs, and creating a more environmentally friendly, sustainable production process that enhances the brand image for consumers.
PU adhesives are available in 1k and 2k systems. 1k systems are generally less rigid, so are suitable for applications that require a degree of flexibility. They require the presence of water to cure and depending on your specific application, atmospheric humidity may be enough, for others water misting may be required prior to bonding of the second substrate.
2k systems create a stronger bond, have good gap filling properties, are superior in bonding rough materials, and have clear guidelines on full cure times.

FAQs & Troubleshooting
Always ensure that you are using your adhesive according to the instructions for your specific formulation. If you are having problems with your PU adhesives check that:
- You are applying the correct amount of adhesive
- There is enough atmospheric humidity or you are applying water mist with 1k systems
- You are using a clamp if required for your application
- You are using the correct formulation for your gap size
- One of the substrates is porous
- You are waiting long enough to achieve full cure
- You are using the correct applicator with 2k systems
