1-component polyurethane adhesives

1-component polyurethane adhesives are the perfect choice for demanding bonding tasks in various industries. Whether in construction, the automotive industry, or crafts, these high-performance adhesives offer a flexible and durable solution for numerous applications. In this article, you will learn everything you need to know about 1-component polyurethane adhesives to achieve the best results for your projects.

Polyurethane – 1 Componant Construction Adhesive

Polysion Polyurethane is an elastic adhesive and sealant based on polyurethane. It adheres to all common construction substrates, most metals, polyester, and many plastics (with the exception of glass, PE, PTFE, PP, polystyrene, and silicone). Properties: Permanently elastic after curing and compensates for stressesHighly paint-compatible according to DIN 52452-A1Silicone-freeSandable after curingExcellent chemical resistanceVery good adhesion on many substratesResistant to seawater

What is single-component polyurethane adhesive?

Single-component polyurethane adhesive is a single-component adhesive manufactured on the basis of modified polyurethane (PU). These adhesives are characterized by their high elasticity, weather resistance, and strong adhesion to a wide range of materials. Unlike conventional polyurethane adhesives, polyurethane adhesives do not require additional moisture to cure—they cure under normal ambient conditions.

Advantages of single-component polyurethane adhesives

Easy to use: Since this is a single-component adhesive, there is no need to mix components. This saves time and reduces the risk of errors.
High flexibility: These adhesives remain flexible even after curing and adapt to the movements of the bonded materials, making them ideal for dynamic joints.
Wide material compatibility: 1-component polyurethane adhesives adhere excellently to various materials such as metal, plastic, glass, wood, and concrete.
Weather and UV resistance: These adhesives are resistant to external influences such as moisture, temperature fluctuations, and UV radiation, making them ideal for outdoor applications.
Environmentally friendly: Many polyurethane adhesives are solvent-free and low-emission, making them an environmentally friendly choice.

Areas of application for single-component polyurethane adhesives

Thanks to their versatility and performance, single-component polyurethane adhesives are used in various areas:

Construction: They are ideal for bonding facades, roofs, windows, and doors. They are also ideal for sealing joints.
Automotive industry: Here they are used for bonding car body parts, seals, and interior trim.
Furniture and woodworking: These adhesives offer strong adhesion to wood surfaces and are ideal for furniture production and repair work.
Marine and boat building: Due to their water resistance, they are perfect for use in humid environments, such as boat building.

Application tips for single-component polyurethane adhesives

Surface preparation: Ensure that the surfaces to be bonded are clean, dry, and free of grease, oil, or dust to ensure optimal adhesion.
Applying the adhesive: Apply the adhesive evenly to one of the surfaces to be bonded. Avoid applying too thick a layer to allow for even curing.
Bonding: Position the materials within the processing time and apply even pressure to ensure a strong bond.
Curing: Allow the adhesive to cure under normal ambient conditions. Note that the curing time may vary depending on the ambient temperature and humidity.

Conclusion

1-component polyurethane adhesives are versatile, high-performance, and user-friendly adhesives that are used in a wide range of industries. With their high flexibility, weather resistance, and strong adhesion to various materials, they are the ideal choice for numerous bonding tasks. Make sure you use them correctly and benefit from the numerous advantages these innovative adhesives offer.
