FAQ
What are polyurethane sealants used for?
Polyurethane sealants are versatile sealing compounds used across construction, automotive, and industrial applications. They excel in sealing expansion joints, structural connections, façade elements, automotive body panels, and any application requiring durable, flexible sealing with strong adhesion. Common uses include weatherproofing building envelopes, sealing concrete joints, automotive bodywork repairs, and industrial equipment assembly where vibration dampening and long-term flexibility are essential.
Are polyurethane sealants paintable?
Yes, most of our polyurethane sealants are paintable once fully cured. The FOME FLEX PU FAST HM series specifically features paintability, allowing for seamless integration with painted surfaces. However, we recommend testing paint compatibility on a small area first and ensuring the sealant has fully cured (typically 24-48 hours depending on thickness and environmental conditions) before applying paint or coatings.
Is polyurethane sealant better than silicone?
Polyurethane sealants offer several advantages over silicone in many applications. They provide superior paintability, stronger adhesion to porous substrates like concrete and wood, and better resistance to abrasion and mechanical stress. Polyurethane sealants also offer excellent chemical resistance and can handle higher structural movement. However, silicone performs better in high-temperature applications and offers superior UV resistance. The choice depends on your specific application requirements, substrate materials, and environmental conditions.
Is polyurethane good for sealing?
Polyurethane is excellent for sealing applications due to its unique combination of properties. It offers exceptional adhesion to diverse substrates, permanent flexibility to accommodate structural movement, and superior resistance to weather fluctuations, chemicals, and mechanical stress. Our polyurethane sealants maintain their sealing integrity across temperature ranges from -40°C to +90°C, making them ideal for both interior and exterior applications. The material’s ability to remain elastic while providing strong adhesive bonds makes it particularly effective for dynamic joints and high-stress sealing applications.
Polyurethane sealants are widely used for construction, automotive, and industrial applications thanks to their durability and strong adhesion. Alongside PU products, there are also hybrid sealants, silicone sealants, acrylic sealants, specialized sealants.
