Soudafoam 2K can be used on a broad range of construction materials, thanks to its exceptional primerless adhesion capabilities. It adheres well to surfaces such as concrete, wood, plastic, and metal, ensuring reliable and long-lasting results.
To ensure optimal performance, the surface should be clean and free of grease and dust. Grease and dust can interfere with the product's adhesion and performance. Therefore, thoroughly clean the surface before applying Soudafoam 2K.
Recommended Can Temperature: The can should be stored and used between 10°C - 25°C.
Prepare the Area: Before activating the can, make sure that doors and/or windows are properly positioned to avoid obstructions during application.
Activate the Can: Turn the inner black disk on the bottom of the can 5 times to the right. This motion punctures the seal, allowing the components to mix.
Shake the Can: Firmly shake the can for at least 20 times, ensuring the valve is pointed down. This agitation helps to ensure proper mixing of the components.
Attach the Applicator: Apply the applicator onto the valve.
Apply the Foam: Point the valve downward and start applying the foam. The foam will expand upon contact, so be prepared to control the foam and adjust the coverage as needed. The extruded foam should have a solid light-green color. If not, repeat the activation steps.
Finish and Clean: To avoid curing inside the can, it is essential to completely empty the can within 5 minutes after the mixture of the components. If necessary, cover and tape up the substrate and adjacent materials. Fill the joint for 1/3, as the foam will expand further during curing.
Spilled Foam: Immediately remove spilled foam with Soudafoam Gun & Foam Cleaner. This specially formulated cleaner is designed to dissolve and remove uncured foam quickly and effectively.
Cured Foam: If the foam has cured, it must be removed mechanically or with Soudal Cured PU Foam Remover. This remover is specifically designed to dissolve cured foam, making it easier to remove from surfaces.
Take the usual labour hygiene into account.
Always wear gloves and goggles during application. See our Safety & PPE Products.
Consult label and material safety data sheet for more information.
A) To activate Soudafoam 2K, follow these steps: First, ensure the can is at room temperature for optimal performance. Turn the inner black disk located at the bottom of the can five times to the right. This action punctures the internal seal, allowing the base and isocyanate components to mix. After puncturing the seal, shake the can vigorously for at least 20 times while holding the valve pointed downwards. This ensures the two components are thoroughly mixed and the foam is ready for application. Remember, once activated, Soudafoam 2K must be used within a short time frame to take advantage of its rapid curing properties.
A) Yes, Soudafoam 2K can be used to insulate around electrical outlets due to its excellent thermal and acoustic insulation properties. However, ensure the electricity is turned off and avoid direct contact with wires or devices.
A) Absolutely, it's ideal for sealing around plumbing pipes. Its rapid curing and expansion properties effectively fill gaps, providing airtight and watertight seals that prevent water and air leakage.
A) Soudafoam 2K is best applied within its recommended application temperatures of +10°C to +25°C. While it can cure independently of atmospheric moisture, performance might be compromised in temperatures outside this range.
A) Soudafoam 2K has a fast curing time, with skin formation occurring in about 9 minutes and cutting time in about 15 minutes. It becomes fully loadable after approximately 4 hours for a 30mm foam bead.
A) Technically yes, Soudafoam 2K Fast Curing Expanding Foam may be classified as a closed-cell foam, with its structure comprising approximately 81% closed cells once cured, according to ISO4590 standards. This high proportion of closed cells imbues the foam with superior thermal and acoustic insulation properties, as the air trapped within these cells acts as an effective barrier against heat transfer and sound waves. Additionally, the closed-cell nature of Soudafoam 2K enhances its water resistance, significantly reducing the foam's permeability to moisture. This characteristic not only prevents water ingress but also contributes to the foam's structural integrity and durability, ensuring it retains its shape and size without succumbing to shrinkage or expansion after curing. The closed-cell structure thus makes Soudafoam 2K an excellent choice for a wide array of applications requiring reliable insulation, moisture resistance, and long-term stability.
