Soudaseal 240FC is suitable for a wide range of substrates commonly used in construction and building, including treated wood, PVC, and plastics. It provides excellent adhesion to metals such as steel, AlMgSi1, electrolytic galvanised steel, AlCuMg1, flame galvanised steel, AlMg3, and steel ST1403. The product also adheres well to plastics including polystyrene, polycarbonate (Makrolon®), PVC, ABS, polyamide, PMMA, fibreglass-reinforced epoxy, and polyester.
While Soudaseal 240FC adheres well to most plastics, it's important to note that plastics often contain releasing agents and processing aids that can interfere with adhesion. It's essential to remove any protective agents or foils before applying the sealant.
For porous surfaces in water-loaded applications, priming with Soudal Primer 150 is recommended. Non-porous surfaces should be treated with Soudal Cleaner & Degreaser to ensure proper adhesion. The product is not suitable for PE, PP, PTFE (e.g., Teflon®), bituminous substrates, copper, or copper-containing materials such as bronze and brass. Preliminary adhesion and compatibility tests are recommended for all surfaces.
Proper surface preparation is crucial to achieving the best results with Soudaseal 240FC. Start by ensuring that all surfaces are clean, dry, and free from dust, grease, and contaminants.
For non-porous surfaces, use Soudal Cleaner & Degreaser for thorough cleaning.
For porous surfaces in water-loaded applications, apply Soudal Primer 150 to ensure optimal adhesion.
When working with plastic surfaces, remove any releasing agents, processing aids, or protective foils that could hinder adhesion. Always perform a preliminary adhesion and compatibility test on each surface before application.
Begin by preparing the cartridge. Cut the nozzle at a 45-degree angle to the desired width and insert the cartridge into a caulking gun.
Apply continuous pressure on the trigger to dispense the sealant. Apply Soudaseal 240FC in a steady, even motion, ensuring full coverage of the intended area. Maintain consistent pressure to create a smooth, uniform bead.
Tool the sealant immediately after application using the Soudaglatt Smoothing Tool or a similar tool to achieve a smooth finish. Alternatively, use a wetted finger to create a neat appearance.
Allow the sealant to cure according to the manufacturer's instructions before subjecting it to any stress or moisture.
For adhesive applications, follow the surface preparation instructions mentioned above.
Apply Soudaseal 240FC evenly onto one of the surfaces using a suitable applicator.
Press the surfaces firmly together immediately after applying the adhesive, ensuring full contact. If necessary, secure the bonded materials until the adhesive sets.
Allow the adhesive to cure completely before subjecting it to any stress or moisture.
Coverage of any sealant product varies depending on Joint Width and Joint Depth.
Please refer to our Guide on How To Measure The Number of Tubes Required For the Job.
Minimum Width for Bonding: 2mm
