single-componentautomotiveprocess

Sikaflex®-223 is a low modulus 1-component polyurethane adhesive and sealant suitable for interior and exterior applications that bonds well to a wide variety of substrates. Its very good weathering resistance makes it suitable for exposed open joints, while its low elastic modulus allows the use of Sikaflex®-223 to bond and seal organic glasses (PC, PMMA). Good ageing and weathering resistance Suitable for bonding and sealing Easy to process and tool Suitable for a wide variety of organic glasses Areas of Application Sikaflex®-223 is a multi-purpose product for industrial sealing and bonding applications on most common substrates such as metals, GRP, 2-component coating and paint systems, plastics. Its very good weathering resistance makes it suitable for exposed open joints, while its low modulus allows the use of Sikaflex®-223 to bond and seal various organic glasses. Seek manufacturer’s advice and perform tests on original substrates before using Sikaflex®-223 on materials prone to stress cracking. This product is suitable for experienced professional users only. Tests with actual substrates and conditions have to be performed ensuring adhesion and material compatibility. Surface preparation Surfaces must be clean, dry and free from grease, oil, dust and contaminants. Surface treatment depends on the specific nature of the substrates and is crucial for a long lasting bond. Suggestions for surface preparation may be found on the current edition of the appropriate Sika® Pre-treatment Chart. Consider that these suggestions are based on experience and have in any case to be verified by tests on original substrates.
