Application Guidance
Surfaces must be clean, dry, and free from grease, oil, and dust before application. Sikaflex®-505 UV can be processed between 5 °C and 40 °C, with optimum substrate and process material temperature between 15 °C and 25 °C. Tooling and finishing should be completed within the skin time, and adhesion and compatibility should be verified on original substrates before production use, especially on materials prone to stress cracking.
