Application Guidance
Surfaces must be clean, dry, and free from grease, oil, dust, and contaminants prior to application. Sikaflex®-295 UV can be applied between 10 °C and 35 °C, with optimal performance between 15 °C and 25 °C. Apply using manual or powered dispensing equipment and ensure parts are assembled within the open time. Tooling should be completed within the skin time, and adhesion testing on actual substrates is recommended before full application.
