PRODUCT BENEFITS
UsageSikaflex-554 PowerCure is suitable for joints that will be subjected to dynamic stresses. Suitable substrate materials are metals, particularly aluminium, metal primers, paint coatings, sheet steel, ceramic materials and certain plastics. It bonds well to a wide range of substrates with minimal pre-treatment. Seek manufacturer’s advice and perform tests on original substrates before using Sikaflex-554 PowerCure on materials prone to stress cracking. Sikaflex-554 PowerCure is suitable for experienced professional users only. Tests with actual substrates and conditions have to be performed ensuring adhesion and material compatibility.Packaging

Technical Information CURE MECHANISM Sikaflex-554 PowerCure cures by reaction with the accelerator and largely independent from atmospheric moisture. For typical strength build-up data at 23 °C see table below. Time [h] Lap-Shear Strength [MPa] 2 0.25 4 0.7 8 1.2 24 2 Table 1: Strength build-up Sikaflex-554 PowerCure CHEMICAL RESISTANCE Sikaflex-554 PowerCure is generally resistant to fresh water, seawater, diluted acids and diluted caustic solutions; temporarily resistant to fuels, mineral oils, vegetable and animal fats and oils; not resistant to organic acids, glycolic alcohol, concentrated mineral acids and caustic solutions or solvents. | ||||||||||||||||||||||||||||||||||||||||||||||||
Application Information 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. All pre-treatment steps must be confirmed by preliminary tests on original substrates considering specific conditions in the assembly process. Application Set up the PowerCure Dispenser according the PowerCure User Manual. If the application is discontinued for more than 5 minutes, the mixer needs to be replaced. Sikaflex-554 PowerCure can be processed between 5 °C and 40 °C (climate and product) but changes in reactivity and application properties have to be considered. The optimum temperature for substrate and sealant is between 15 °C and 25 °C. Consider that the viscosity will increase at low temperature. For easy application, condition the adhesive at ambient temperature prior to use.
Figure 1: Recommended bead configuration Tooling and finishing Tooling and finishing must be carried out within the open time of the adhesive. We recommend the use of Sika Tooling Agent N. Other finishing agents or lubricants must be tested for suitability and compatibility. Removal Uncured Sikaflex-554 PowerCure may be removed from tools and equipment with Sika Remover-208 or another suitable solvent. Once cured, the material can only be removed mechanically. |
