Sikaflex 545 – 600ml – White Silane Terminated Polymer$ 22.91 DescriptionUsageSikaflex 545 (557109) is especially designed for applications which require a very high initial grab and a broad adhesion range. Suitable substrate materials include timber, glass, metals, metal primers and paint coatings (2-part systems), ceramic materials and plastics. Seek manufacturer’s advice and perform tests on original substrates before using Sikaflex 545 on materials prone to stress cracking. Sikaflex®-545 is suitable for experienced professional users only. Tests with actual substrates and conditions have to be performed ensuring adhesion and material compatibility.PRODUCT BENEFITSPowerful initial grabVery low emissionBonds well to a wide variety of substrates without the need for special pre-treatmentsExcellent workabilityFree of isocyanate, solvent and phthalateMeets highest EHS standardsEC1 certificateSurface PreparationSurfaces must be clean, dry and free from grease, oil and dust. 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.ApplicationApply the adhesive with a suitable caulking gun. Take care to avoid air entrapment in the joint. Sikaflex®-545 can be processed between 5 °C and 40 °C 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.RemovalUncured Sikaflex®-545 can be removed from tools and equipment with Sika® Remover-208 or another suitable solvent. Once cured, the material can only be removed mechanically. Hands and exposed skin have to be washed immediately using hand wipes such as Sika® Cleaner-350H cleaning towels or a suitable industrial hand cleaner and water.Do not use solvents on skin.Tooling and finishingTooling and finishing must be carried out within the skin time of the adhesive. It is recommended using Sika® Tooling Agent N. Other finishing agents must be tested for suitability and compatibility prior the use.OverpaintingSikaflex®-545 can be best painted within the skin formation time. If painting process takes place after the sealant has built a skin, adhesion could be improved by treating the joint surface with Sika® Aktivator-100 or Sika® Aktivator-205 prior to paint process. If the paint requires a baking process (> 80 °C), best performance is achieved by allowing the sealant to fully cure first. All paints have to be tested by carrying preliminary trials under manufacturing conditions. The elasticity of paints is usually lower than that of sealants. This could lead to cracking of the paint in the joint area.
