PRODUCT BENEFITS
UsageSikasil WT-66 PowerCure has a wide adhesion range on many substrates such as glass, (coated) metal, PVC and others. Sikasil WT-66 PowerCure is used for back-bedding applications and bonding of insulating glass units into window frames. It`s structural capabilities enable a stiffening of the window sash. It is further suitable for industrial bonding and sealing applications. This product is suitable for experienced professional users only. Tests with actual substrates and conditions have to be performed ensuring adhesion and material compatibility.Packaging

Application Information Surface Preparation Surfaces 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. Application The optimum temperature for substrate and sealant is between 15 °C and 25 °C. Setup the PowerCure Dispenser according to the PowerCure User Manual. If the application is discontinued for more than 10 minutes, the mixer needs to be replaced. Joints must be properly dimensioned. Basis for calculation of the necessary joint dimensions are the technical values of the adhesive and the adjacent building materials, the exposure of the building elements, their construction and size as well as external loads. Tooling and finishing Tooling and finishing must be carried out within the open time of the adhesive. When tooling freshly applied Sikasil WT-66 PowerCure, press the adhesive to the joint flanks to get a good wetting of the bonding surface. No tooling agents must be used. Removal Uncured Sikasil WT-66 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. 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. Overpainting Sikasil WT-66 PowerCure cannot be overpainted. Application Limits Recommended solutions from Sika for structural glazing and window bonding are usually compatible to each other. These solutions consist of products such as Sikasil SG, IG, WS and WT series. For specific information regarding compatibility between various Sikasil products and other Sika products contact the Technical Department of Sika Industry. To exclude materials influencing Sikasil WT-66 PowerCure, all materials such as gaskets, setting blocks, sealants etc., in direct and indirect contact have to be approved by Sika in advance. |
