Features & Benefits

• One component, polyurethane based adhesive.
• Combines high mechanical strength with the necessary elasticity to cope with high movements in facades.
• Secure application with good sag resistance.
• Bonds well to concrete, aluminium (anodized or powder-coated), rigid U-PVC, timber and other standard construction materials.
• Application of adhesive to one side only (mostly to substrate).
• Ensures levelling of substrate.
• No contact pressure necessary.
• Fast curing.
• Adjustment of membrane possible until 30 minutes after installation.

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.
• Treat non-porous surfaces with Sika® Aktivator-205.
• Clean porous surfaces by wire brush and/or vacuum.
• On porous substrates exposed frequently to water use Sika® Primer-3 N.
• Consider that these suggestions are based on experience and have in any case to be verified by tests on original substrates.

Application

• SikaBond® TF plus N 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 adhesive is between 15°C and 25°C.
• Until the adhesive is fully cured the substrate temperature must be in between 5°C and 40°C.
• To avoid condensation on the surfaces, the temperature of the bonding substrates must be at least 3°C higher than the dew point of the air.
• The skin time is significantly shorter in hot and humid climate.
• The SikaMembran® must always be installed within half of the skin time.
• Never join bonding parts if the adhesive has built a skin.
• SikaBond® TF plus N can be processed with hand, pneumatic or electric driven piston guns.

Removal

• Uncured SikaBond® TF plus N 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 a suitable industrial hand cleaner and water.
• Do not use solvents on skin.

Application Limits

• Where two or more different reactive sealants are used, allow the first to cure completely before applying the next.
• The compatibility of gaskets, backer rods, and other accessory materials with SikaBond® TF plus N must be tested in advance.
• Don’t use the adhesive directly on bituminous, plasticiser bleeding or formwork oil containing substrates.
