Product Description

Sikaflex 11FC is a one component polyurethane joint sealant and adhesive. Sikaflex 11FC is a non-slumping material that cures by reaction with atmospheric moisture to form a tough and resilient elastomer. This product has a movement capacity of +/-10% and the shore hardness value of 40.

Technical and Environmental Benefits

• Low VOC, tested in accordance with Green Star NZ requirements.
• Local NZ Sika operations are ISO14001 certified. AT Facade is sourced from Sika Japan Manufacturing which is ISO 14001 certified (refer to attached certification schedule)
• Ready for use and requires no on-site mixing, meaning less product waste and no risk of faulty mixing.
• Approved for use in contact with potable water and in the food industry.
• High Shore A hardness.
• Excellent adhesion to most construction materials, even without primer.
• Fast curing.
• Good chemical resistance.
• High tearing strength.

Application and Purpose

Sikaflex 11FC can be used for a multitude of bonding, sealing (including forming gaskets) application, including, but not limited to:
- Filling and sealing construction joints in floors (Concrete, Ceramic, Stone)
- Rim and rebate sealing around pipes and ventilating ducts.
- Waterproof joints in potable water reservoirs.
- Bonding of lightweight building components e.g., tiles, brick slips, timber
- panelling, fibreglass, compressed sheeting, etc., to the structure.
- Bonding components together with different thermal coefficients e.g., aluminium, concrete, timber to steel, etc.
- Securing sanitary fittings to concrete or tiled floors or walls.
- Flange joints between ventilating ducts.

Note: Sikaflex 11FC will not adhere to polyethylene, polypropylene, polybutylene, Limitations polycarbonate, silicone or Teflon. If in doubt about the substrate suitability consult the Sika Technical Department or conduct preliminary adhesion tests.

Installation and Maintenance

All surfaces must be clean, dry and free from any loosely adhering particles or surface contaminants such as dirt, dust, oil, grease, etc. Establish depth by using rod or apply bondbreaker tape to the back-surface if required. Test adhesion without primer, use primer if necessary. Protect each outside face of the prepared joint with a layer of masking tape. Apply Sikaflex 11FC using a Sika hand or pneumatically operated caulking gun at an angle to eliminate the inclusion of air pockets. Sealant should be firmly extruded into the joint, making sure it is in full contact with the sides of the joint. Tool off sealant to achieve a smooth finish. Tooling will compress the sealant, promoting adhesion to joint walls. Remove masking tape before sealant starts curing.
