Sika Sikaflex 11FC One-Part, Advanced Polyurethane, Elastomeric Sealant/Adhesive - 10.1 Fluid Ounce Cartridge

Sika Sikaflex 11 FC is a one-component, gun-grade, adhesive and sealing compound of permanent elasticity. This dual-purpose material is based on a special moisture-cured polyurethane with an accelerated curing time that meets ASTM C920 Type S, Grade NS, Class 12.5, Use NT, I, M, G, A, O. and Federal Specification TTS-00230C. Sikaflex 11 FC offers excellent adhesion on all cement-based materials, brick, ceramics, glass, metals, wood, epoxy, polyester and acrylic resin. Sikaflex 11 FC has a fast cure rate, provides good weathering and water resistance, is non-corrosive and can be painted over with water, oil, and rubber-based paints. (Preliminary tests are recommended). Sikaflex 11 FC is highly durable and can be used in tamper-resistant joints.

Applications

As an elastic adhesive for:

• Cover plates, gaskets and coverings.
• Acoustic ceiling tiles.
• Floor moldings and door sills.
• Light weight construction materials.
• Wood or metal and door frames.
• Roof tiles.

As an elastic joint sealer for:

• Air ducts and high vacuum systems.
• Containers, tanks, and silos.
• Gaskets in openings in walls or floors for ducts, piling, etc.
• Reservoirs or water retaining structures.
• Aluminum fabrication.
• Bolted lap joints.

Limitations

• Allow 5 day cure at standard conditions when using Sikaflex 11 FC in total water immersion situations and prior to painting.
• Avoid exposure to high levels of chlorine. (maximum level: 5ppm).
• Maximum depth of sealant must not exceed 1/2" and minimum depth is 1/4"
• Maximum expansion and contraction should not exceed 12.5 % of average joint width.
• Avoid contact with alcohol and other solvent cleaners during cure.
• Do not apply when moisture-vapor-transmission condition exists from the substrate as this can cause bubbling within the sealant.
• Use opened cartridges the same day.
• When applying sealant, avoid air-entrapment.
• Since system is moisture-cured, permit sufficient exposure to air.
• White color tends to yellow slightly when exposed to ultraviolet rays.
• The ultimate performance of Sikaflex 11 FC depends on proper application, good design and proper preparation of joint surfaces.
• Not for use in expansion joints.
• Heavier substrates may require additional support during the cure period.
• Do not use in contact with bituminous/asphaltic materials.
