Weather Barriers - Sikaflex®-11 FC

One part advanced polyurethane, elastomeric sealant/adhesive

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 TT-S-00230C.

• Excellent adhesion on all cement-based materials, brick, ceramics, glass, metals, wood, epoxy, polyester and acrylic resin.
• Fast cure rate.
• Good weathering and water resistance.
• Non-corrosive.
• Can be painted over with water, oil, and rubber-based paints. (Preliminary tests recommended).
• High durability.
• Can be used in tamper resistant joints

Application

Application Information

Ambient Air Temperature

40 °F to 100 °F.

Sealant should be installed when joint is at mid-range of its anticipated movement.

Application Steps

SUBSTRATE PREPARATION

Clean all surfaces. Joint walls must be sound, clean, dry, frost-free, and free of oil and grease. Curing compound residues and any other foreign matter must be thoroughly removed. A roughened surface will also enhance bond.

Priming

Priming is not usually necessary for anodized aluminum, steel, non-absorbent materials such as glass, ceramics, stoneware and tiles. Most substrates only require priming if testing indicates a need or where sealant will be subjected to water immersion after cure. Consult Technical Service at 1-800-933-SIKA for additional information on priming.
