SikaSwell® A is a rectangular acrylic sealing profile. It swells in contact with water to seal all types of construction joints and penetrations in concrete structures. Width: 20 mm, Height: 10 mm, Length: 10 m USES Joint sealing:
Pipe and steel work penetrations through walls and floor slabs
Around all types of penetrations and connection joints
Sikaflex is a premium-grade, high-performance, moisture-cured, 1-component, polyurethane-based, non-sag elastomeric sealant.
Designed for all types of joints where maximum depth of sealant will not exceed 1/2 in.n
Excellent for small joints and fillets, windows, door frames, reglets, flashing, common roofing detail applications, and many construction adhesive applications.
Suitable for vertical and horizontal joints; readily placeable at 40°F.
Has many applications as an elastic adhesive between materials with dissimilar coefficients of expansion.
Submerged conditions, such as canal and reservoir joints.
Eliminates time, effort, and equipment for mixing, filling cartridges, pre-heating or thawing, and cleaning of equipment.
Fast tack-free and final cure times.
High elasticity - cures to a tough, durable, flexible consistency with exceptional cut and tear-resistance.
Excellent adhesion - bonds to most construction materials without a primer.
Excellent resistance to aging, weathering.
Proven in tough climates around the world.
Jet fuel resistant.
Certified to the NSF/ANSI Standard 61 for potable water.
Urethane-based; suggested by EPA for radon reduction.
Paintable with water-, oil- and rubber-based paints.
Capable of ±35% joint movement
Surface 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. Install bond breaker tape or backer rod to prevent bond at base of joint.
