About This Product
Seismic Colorseal by Sika Emseal provides watertightness, thermal insulation, 100% movement capability, UV stability, and color coordination with substrates. It performs these multiple functions while incorporating no metals and no invasive anchoring.
In contrast to liquid-applied sealants, Seismic Colorseal is free of tensile stresses at the bond line and virtually free of tensile stresses in its low-modulus silicone facing. It is capable of movements up to ±50% (total 100%) of mean temperature joint size and provides a cost-effective, long-term, watertight seal.
Seismic Colorseal combines factory-applied, low-modulus silicone with an open-cell polyurethane foam infused with a water-based, non-drying acrylic dispersion. The external-colored silicone facing is factory applied while the foam is partially precompressed to a width greater than maximum anticipated joint extension and is cured before final compression. When fully compressed, a bellows is created in the coating. The bellows folds and unfolds during movement virtually free of tensile stresses.
Supplied precompressed to slightly less than its nominal size for ease of installation, it is packaged in shrink-wrapped lengths (sticks) with a mounting adhesive on one side. The shrink-wrap and hardboard packaging are removed, as is the release liner covering the mounting adhesive. The product is inserted into the joint and adhered to one joint face. It then expands to seal the joint.
Sealing against the substrate is achieved through a combination of the pressure-sensitive adhesive acrylic in the foam, the backpressure of the expanding foam and the field installation of a corner bead of silicone at the substrate-to-bellows interface.
