Description

Product Data Sheet

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, longterm, 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 externalcolored 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.

Uses

• For all joints 1/2-inch (12mm) to 10-inches (250mm).
• For small joints where a lasting alternative to liquid sealant and backer-rod is desired.
• Facades – Seismic Colorseal can be used in joints in building facades of masonry, precast concrete, brick, natural stone, metal curtainwall, window mullions, GFRP, EIFS and most other substrates.
• Inside Corners and Additions – Seismic Colorseal is uniquely suited to filling expansion joints at additions and particularly at inside corners. “Rubber-and-rail” alternatives cannot be properly installed at inside corners due to lack of access for drilling equipment. Seismic Colorseal uses no invasive anchoring and can be readily installed without violation of the substrates.
• Panelized Systems – Seismic Colorseal is ideally suited to sealing many panelized cladding systems that rely on “barrier-wall” sealing principles including metal cladding, window-wall systems, skylights, precast panels, etc.
• Transitions from Wall to Deck Joints – Transitions from vertical to horizontal-plane joints in parapets, walls, split columns, etc. are critical to watertightness and can be properly addressed using Seismic Colorseal. Transitions into other products by Emseal for waterproofing joints in decks, as well as into roof-joints, etc., are readily possible (consult Sika Emseal).
• Masonry Cavity Walls – As the visible seal in a cavity wall facade, Seismic Colorseal can in addition be installed in the structural backup to ensure continuity of the wall’s R-value and of the air/vapor barrier.
• Varying Joint Sizes, Curves, & Plane Changes – Joints vary in size due to construction tolerance buildup and because of substrate changes. Supplied to field-measurements, Seismic Colorseal accommodates joint size variations. It is pliable and can be conformed in the field to radii, and changes in plane and direction at soffits, and other architectural features.
