SEISMIC COLORSEAL

STC 52 / OITC 38* 

SEISMIC COLORSEAL is ideally suited for ensuring watertightness in vertical and horizontal structural, seismic, and abutment joints in walls of precast concrete, brick, curtain-wall, stone, etc.

New!  NOW also available--SEISMIC COLORSEAL-DS (Double sided) for shallow-substrate applications.
 

SEISMIC COLORSEAL is the latest in an evolution of precompressed hybrid sealant technology.  Developed by EMSEAL in the early 1980's, precompressed hybrid sealants combine the best of liquid and preformed sealant features while eliminating the shortcomings of each.  SEISMIC COLORSEAL has an unmatched  20+ year track record of  performance.

Evolved from EMSEAL's COLORSEAL, SEISMIC COLORSEAL combines a factory-applied and cured silicone bellows with an impregnated expanding foam backing.  In contrast to COLORSEAL, the backing of SEISMIC COLORSEAL contains less foam, thereby freeing up volume for greater movement without stressing its components. The inherent secondary seal in the foam backing (as in the original COLORSEAL) is traded for the doubling of movement capacity and the silicone bellows does the waterproofing and acts as the weathering surface.
 

SEISMIC COLORSEAL features non-invasive anchoring which means you are not drilling and screwing into sensitive substrates. This eliminates the risk of spalls and enables installation into inside corners that are impossible to seal with screw-anchored strip-seals.

The expanding foam backing is acrylic-impregnated cellular foam combined in some sizes with laminations of closed-cell foam.  The impregnated foam contains no wax or asphalt compounds.

Backpressure from the stored strain energy of the precompressed foam secures the system to the substrate and ensures that the silicone bellows is never under tension from the effects of joint movement.

SEISMIC COLORSEAL has an R-value of approximately 2.15 per inch of depth which imparts thermal insulation at structural joint-gaps where thermal loss through strip-seals is often significant.

*Sound Attenuation is also a feature of SEISMIC COLORSEAL. With a 2 1/2" standard depth product installed in one side of a STC 56 wall, SEISMIC COLORSEAL had a STC 52 rating and in an OITC 38 wall it had a 38 OITC rating. When installed from both sides of a STC 68 wall it received the maximum of STC 68 equaling the sound suppression of the wall and in an OITC 52 wall it received a OITC 51 rating.

Unlike imitations that use closed-cell foam backings and that must be forced into compression in the field, SEISMIC COLORSEAL is supplied pre-compressed to smaller than the joint size.  This means that neither the bellows nor the corner bead, nor the foam backing are in tension either during the full extent of movement capability nor as a result of compression set typical in closed-cell foams.

SEISMIC COLORSEAL has a mounting adhesive on one face.  After removal from its packaging, the material is inserted into the joint and adhered to one side. It then expands to fill the joint. The combination of the active backpressure and the pressure-sensitive nature of the acrylic impregnation ensures the attachment of the foam to the other substrate.

Standard sizes from 1/2" (12mm) to 12" (300mm). 
Sizes up to 3/4" (20 mm) have single convex facing.
Sizes from 1" (25 mm) and bigger have multiple bellows coating.

Available in 12 standard colors. Custom Colors available.

Custom Colors:
In addition to the 12 standard colors, COLORSEAL products and WFR2 can be manufactured in custom colors. If you're having a custom color formulated for your project which is not in the Dow-790 palette of standard colors please contact EMSEAL to have us produce a matching color from another manufacturer or from silicone material shipped to us from that project. Contact Us.
 

HORIZONTAL COLORSEAL is manufactured in straight-run sticks which can be joined in the field to EMSEAL’s patent-pending "Universal-90" transitions.

Universal-90 Upturn Transition

Universal-90 Flipped-Over as Downturn Transition

These factory-fabricated single-piece 90-degree units have a 12-inch long leg and a 6-inch vertical piece on each side of the elbow. The Universal-90 transition pieces are symmetrically coated on both faces.  This allows them to be installed as an inside corner or as an outside corner.

In addition to guaranteeing watertightness, EMSEAL’s "Universal-90's" allow for much faster and secure installation by eliminating field cutting or notching and bending, at angles.
