High-movement silicone bellows
system for protected deck applications beneath cover-plates, or at perimeters in decks,
stadiums, arenas, etc. Hydrophobic-acrylic-impregnated foam sealant, factory pre-coated with high-grade silicone. Watertight, odorless, clean handling, UV stable, non-staining, low temperature flexible, high-temperature stable. |

COMPOSITION: HORIZONTAL COLORSEAL is produced by coating an acrylic-impregnated open-cell polyurethanefoam with silicone. • The expanding foam is a patent-pending acrylic adhesive infused into the cellular foam base material. This new chemistry incorporates a hydrophobic microsphere component never before available in a sealant formulation. • The silicone external facing is factory applied at a width greater than maximum joint extension and is cured before final compression. • When compressed, a bellows is created in the coating. As the joint moves, the bellows fold and unfold; the silicone primary seal is thus virtually NEVER IN TENSION. • HORIZONTAL COLORSEAL is supplied in shrink-wrapped lengths (sticks). It is precompressed to less than the joint size. After insertion, it expands against the joint faces. • Non-invasive anchoring and sealing against the substrate is achieved through a combination of the backpressure caused by the stored strain energy of compression in the foam backing, the field-applied epoxy adhesive, and the field installation of a corner bead of silicone at the substrate-to-bellows interface.

ADVANTAGES: • Features the UV resistance, durability and impermeability of silicone. • Virtually eliminates tensile stresses at sealant bond line and adverse effects of movement occurring before curing in typical sealant-and-backerrod applications. • Both mechanically and chemically anchored through back-pressure inherent in the permanently elastic open-cell foam and the adhesion of the epoxy adhesive and through the field-applied silicone corner bead. • Reduces installation labor and materials, such as need for accurate positioning of a backer-rod, site mixing, tooling etc. • Twenty-six standard colors. • Supplied precompressed to less than joint size–no field compression required. DESIGN CONSIDERATIONS: • Metal coverplates (by others) must be installed above HORIZONTAL COLORSEAL where spiked-high-heel pedestrian traffic, or other high-pointload/small-contact-surface area loads are anticipated. • If movement exceeds ±50% (100% total) of joint-gap size at mean temperature, integrity of seal will be affected. • Capable of lateral ("shear") movements up to ±50% (total 100%) of joint size at mean temperature. • Substrates must be capable of resisting, without deflection, displacement, or deformation, at least 2.5 pounds of backpressure per square inch of the HORIZONTAL COLORSEAL material. • Standard sizes from 1/2" (12mm) to 10" (250mm). Other sizes available subject to review of application: consult EMSEAL. HORIZONTAL COLORSEAL is used for horizontal, deck applications that are protected from direct contact with traffic; for example, recessed slightly below concrete surface and covered with a metal plate, or located next to a wall or in other locations where no traffic, pedestrian or otherwise, can contact the product.Installed with field-applied epoxy adhesive and with a field-injected, silicone sealant anchoring band at each substrate-to-bellows interface. INSTALLATION: IMPORTANT: The following instruction summary is generic. Refer to "Install Data: Horizontal Colorseal" and job-specific instruction of EMSEAL technician for complete procedures. • Store indoors at room temperature. Expansion is quicker when warm, slower when cold. • Ensure material nominal size matches joint size. • Mix epoxy now and trowel onto joint faces. • Remove shrink-wrap packaging, hardboard, and release liner. • Wipe factory-applied release agent off silicone facing using clean, lint-free rag made damp with toluene. • Apply thin bead of silicone sealant along face of bellows at end where the material will join with next length. • Insert material into joint with at least a 1/4" (6mm) recess and adhere to one side. Material expands to seal joint. (Wedge larger-sized material in place while it expands.) • Blend silicone at butt joins into the silicone bellows to create a consistent finished appearance being sure not to restrict the folds of the bellows. • Once material has equalized its expansion across the joint, inject and tool a 1/4" x 1/4" (4mm x 4mm) corner bead at the substrate-to-bellows interface (see Fig. 1). (Note: unpainted metal surfaces and some natural stone surfaces may require priming -- consult EMSEAL.)
Patent Pending UNIVERSAL 90's HORIZONTAL COLORSEAL is manufactured in straight-run sticks which can be joined in the field to EMSEAL’s patent-pending "Universal-90" transitions.
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. |
