Multi-Purpose Hybrid Silane Polyether

DESCRIPTION: Rapid Set® Self-Leveling Sealant is a single-component, multipurpose, fast curing, UV stable sealant that provides exceptional durability, superior weather resistance, and excellent adhesion to a wide variety of substrates. Its hybrid silane polyether-based chemistry and nanoparticle formulation enhances both adhesive and cohesive bond and prevents shrinkage upon cure. Self-Leveling Sealant promotes superior adhesion that outperforms the bond strength of polyurethanes, optimizes elongation, provides high tensile strength and flexibility, provides exceptional weather resistance, and will not outgas or foam on damp surfaces. This environmentally friendly formulation is low VOC, 100% solvent free, and contains no isocyanates (no harmful carcinogens). USES:

Self-Leveling Sealant is ideal for a wide variety of horizontal sealant applications, including: control joints, expansion joints and crack filling; sealing around pools and fountains. It is engineered for use on exterior balconies, concrete floor slabs, driveways, garages, patios, walkways and other applications. This material provides excellent adhesion to concrete, block, brick, stone, masonry, asphalt, wood, aluminum, galvanized metal, steel, and glass.

ENVIRONMENTAL ADVANTAGES: Low VOC, 100% solids, isocyanate-free products are ideal for applications where the presence of VOCs, fumes or vapors are unacceptable, undesirable or impractical. These products reduce the health risks of building occupants, installers and contractors; and contribute to improved indoor and outdoor air quality. Maximum durability and service life minimizes construction waste by-products.

REGULATORY COMPLIANCE: Conforms to OTC rule for sealants. Meets requirements of California Regulations: CARB and SCAQMD. This product does not contain cancer causing chemicals listed in California Proposition 65. Conforms to USDA Requirements for non-food contact.

GREEN STANDARDS: LEED 2.2 for new construction and major renovations: Low emitting materials (section 4.1) 1 Point. National Association of Home Builders (NAHB) Model Green Home Building Guidelines: 5 global impact points, VOC Content: Less than 19 grams / liter per ASTM D2369. EPA Method 24 (tested at 240°F/115°C).

SURFACE PREPARATION: Ensure substrate is clean, sound, and free of bond inhibitors, such as grease, oil, mold, surface water, coatings and sealers. For best results, roughen surfaces with an abrasive disc or sand paper, then wipe with acetone. Tape off or protect adjacent areas that should not receive sealant.

APPLICATION: Always maintain a width to depth ratio of 2:1. Apply between a minimum temperature of 35°F (2°C) and rising, and a maximum of 100°F (38°C). For best results, place sealants between 70°F (21°C) and 80°F (27°C). Do not apply if it is raining or rain is imminent. Cut the end of the nozzle at an angle for easy placement and insert the cartridge into a caulking gun. Before placing, extrude material until an even color (without streaks) flows out of the nozzle. Place nozzle at bottom of joint or application area to avoid trapping air during placement; keep the nozzle in the material during application. Maintain constant pressure on the caulking gun to avoid uneven placement. Carefully apply the sealant with a smooth continuous bead. Excellent self-leveling properties and smooth finish allow Self-Leveling Sealant to be installed without masking and tooling for experienced installers.

CRACK/JOINT FILLING: Place backer rod, where required, to prevent three-sided bonding. New concrete control joints and expansion joints (tooled or saw cut) must be free of surface water and other contaminates, and have at least 72 hours of cure before placement.

CLEAN-UP: Remove excess material using acetone and disposable paper towels or cloth rags before it cures on placement tools and adjacent surface. Dispose of waste material in compliance with local regulations.

CURING: Tack-free in 30 minutes, paintable in 24 hours at 1/4" at 70°F (21°C), 50% relative humidity.

COLD WEATHER: Installation in low temperatures will extend cure times of the sealant. To ease flow and placement in cold conditions, warm and keep the adhesive at 70°F (21°C) 24 hours prior to installation. Remove dew, frost or ice from the substrate with acetone on a clean cloth and place adhesive immediately.

WARM WEATHER: Installation in warm temperatures 80°F to 100°F (27°C to 38°C) will not adversely affect adhesive performance. Warmer temperatures will decrease viscosity and shorten cure time.

PACKAGING: Available in single-component, 10.1 fl. oz. (299 mL) and 28 fl. oz. (828 mL) cartridges.

COLORS: Light Gray, Gray, and Sandstone.

COVERAGE: 10.1 fl. oz. (299 mL) yields 18.2 cu. in.; 28 fl. oz. (828 mL) yields 50.5 cu. in.

(Sealants used in horizontal joints designed for vehicular traffic areas must be placed at a maximum width of 1" by 1/2" depth. Closed cell backer rod or bond tape is recommended to prevent three-sided bonding.

SHELF LIFE: Rapid Set® Self-Leveling Sealant has a shelf life of 18 months from the date of manufacture when properly stored.

STORAGE: Store in original, unopened container in a cool, dry, area. Protect unopened container from water, heat and direct sunlight. Store at 40°F to 90°F (4°C to 32°C). Elevated temperatures will reduce shelf life.

LIMITATIONS: Do not apply greater than 1" width and 1/2" depth. Do not use in continuous immersion applications. Allow treated wood and asphalt to cure for six (6) months prior to application of Self-Leveling Sealant. Do not apply on frozen substrates. Test and evaluate all paints and coatings prior to application to Self-Leveling Sealant. Polyurethane and oil based paints may dry slowly.

USER RESPONSIBILITY: Before using, read current technical data sheets, bulletins, product labels and safety data sheets. It is the user’s responsibility to review the instructions and warnings for any CTS products prior to use.

WARNING: AVOID CONTACT WITH SKIN AND EYES. NIOSH approved, organic vapor respirators and forced exhaust are recommended in confined areas, or when conditions (such as heated polymer, sanding) may cause high vapor concentrations. Do not weld on, burn or torch any hybrid silane polyether material. Hazardous vapor is released when a hybrid silane polyether is burned. For additional information refer to precautionary statement. Can cause skin irritation, may cause an allergic reaction, and cause serious eye irritation. Wear protective gloves, protective clothing, and eye protection. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice.
