Rapid Set


Multi-Purpose Hybrid Silane Polyether

DESCRIPTION: Rapid Set® Non-Sag Sealant is a single-component, multipurpose, fast curing, non-sag, 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. Non-Sag 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.

USES: Non-Sag Sealant is suitable for use in both exterior and interior applications. Its superior sag resistance makes it ideal for use on horizontal, vertical and overhead applications, including: filling wall joints, control joints, expansion joints, cove joints, and cracks; sealing windows, and door frames. It is engineered for use on exterior balconies, concrete floor slabs, driveways, garages, patios, walkways, and other vertical, horizontal, and overhead applications. This material provides excellent adhesion to Kynar 500 (PVDF coated metal), galvanized metal, aluminum, glass, cement board, brick, concrete, stone, EPDM and SBS-modified bitumen membranes, EPS foam, roofing materials, fiberglass (FRP), vinyl siding, and masonry. It can be used in damp, dry or cold climates, and its excellent adhesion characteristics make it ideal for application to damp concrete substrates.

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, BAAQMD 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 22 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 adhesive/sealant.

APPLICATION: 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). Typical width to depth ratio is 2:1. 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. If tooling is needed, do so within 15 minutes of application.

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 surfaces. Dispose of waste material in compliance with local regulations.

CURING: Tack-free in 40 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 Rapid Set® Non-Sag Sealant. To ease flow and placement in cold conditions, warm and keep the sealant to 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 sealant immediately.

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

PACKAGING: Available in single-component, 10.1 fl. oz. (299 mL) cartridge.

COLORS: Gray, White, and Sandstone.

COVERAGE: 10.1 fl. oz. (299 mL) yields 18.2 in3, 96 linear feet for 1/8" x 1/8" joints, 48 feet for 1/8" x 1/4" joints, 24 linear feet for 1/4" x 1/4" joints, 12 linear feet for 1/4" x 1/2" joints.

SHELF LIFE: Non-Sag 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 ½" depth. Do not use in continuous immersion applications. Allow treated wood and asphalt to cure for six (6) months prior to application of Non-Sag sealant. Do not apply on frozen substrates. Test and evaluate all paints and coatings before applying to Non-Sag Sealant. Polyurethane and oil based paints may dry slowly. White color will yellow with interior lighting.

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.

Refer to the Safely Data Sheet and www.CTScement.com for additional safety information regarding this material.

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, causes 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.

LIMITED WARRANTY: CTS Cement Manufacturing Corp. (CTS) warrants its materials to be of good quality and at its option, within 18 months from date of manufacture, will replace material proven defective or refund purchase price thereof, and such replacement or refund shall be the limit of CTS’s responsibility. Except for the foregoing, all warranties, expressed or implied, including merchantability and fitness for a particular purpose, are excluded.
