Rapid Set


Multi-Purpose Hybrid Silane Polyether

DESCRIPTION: Rapid Set® FLEXIBLE CONSTRUCTION ADHESIVE & SEALANT is a single-component, multipurpose, fast curing, strong, flexible adhesive and sealant that provides a durable elastic bond with 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. FLEXIBLE CONSTRUCTION ADHESIVE & 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: FLEXIBLE CONSTRUCTION ADHESIVE & SEALANT is ideal for a wide variety of adhesive and sealant applications, including: bonding concrete, masonry, brick, stone and plywood, expansion joints, precast concrete connections, weather sealing, windows, door frames, siding, cove joints, parapets, and other dissimilar materials. This high-performance material provides excellent adhesion to EPDM and SBS-modified bitumen membranes, aluminum, galvanized metal, steel, engineered plastics, PVC, glass, fiberglass (FRP), and EPS foam.

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 and caulks. 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 17 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 adhesives 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 and 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 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 the material cures on placement tools and adjacent surfaces. Dispose of waste material in compliance with local regulations.

CURING: Tack-free in 35 minutes, paintable in 24 hours at 70°F (21°C), 50% relative humidity.

COLD WEATHER: Installation in low temperatures will extend cure times of the adhesive/sealant. To ease flow and placement in cold conditions, warm and keep the adhesive/sealant 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/sealant immediately.

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

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

COLOR: Gray.

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

SHELF LIFE: Rapid Set® FLEXIBLE CONSTRUCTION ADHESIVE & 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 Flexible Construction Adhesive & Sealant. Do not apply on frozen substrates. Test and evaluate all paints and coatings before applying to Flexible Construction Adhesive & 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.

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

WARNING: AVOID CONTACT WITH SKIN AND EYES. Do not breathe vapors. Use product in well ventilated areas. Forced local exhaust is recommended to effectively minimize exposure. 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 epoxy material. Hazardous vapor is released when an epoxy is burned. For additional information, refer to precautionary statement.

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. CTS shall not be liable for any consequential, incidental, or special damages arising directly or indirectly from the use of the materials.
