Surface Preparation & Application: <br /> Installation: <br /> Refer to the current UL/ULC Fire Resistance Directory for complete information or alternative approvals. The <br /> firestop system details will cover the required sealant depths,necessary amount of packing material and the <br /> permitted joint size or annular space. For exact"F"and "T" ratings and uses,ALWAYS refer to detailed <br /> drawings in the current UL/ULC Fire Resistance Directory or visit www.ul.com to access online information. <br /> 1. Apply sealant to clean, dry surfaces free of frost, grease and oil in temperatures above 40°F. <br /> 2. Cut nozzle at 45°angle to desired bead size and load into conventional caulking gun. <br /> 3. Puncture inner foil seal. <br /> 4. Hold cartridge at 45° angle and fill the opening around the penetrant (annular space) or the linear opening in <br /> the joint with the minimum specified thickness of sealant. <br /> 5. Do not apply to surfaces previously painted or treated with a sealer, curing compound, water repellent, or <br /> other coating without first getting confirmation from the coating manufacturer that their coating is <br /> compatible with BLOCKADE® Sealant. Remove coatings as required.Normally BLOCKADE® Sealant <br /> does not require priming for most common building materials. However, some special surfaces may require <br /> a primer. We recommend a trial application before starting a project to test adhesion. <br /> For Best Results: <br /> • Apply in temperatures above 40° F. <br /> • Store in a cool dry place between 40°F and 110°F. <br /> • Do not allow product to freeze. <br /> • For annular space exceeding 13/16", a backer support material of mineral wool is required. <br /> • Recommended only for use in passive fire containment systems specifically listed or approved for DAP <br /> Products Inc. in the UL/ULC Fire Resistance Directory. Do not apply over damp or contaminated surfaces. <br /> Not for use in stoves, fireplaces or other areas routinely exposed to high heat or flames, or for ASTM E-136 <br /> applications. <br /> Typical Physical & Chemical Characteristics: <br /> Solids: 60%min. <br /> Service Temperature Range: 157 to 1207 <br /> Application Temperature Range: 40°F to 110° F <br /> Tack Free Time: 30—60 minutes at 77°F, 50%RH <br /> Cure Time: 14 to 21 days depending on temperature,humidity,joint depth <br /> Density: 10.6 lbs./gal <br /> Paintable: Yes—after 4 hours <br /> Consistency: Gun Grade <br /> Shelf Life: 12 months <br /> Applications: Interior <br /> SDS No: 00077365001 <br />
