FIRE STOP SYSTEMS

1. PRODUCT NAME A/D FIREBARRIER SILICONE SL 2. PRODUCT DESCRIPTION A primerless single component self- leveling silicone sealant. The sealant cures to a durable, flexible, silicone rubber when exposed to atmospheric moisture. Basic Use: A/D FIREBARRIER SILICONE SL is designed for use in firestopping configurations at slab-edge/exterior wall system intersections, at joints in horizontal assemblies, and at penetrations through fire-rated floor assemblies. A/D FIREBARRIER SILICONE SL forms durable, flexible, watertight bonds with most materials. In most cases, no primer is required. Composition and Materials: A/D FIREBARRIER SILICONE SL is designed to self-level. No tooling is required. Its physical properties will remain stable over time. It may be applied over a wide temperature range, -18°C to 50°C (0°F to 120°F), allowing the sealant to be applied in any season. Packaging: A/D FIREBARRIER SILICONE SL is available in nominal 304 mL (10.3 f 1. oz.) and 900 mL (30.5 f I.oz.) plastic cartridges, 7.6 L (2.0 U.S. gallon) and 17 L (4.5 U.S. gallon) bulk containers. Refer to the A/D Firebarrier estimate sheet for actual volume and coverage information. Colour: Dark grey. Application Limitations: Do not use where abrasion or physical abuse is anticipated. Do not apply in totally confined or air- free spaces. Silicones are paintable. However, movement of the silicone may cause the paint film to crack and peel. We recommend the sealant be applied after painting is completed. Because A/D FIREBARRIER SILICONE SL is self-leveling, it is limited to horizontal applications. Do not apply to surfaces with special protective or cosmetic coatings without prior consultation of the manufacturer and first testing adhesion. Do not apply to surfaces that will be in direct contact with food.   Standards: A/D FIREBARRIER SILICONE SL has been fire tested in accordance with the following: CAN4-S1 15-M, "Standard Method of Fire Tests of Firestop Systems". ASTM E814-83, Standard Method of Fire Tests of Through Penetration Fire Stops

4. INSTALLATION

Clean all openings to be firestopped by removal of foreign matter and contaminants such as oil, dust, grease, frost, water, surface dirt, old sealants or glazing compounds and any protective coating.

Priming: A/D FIREBARRIER SILICONE SL generally does not require priming. In view of the unpredictability of surface characteristics, it is recommended that a test sample of sealant be applied on the surface to test adhesion.

Masking: Areas adjacent to openings to be firestopped can be masked to assure a neat appearance. The masking tape should not be allowed to touch the clean surfaces to which the silicone is to adhere. Remove masking tape immediately.

A/D FIREBARRIER Mineral Wool is the required backup material for firestops. This material allows a thin layer of sealant to be applied for maximum economy.
Install backup material as specified. Application of 6mm (1/4") of A/D FIREBARRIER SILICONE SL to the face of 1 00mm (4") depth of A/D FIREBARRIER Mineral Wool provides up to a 3-hour fire rated firestop assembly. Top surface of Mineral Wool should be recessed a depth equal to the required thickness of sealant. Apply A/D FIREBARRIER SILICONE SL over Mineral Wool in sufficient quantity to fill and seal the opening to the specified depth. Excessive sealant should be dry- wiped from glass, metal, and plastic surfaces while still uncured, following with a commercial solvent such as xylol, toluol, or methyl ethyl ketone. CURED SEALANT MAY BE DIFFICULT TO REMOVE WITHOUT ALTERING OR DAMAGING THE SURFACE TO WHICH THE SEALANT HAS ADHERED.

Precaution: A/D FIREBARRIER SILICONE SL uses a neutral cure system. No acetic acid or objectionable byproducts are evolved during application. On direct contact, uncured sealant may irritate eyes. Flush with water and call a physician. Avoid prolonged contact with skin. Keep out of reach of children.

To safely use this product, read and abide by Material Safety Data Sheet.

Shelf Life: When stored in original unopened containers at or below 90°F (32°C), A/D FIREBARRIER SILICONE SL has a shelf life of six months from date of shipment.

5. MAINTENANCE

No maintenance should be needed. If silicone sealant becomes damaged, replace damaged portion. Clean surfaces in damaged areas, and repair with fresh A/D FIREBARRIER SILICONE SL.
