Metacaulk® 950 Water-Based Sealant 10.3 oz (Cream)

APPLICATIONS

Use Metacaulk 950 exclusively for interior conditions. Because Metacaulk 950 is water soluble it is not suitable for exterior or wet area use. See applications for Metacaulk 835+ for exterior or wet conditions. Metacaulk 950 is a general-purpose fire stop sealant for electrical, plumbing, plastic pipe and telephone communication systems penetrations. Use in vertical and horizontal applications, and for bedding and sealing small voids, splices and gaps. Metacaulk 950 is also an excellent fire rated acoustical sealant, and can be used around electrical outlets and non-vibrating construction joints. Use Metacaulk 950 to prevent the spread of fire through fire rated gypsum wallboard partitions, concrete block or concrete walls and/or concrete or wood floors. Consult application data for specific aluminum alloys before using Metacaulk 950 with aluminum pipe.

FEATURES & BENEFITS

• Metacaulk 950 is a one component fire-rated sealant for through-penetration fire stop systems. In the event of a fire, Metacaulk 950 will prevent the spread of flames, smoke, gas and water through penetration openings. It is formulated with noncombustible inorganic materials, therefore Metacaulk 950 will not create smoke or toxic gases when exposed to fire. Metacaulk 950 is to be used for interior applications only. It cannot be used in areas where there is continuous vibration on the through-penetration opening where wet conditions exist or may occur, or where there are continuous temperatures above 120 ̊ F (49 ̊ C). Metacaulk 950 is applied with a conventional caulking gun. Metacaulk 950 is a non-slumping sealant that sets to form a hard, yet retrofitable surface and can be used to seal static construction joints. Mixing is never required for installation. Metacaulk 950 systems are rated for 1, 2 and 3 hours in accordance with the ASTM E814 (UL 1479) and ASTM E1966 (UL 2079) test standards. Metacaulk 950 is protected in a wet stage as well as in a dry stage against mold growth with a combination of biocides.
