Foster® 32-80™ BRIDGING MASTIC ENCAPSULANT-LOCKDOWN



FOSTER ® BRIDGING MASTIC ENCAPSULANT-LOCKDOWN

Foster ® Bridging Mastic is a quality, dual-purpose coating designed specifically for the asbestos abatement industry.

Bridging Mastic is a field proven bridging encapsulant. Upon cure, 32-80 forms a tough, light colored, washable, abrasion resistant, elastomeric coating that economically abates the release of asbestos fibers from both conventional and spray applied asbestos-containing materials (ACM). Used with glass cloth, 32-80 is ideal for use over interior pipe covering and boiler lagging insulations.

Bridging Mastic can be diluted a maximum of 1:1 (water to 32-80) to produce an extremely effective lockdown (post-removal residual encapsulant). Applied at 400 sq. ft./gal., 32-80 cures to form a visible film effectively abating the release of remaining fibers.

BRIDGING MASTIC meets the requirements of NFPA 90A and 90B. Meets requirements for LEED IEQ 4.2 Low-Emitting Materials, Paints and Coatings. VOC: 41 g/l, less water and exempt solvents.

LIMITATIONS
Protect from freezing until dry. Not recommended for exterior use; select CP-211 instead. Do not store or apply below 40°F (4°C) or above 100°F (38°C). As a lockdown, do not apply to surfaces in excess of 170°F (93.3°C). Not suggested for use on floors. 04-08




COLOR:
Off-White

APPLICATION CONSISTENCY:
Brush, spray, or palm

AVERAGE WEIGHT/U.S. GALLON (ASTM D 1475):
10.5 lbs. (1.26 kg/l)

AVERAGE NON-VOLATILE (ASTM D 1644):
41.5% by volume

COVERAGE RANGE (FSTM 71):
(Subject to the type of surface being coated.) Wet coverages shown below are for smooth non-porous surfaces. Porous or rough textured surfaces will require higher gallonage to obtain required dry thickness.

As An Encapsulant

Dry Thickness: 0.025 inch (0.64mm) Equivalent Wet Coverage: 0.06 inch (1.52 mm) 3.7 gal./100 sq. ft. (1.5 l/m2 )

As A Lockdown
400 sq. ft./gal. (9.8 m2 /liter)

ODOR:
Mild when wet;
none when dry.

SERVICE TEMPERATURE LIMITS (FSTM 70):
(Temperature at coated surface of encapsulated ACM) 0°F to 170°F (-18°C to 77°F)

WET FLAMMABILITY (ASTM D 3278):
No Flash to Boiling (210°F/99°C)

SURFACE BURNING CHARACTERISTICS (ASTM E 84):
Flame Spread: 11
Smoke Developed: 2
Applied to 1/4 inch (6.4 mm) inorganic reinforced cement board at a coverage rate of 3 gallons/100 sq. ft. (1.22 liters/m2 ). The flame spread may vary at different product thicknesses and/or when applied over other surfaces. TM TradeMark of Specialty Construction Brands, Inc.
