Foster® 32-32 BRIDGING ENCAPSULANT
FOSTER ® BRIDGING ENCAPSULANT
FOSTER Bridging Encapsulant is a pigmented single component, water based elastomeric product for use over interior fibrous and cementitious types of asbestos containing materials (ACM). It is easily spray-applied and after curing forms a tough, durable, elastomeric film over the ACM, effectively retarding the fallout of friable asbestos fibers.
Bridging Encapsulant can be applied to previously painted surfaces. It can also be used over the hard, non-absorptive types of asbestos insulation that will not "accept" a penetrating-type encapsulant.
Bridging Encapsulant can be used with glass cloth as a lagging adhesive and coating to encapsulate asbestos containing pipe covering and boiler lagging insulation.
Bridging Encapsulant has been extensively tested by Battelle Columbus Laboratories and is on the list of products deemed acceptable by the U.S. Environmental Protection Agency.
Bridging Encapsulant contains no asbestos, lead, mercury, or mercury compounds.
Keep from freezing. Do not store below 40°F (4°C) or above 100°F (38°C). Do not apply to surfaces below 40°F (4°C) or to surfaces operating at, or intended to operate at or in excess of 250°F (121°C).
Not suggested for use on floors. FOR INTERIOR USE ONLY.
DO NOT DILUTE.
+ These products have been tested for the U.S. EPA and found to satisfactorily seal asbestos insulation under restricted conditions. This does not constitute an endorsement or recommendation by EPA.

11.4 lbs. (1.37 kg/liter)
AVERAGE NON-VOLATILE (ASTM D 1644):
63% by weight; 49% by volume
SERVICE TEMPERATURE LIMITS (FSTM 70):
(Temperature at coated surface of encapsulated ACM) 0°F (-18°C) to 170°F (77°C)
AVERAGE COVERAGE RANGE (FSTM 71):
Subject to the nature of the material being coated.
Wet coverages shown are for smooth non-porous surfaces. Porous or rough textured insulation will require higher gallonage to obtain required dry thickness.
Dry Thickness: 0.025 inch (0.64 mm) Equivalent Wet Coverage: 0.05 inch (1.3 mm); 3.1 gal/100 sq. ft. (1.3 l/m2 )
Mild when wet; none when dry
Wet flammability (ASTM D3278) No flash to boiling, 205°F (96°C)
Surface Flame Spread (dry) (ASTM E84):
Flame Spread: 10
Smoke Developed: 5
Applied to 1/4 inch (6.4mm) inorganic reinforced cement board at a coverage rate of 3 gallons/100 sq. ft. (1.22 l/m2 ).
Surface Flame Spread (ASTM E162):
21 on 1 inch (25.4mm) sprayed mineral wool insulation. The flame spread may vary at different product thicknesses and/or when applied over other surfaces. Meets NFPA 90A and 90B 25/50 requirements and the building interior occupancy requirements of most building codes used in the U.S.A.
Meets requirements for LEED IEQ 4.2 Low-Emitting Materials, Paints and Coatings. VOC: 20 g/l, less water and exempt solvents. TM TradeMark of H.B. Fuller Construction Products Inc.
