Foster® 32-21 / 32-22 PROTEKTOR® SEALANT
FOSTER ® PROTEKTOR ® SEALANT
Foster ® Protektor ® Sealant is a single-component, penetrating encapsulation coating for abating asbestos fiber fallout (retention method).
Protektor Sealant penetrates deeply into the asbestos containing materials, and then dries to form a firm, lightweight, damage-resistant surface.
Protektor Sealant has been extensively tested by Battelle Columbus Laboratories and is on the list of products deemed acceptable by the U.S. Environmental Protection Agency.
Protektor Sealant is produced under the classification and follow-up service of Underwriters Laboratories, Inc. It meets NFPA 90A and 90B 25/50 requirements.
As an Encapsulant -- do not store or apply below 40°F (4°C) or above 100°F (38°C). Protect from freezing until dry. As a Post Removal Residual Encapsulant -- do not store or apply below 40°F (4°C). Do not apply to surfaces operating at, or intended to operate at, temperatures in excess of 250°F (121°C).
+ 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.

WEIGHT PER U.S. GALLON (ASTM D1475):
8.5 lbs. (1.02 kg/l)
Mild when wet; none when dry
AVERAGE COVERAGE RANGE:
Subject to the thickness, absorbency and nature of the asbestos containing material (ACM) being encapsulated.
As An Encapsulant:
2 to 10 gal./100 sq. ft. (0.82 to 4.07 l/m2 ), applied in 2 coats of 1 to 5 gal./100 sq. ft. (0.41 to 2.03 l/m2 ) each.
As A Lockdown (See application guide):
Spray tests should always be conducted to determine actual on-the-job coverage rates, ideally duplicating the anticipated project application mechanics and environment.
SERVICE TEMPERATURE LIMITS (FSTM-70):
(Temperature at coated surface of encapsulated ACM) Minus 20°F (-29°C) to 250°F (121°C).
Wet flammability (ASTM D3278): No flash to boiling, 205°F (96°C)
SURFACE FLAME SPREAD (dry) (ASTM E84):
Flame Spread: 15
Smoke Developed: 0
Applied to 1/4 inch (6.35mm) inorganic reinforced cement board at a coverage rate of 10 gal./100 sq. ft. (4.07 l/m2 ).
SURFACE FLAME SPREAD (ASTM E162):
5 on 1 inch (25.4mm) sprayed mineral wool insulation. The flame spread may vary at different product thicknesses and/or when applied over surfaces other than inorganic reinforced cement board and sprayed mineral wool insulation.
