FX-572

DESCRIPTION:

FX-572/573 Polymeric Joint Sealant is a two-component chemically cured polysulphide sealant that provides excellent resistance to bioactivity and the harsh conditions encountered in wastewater treatment plants. FX-572/573 Polymeric Joint Sealant cures to a flexible rubber that provides a watertight seal between concrete, masonry, metals, glass, wood, and other construction materials. FX-572/573 is available in self-leveling or non-sag consistency.

ADVANTAGES:

FX-572/573 bonds tightly to most clean, dry surfaces. FX-572/573 provides +/- 25% joint movement in temperatures as low as -10°F. FX-572/573 displays excellent resistance to heat, ozone, oxidation, sunlight and weathering. FX-572/573 is specially formulated to give resistance to bioactivity and chemical attack.

PROPERTIES:

FX-572/573 has excellent electrical resistance properties. Typical physical properties of cured material at 77°F (25°C) and 50% relative humidity are as follows:

Tensile Strength	85 psi
ASTM D-638	1.17 MPa
Tensile Elongation	250%
ASTM D-638
Shore Hardness A Scale	30-35
ASTM D-2240
Service Range	-40°F (-40°C) to 250°F (121.1°C)
Color	Gray

Pot life after mixing is approximately 40 minutes at 70°F (21.1°C).

Initial cure is 24 hours; final cure is 7 days.

SPECIFICATION:

FX-572/573 meet the following specifications:

National Bureau of Standards and GSA TT-S-0227E (1970)
American Society for Testing & Materials (ASTM) C-920

MIXING:

Mix entire contents of "B" Component into "A" with a slow speed mechanical mixer for 3 minutes. Mix well until color is uniform. Apply immediately after mixing.

APPLICATION:

Inspect joint slots to assure that they are clean and dry. To maximize bond to concrete, masonry, and steel, apply FX-572/573 Joint Primer and allow to dry. Primer must be used in constant immersion joints. FX-572 may be poured into joint. Apply FX-573 with either a caulking gun or a follower plate pressurized system.

COVERAGE:

Each 1.5 gallon (5.68 L) of mixed material will fill 346 cubic inches (5.7L) of joint slot, 115 ft. (35 meters) of 1/2" x 1/2" (12 mm x 12 mm) or 57 ft. (17 meters) of 1/2" x 1" (12 mm x 25 mm) joint slot.

PACKAGING:

FX-572/573 is available in 1.5 gallon (5.68 L) units.

LIMITATIONS:

Do not install in damp or wet joints. Ambient temperature should be above 40°F (4.4°C) at time of application to assure proper curing.

SHELF LIFE:

One (1) year

CAUTION:

Repeated or prolonged contact with skin should be avoided; protective gloves should be worn as a precaution. Avoid contact with eyes; in case of eye contact, flush with water for 15 minutes and consult a physician.
