Chemical Resistant Polysulfide Joint Sealant - 2 Component

Product #OSVX572


Product #OSVX572 Polymeric Joint Sealant is a two-component chemically cured polysulfide sealant that provides excellent resistance to bioactivity and the harsh conditions encountered in wastewater treatment plants. Product #OSVX572 Polymeric Joint Sealant cures to a flexible rubber that provides a watertight seal between concrete, masonry, metals, glass, wood, and other construction materials. Product #OSVX572 is available in self-leveling.  Use OSVX573 for a non-sag consistency.


Product #OSVX572 bonds tightly to most clean, dry surfaces. Product #OSVX572 provides +/- 25% joint movement in temperatures as low as -10°F. Product #OSVX572 displays excellent resistance to heat, ozone, oxidation, sunlight and weathering. Product #OSVX572 is specially formulated to give resistance to bioactivity and chemical attack.


OSVX9573 is ideal when used as a joint system for:

  • Runways and Tarmacs
  • Jet Fuel Storage Secondary Containment Structures
  • Waste Water Treatment Plants
  • Road Salt Storage Sheds
  • Parking Garages and Driveways
  • Concrete Swimming Pools
  • Concrete Decks
  • Sidewalks
  • Parking Lots for Aircraft and Automobiles


Product #OSVX572 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


Tensile Elongation


ASTM D-638

Shore Hardness A Scale


ASTM D-2240

Service Range

-40°F (-40°C) to 250°F (121.1°C)



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

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


Product #OSVX572 meet the following specifications:

  • National Bureau of Standards and GSA TT-S-0227E (1970)
  • American Society for Testing & Materials (ASTM) C-920
  • Jet Fuel Resistance Meets Federal Specification SS-S-200E.


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.


Inspect joint slots to assure that they are clean and dry. To maximize bond to concrete, masonry, and steel, apply Product #OSVX572 Joint Primer and allow to dry. Primer must be used in constant immersion joints. Product #964 may be poured into joint. If you require a gun grade version of this product use OSVX573.

PRIMER: If a primer is required use OSVX JOINT SEALANT PRIMEROSVX JOINT SEALANT PRIMER is a one component moisture curing primer formulated to improve adhesion of our OSVX Joint Sealants. OSVX JOINT SEALANT PRIMER is easy to use and provides extra protection in applications where standing water or submersion will be present. OSVX JOINT SEALANT PRIMER acts to increase bond between organic and inorganic interfaces, binding together weak areas and creating a tough surface.


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.


Product #OSVX572 is available in 1.5 gallon (5.68 L) units.


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.


Six (6) months.


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.


Proper mixing and installation is critical to the optimal success of all product.  Seeee Installation Tips, Techdata, & MSDS for more details on our products.  Be sure to contact us with any questions and/or concerns that you have.
