CS-98 High-Build Ultra-Performance Epoxy Coating

Two-part, high-build, primerless, 100% solids, solvent-free epoxy coating for concrete and metal. Produces a thick durable polymer film that protects the surface from penetration when exposed to gasoline, oil, hydrocarbons, bases, acids, and many other chemicals. High-build formula allows for excellent coverage and protection over irregular shapes.

PERFORMANCE PROPERTIES

  • Thick, durable, solid coating after cure.
  • High-build polymer film protects against water intrusion.
  • Excellent chemical resistance.
  • Indoor application.
  • Cure time: 4 Hours @72°F (22ºC).
  • In service: 24 hours minimum.
  • Pot life after mixing (when transferred to paint tray): 30 minutes @77°F (25ºC), 1 hour @40°F (4ºC)
  • No blistering, peeling, or chipping when tested in accordance with ASTM G210-13 (23), “Severe Wastewater Analysis Testing” (SWAT).
  • No mass loss when immersed in 0.5 pH sulfuric acid in accordance with ASTM C1898-20, “Chemical Resistance of Concrete Products to Acid Attack”.

DESCRIPTION CS-98
Color: Part A: Color; Part B: Yellow-White/Dark Beige.
Mix Ratio A:B 2:1 ratio by weight, do not thin or dilute.
Mix Instructions: Stir each part separately. Add Part A into Part B and mix continuously until a uniform mixture is achieved. For proper performance, CS-98 must be mechanically mixed using a powered drill and paddle mixer. Start and stop drill with mixer blades fully submerged.
Application Method: Apply CS-98 using a brush, roller, or professional spray equipment.
Curing and Recoat: The coating will typically cure within 4 to 6 hours, with cure time decreasing at higher ambient temperatures. CS-98 will not cure effectively at temperatures below 40°F (4ºC). If an additional coat is required, lightly abrade the cured surface prior to reapplication to ensure proper adhesion.
Recommended Film Thickness: 30-mil dry (minimum). Apply liberally; no shrinkage upon cure (Dry film thickness is equivalent to wet film thickness).
Coverage Rate: 50 SF/gal (30-mil dry).
Clean Up: Mechanical scraping will be necessary to clean up cured product. CS-98 can be cleaned with denatured alcohol, MEK, or acetone while wet.
