Chemical Resistance: tests are performed according the ASTM D543 –Practice A (Immersion test for 7 days at 25°C). The fully cured CHEM-GUARD 80 coating is resistant to:
* Small Surface Blisters.
Refer to manufacturer for resistance of other reagents.
Limitations: Application at ambient temperature below approximately 41°F (5°C) is not recommended. Exposure to temperatures exceeding 65°C for prolonged periods is not recommended.
Surface Preparation:
Concrete Substrate: As with all coatings it is imperative that proper surface preparation is achieved. Allow new concrete to cure, prepare by sandblasting or grinding. Surfaces should be sound or taken back to a sound base then reinstated where necessary. All grease, curing compounds, laitance or other deleterious matter should be removed.
Steel Surfaces: Minimum requirements of commercial sandblasting to SA 2½.
Galvanized Metal: Roughen up surface and degrease using solvents, ensure adhesion by testing.
Wood Surfaces: Sand smooth and remove contaminants.
Mixing: component B should be added to component A ensuring they are completely mixed. Mixing can be manual or by slow speed drill and mixing paddle.
Application: after thoroughly mixing the product, apply by either brush, roller, or airless spray equipment. Apply the first coat ensuring no pinholes are visible. The second coat should be applied after 6 hours at 77°F (25°C). Anti slip finish can be obtained by sprinkling silica aggregate 0.1-0.3 mm grain size into the first coat. Ensure that any loose aggregate is removed prior to the application of the second coat.
Cleaning: Remove uncured CHEM-GUARD 80 from tools and equipment with suitable solvents such as Xylene, Toluene or CHEM-CRETE BLENDED SOLVENT immediately after use. Cured material may only be removed mechanically.
At least one year in unopened cans. Containers should be stored in air-conditioned facilities.
Keep resin and hardener away from eyes and skin contact. Good ventilation should be provided particularly in closed work areas.
