Weight/gal:12.0 - 12.2 lbs per gallon


Use and store between 65° – 80°F. Surfaces must be free of contaminants such as dirt, oil, grease, or water. Wax or “release” mold surfaces before epoxy application. Mix Rhino 908SC with any listed hardener at 100:12 by weight. Recommend mixing smaller batches H-3102 due to its brief pot-life.


Allow applied 908SC to cure past the tacky stage (see thin film set time), then immediately apply backup laminates. Once laminate schedule is completed, cure the structure at ambient temperature (65° – 80°F) overnight. Then postcure at 130°F for 4 hours followed by a ramping schedule that increases temperature in 50°F increments for 1 hour to the intended service temperature or the limits of the backup laminate’s HDT.
