Properties of Rhino R-908SC-RT Epoxy Resin
| Viscosity: | Thixotropic |
| Weight/gal: | 12.0 - 12.2 lbs per gallon |
| Color: | White, Light Blue or Gray |
Mixing
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 R-908SC-RT with any listed hardener at 100:12 by weight. Recommend mixing smaller batches Rhino 3102 due to its brief pot-life.
Curing
Allow the applied Rhino R-908SC-RT to cure past the tacky stage (see thin film set time), then immediately apply backup laminates. Once laminate schedule is completed, allow the structure to cure at ambient temperature (65° – 80°F) overnight. Ultimate properties and HDT of the completed part or tool may be improved by post-curing the structure. An initial post-cure at 130°F for 4 hours followed by an additional 2 hours each at 175°F and 225°F is the recommended post-cure schedule.
