RBC #1077 is a modified, low viscosity, UV stabilized resin with excellent clarity and air release properties. It is ideal for use as an industrial top coating in applications which require a tough semi-flexible coating. Superior air release properties eliminate the need for torching. This system offers a convenient 1:1 volumetric mix ratio.

The above properties are typical of a system cured with Hardener #AB-88.
AB-88: A low viscosity, medium pot life, room temperature cure hardener with excellent air release.
Pour the desired amount of # 1077 resin into a clean container and combine with recommended hardener in the ratio shown below:
| Hardener | By Volume | Pot Life 100 grams @ 25oC |
| AB-88 | 1:1 | 45 Minutes |
| Hardener | Cure @ 25oC | Cure @ 35oC | Cure @ 49oC | Cure @ 65oC |
| AB-88 | 18-24 Hours | 6 Hours | 3 Hours | 1 Hour |
