2120 Epoxy Hardener
2-Hour Pot Life Extends Work Time for System 2000
This long pot life hardener extends working time on large-scale and complex projects. Suitable for vacuum bagging and laminating in hot climates. The 24-36 hour de-mold time can be reduced by increasing the cure temperature. The post-cured service temperature exceeds 200 degrees F.
In sufficient mass, #2120 will cure completely at room temperature (77°F or above). However, when constructing 2 or 3 ply, thin laminates and when overnight demolding and sandability is required, heat must be applied. #2120 hardener should be given a cure of 12 to 14 hours at 120°F to 130°F to insure a hard gel sufficient for demolding and sandability. With higher cure temperatures, parts or molds will have a service temperature of over 200°F.
Pot Life: 120 Minutes
