DESCRIPTION
Multifunctional epoxy and cycloaliphatic-amine based hardener for producing high performance composite parts. Two curing agents (4101-21 fast and 4101-21 slow) provide a complete range of working times from 30 minutes to 6 hours, and by blending the curing agents, any point in between.
Rhino 1401-21 with 4101-21 provides for ample pot life with fast cure development at standard molding temperatures. Rhino 1401-21 provides good thermal resistance, excellent fatigue and inter-laminar shear strength with rapid wetting of fiber reinforcements. Rhino 1401-21 Epoxy Resin is formulated for highly increased E-glass fiber compatibility. Low toxicity, low odor system, no VOCs, 100% solids.

Rhino 1401-21 Epoxy Resin is specially formulated for highly increased compatibility with fiber reinforcements, such as Carbon, E-Glass and CIPP Felt(s).
Rhino 1401-21 Epoxy Resin is formulated to improve the wet-out and bond between the epoxy resin and fiber reinforcements. This formulation technique results in increased physical properties as follows:
| • Fiber Pull-Out Strength | • Tensile Strength and Modulus |
| • Flexural Strength and Modulus | • Compressive Strength |
| • Impact Resistance | • Inter-Laminar Shear Strength |
Of equal, if not greater significance is the retention of the above properties after exposure to heat, cycle fatigue, water, expected adverse environmental reagents such as salt spray, acid rain, etc. The formulation of Rhino 1401-21 Epoxy Resin System results in minimal degradation of the cured composite’s physical properties as compared to epoxy resin systems not containing the proprietary formulation constituents of Rhino 1401-21 Epoxy Resin. The benefit to the composite fabricator is obvious and clear: Increased product life and confidence!
