Toughened epoxy is optically clear and resists thermal cycling
Master Bond EP38CL was developed for bonding, sealing, coating and encapsulation applications that require toughness and durability. With a Shore D hardness exceeding 75, its toughness imparts resistance to rigorous thermal cycling, impact and mechanical shock.
EP38CL cures at room temperature or more quickly at elevated temperatures, and has low shrinkage upon curing. This low-viscosity, two-part epoxy has a 100:60 mix ratio by weight and a working life of 40-50 minutes. It bonds well to a variety of substrates including metals, ceramics, glass, composites, many rubbers and plastics. EP38CL features a tensile lap shear strength of 2500psi, a compressive strength of 8000psi and a tensile strength of 7500psi at room temperature.
In addition, EP38CL is optically clear with a glossy appearance. It is serviceable from -60degF to +250degF. This electrically insulative compound is used in optical, aerospace, opto-electronic and specialty OEM applications. It is available for use in standard packaging options ranging from 0.5 pint to 5 gallon kits as well as premixed and frozen syringes.
