Master Bond introduces EP38CL, an optically clear epoxy for coating applications and more

摘要

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 is a unique property that 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 2,500 psi, a compressive strength of 8,000 psi and a tensile strength of 7,500 psi at room temperature.
