The EP21NDCL two component epoxy system, which offers convenient handling with a one to one mix ratio by weight or volume, cures optically clear in thin sections, even though Part A is translucent and Part B is light amber. This non-drip compound is formulated for a variety of bonding, sealing and coating applications in the optical, opto-electronic, electrical, aerospace and specialty OEM industries. Upon curing, this epoxy features durable bonds with high tensile lap shear, tensile and compressive strength of 2,600-2,800 psi, 6,500-7,500 psi and 12,000-13,000 psi, respectively. It bonds well to many substrates, such as metals, composites, glass, ceramics, rubbers and plastics, particularly acrylics and polycarbonates.
