EK-93 / Part A  EK-93 / Part B

Lens Bond Type EK-93 is a non-toxic 100% solids epoxy system that is thixotropic and will not drip, sag, or shrink. Lens Bond Type EK-93 is an excellent structural adhesive that will bond virtually all like and unlike substrates with equal strength. It consists of a two-part formulation that is mixed in a 50/50 ratio. It has been tested and has been found to be resistant to solvents, oils and humid environments.

Approximate Curing Times

Pre-Cure Full-Cure
Due to the fact that the viscosity is very high, once applied, the substrates are held in place immediately and pre-curing is not necessary. At 50/50 ratio- 8 hours at 70캟 Pot life at 50/50 ratio- 90 minutes at 70캟 (ovens or infrared lamps may be used to accelerate cure speed)

Mixing Instructions

Approximately equal amount of "A "and "B" (by volume). Variations as high as 20% will not materially affect bond strength. When desirable, one part of "A "to 2 parts of "B "may be used to increase flexibility.
