- Instructions
- Be sure that all surfaces to be bonded or coated with 5933 silver epoxy are clean, dry, and free of any grease or oil.
- Thoroughly mix equal amounts (by weight or volume) of Part-A and Part-B. * Typical mixing times for small batches up to 5 grams is approximately 1 ½-2 minutes. After 3-4 minutes, the viscosity of the mixed material will begin to increase. Larger quantities of mixed material exceeding a total of 6 gm is not recommended and may cause excessive heat and/or a significantly shorter pot life.
- Since 5933 silver epoxy is designed to be a “Rapid Cure Adhesive”, it is recommended that applications be made within 2-5 minutes of mixing. After this time the material will exhibit drastic increases in viscosity.
- For cleanup of uncured material use acetone, isopropyl alcohol, or MEK.
- Curing Schedule
16-24 Hours at 25°C or 10 Minutes at 80-100°C
- Mix-Ratio
1:1 (by weight or volume)
- Pot Life
3-5 Minutes at 20-25°C (3-5 gm mixed mass)*
