- Instructions
- Be sure that all surfaces to be bonded or coated with 5995 silver epoxy are clean, dry, and free of any grease or oil.
- Thoroughly mix (by weight) 95-97% of Part-A and 3-5% of Part-B. Typical mixing times for small batches up to 5 grams is approximately 1 ½-2 minutes. After 2-3 minutes, the viscosity of the mixed material will begin to increase.
- Since 5995 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
95:5 (By weight)
- Pot Life
5-10 minutes at 20-25°C (3-5 gm mass)
