Instructions: Be sure that all surfaces to be bonded or coated with 5921 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 10 grams is approximately 2 minutes.

Since 5921 silver epoxy is designed to be cured at room temperature (25°C) or with low heat, it is recommended that applications be made within 2-3 hours of mixing. After this time the material will exhibit drastic increases in viscosity.

For cleanup of uncured material use isopropyl alcohol.
Curing Schedule: 24-36 Hours at 25°C or 15 Minutes at 80-100°C
Mix-Ratio: 1:1 (by weight or volume)
Pot Life: 2-3 Hours at 20-25°C (3-5 gm mass)
