Handling & Curing Instructions
-
Preparation – Stir Components A and B separately before use.
-
Weighing – Weigh A and B in a 1:1 ratio.
-
Mixing – Mix thoroughly in a clean container. Stir in one direction to minimize bubbles.
-
Degassing – Vacuum degas for 5–10 minutes if required.
-
Potting – Pour into clean, dry housings. For large parts, consider staged potting.
-
Curing – Cure at room temperature (4–12 hrs) or heat at 80°C for 0.2 hrs.
Important Notes
-
Store sealed in a cool, dry place. Shelf life: 6 months.
-
Avoid contact with tin, sulfur, amine, phosphorus, or heavy metals – they inhibit curing.
-
Do not mix with condensation silicones, epoxy, or polyurethane.
-
Stir evenly to avoid partial non-curing.
-
Vacuum degassing after potting can improve thermal performance.
