Preparation Tips:

Use clean containers for mixing.

Stir the silicone resin (Part A) thoroughly before use.

Shake the catalyst (Part B) before adding it to Part A.

Mix well with a flat stirrer or stick.

If needed, de-air the mixture in a vacuum chamber for 2-3 minutes.

Curing and Post-Curing:

For best results, allow the mold to air cure at ambient temperature (up to 50 C) for 24 hours before use.

Post-cure the mold for an additional 4 hours at 65 C to eliminate residual moisture and alcohol.

Work in a well-ventilated area.

Wear safety glasses, long sleeves, and nitrile rubber gloves.

Avoid latex gloves, as they may interfere with the curing process.

Keep the silicone resin and catalyst in securely closed containers during transport and storage.

Clean molds with soap solution before storing.

Store molds assembled on a level surface in a cool, dry environment.
