Bluesil RTV 3430 SB A

Product description

BLUESIL® RTV 3430 SB A is the soft and delayed main component for the RTV 3430 SB silicone system. Developed for applications requiring high detail accuracy and system durability, this component offers soft Shore hardness (approx. 30) and excellent tear resistance. The single-base system (A-component only) requires a longer curing time, but this enables bubble-free casting even with complex geometries. RTV 3430 SB A is ideal for molds with numerous undercuts, sensitive areas, or manual processing.

Processing instructions

1. Shake container well before use.

2. Pour into the prepared, clean mold.

3. If necessary, use vacuum processing to remove bubbles.

4. Room temperature curing: approx. 24–48 hours

5. Heat (up to 60 °C) can accelerate curing.

6. Demold after complete cross-linking

7. Avoid contact with substances containing sulfur, amines, or tin.

8. Storage: Keep sealed in an airtight container in a cool, dry place at 5–30 °C.
