Product description

BLUESIL® RTV 3132 B is the specially developed hardener component for the condensation-curing 2K silicone system RTV 3132 A. The combination of both components enables the production of high-precision, elastic silicone molds that are characterized by low shrinkage, good chemical resistance, and excellent tear resistance. The hardener allows for easy processing at room temperature and is suitable for a wide range of applications in industry, model making, replication technology, and decorative mold making. BLUESIL® RTV 3132 B ensures uniform curing and supports the optimal formation of mechanically robust, flexible molds.

Processing instructions

  1. Homogenize RTV 3132 A and 3132 B well before use.

  2. Mixing ratio 100:5 to 100:10 depending on the desired reactivity

  3. Mix without air bubbles, vent if necessary

  4. Pour into prepared mold or apply to model

  5. Curing at room temperature – complete cross-linking after 12–24 hours

  6. Demolding only after complete curing

  7. Do not use with materials containing tin, amines, or sulfur.

  8. Store product in a cool, dry, airtight place.
