Premium Condensation Silicone Starter Kit for Professional Molds

Silicone Condensation 20 Starter Kit is a complete, ready-to-use set based on a 2-component tin-cure (poly-condensation) casting silicone with Shore A 23–26. The kit combines excellent flow properties (viscosity 24,000 ± 2,000 mPa·s) with a tensile strength of >3.92 N/mm² and an elongation of >400%, making molds accurate, flexible, and durable. Ideal for soap, candle, and concrete molds — for beginners who want to start immediately and for professionals looking for a reliable condensation silicone.

Key Benefits

• Complete all-in-one set: Silicone A-component, hardener (B), thickener (Thixo C), mixing cup, spatula, gloves, apron, and dosing syringe
• Shore A 23–26: Soft, flexible mold that releases well even with complex shapes and undercuts
• Pot life 30–40 minutes: Sufficient processing time for careful pouring and de-airing
• Shrinkage <0.3%: High dimensional accuracy for detailed reproductions
• Tensile strength >3.92 N/mm²: Durable molds for hundreds of casts
• Thickenable with Thixo C: Suitable for brush and spatula techniques on vertical surfaces

Typical Applications

• Soap molds for artisanal and industrial soap production
• Candle molds for decorative wax objects and candle makers
• Concrete molds for ornaments, decorative concrete molds, and architectural decoration
• Plaster molds for sculpture and art casting
• Lures (fishing bait) and model-making applications
• Honeycomb molds and decorative objects

Technical Characteristics

The Silicone Condensation 20 Starter Kit works with a mixing ratio of 100:5 (A:B by weight) and has a processing time of 30–40 minutes at room temperature. Full cure time is 960–1,200 minutes (16–20 hours); shrinkage remains below 0.3%. The viscosity of 24,000 ± 2,000 mPa·s ensures good flow into fine details without running off. By adding Thixo C (0.6–2%), the silicone is also suitable for spatula molds on vertical and inclined surfaces.
