Premium Platinum-Cure Hardener for Professional Transparent Silicones
Wacker Vario Catalyst B-component is the essential hardener (catalyst) for Wacker Elastosil Vario Transparent 15 and 40 platinum-cure silicones. Available in two cure speeds - Normal (6 hours) and Fast (15 minutes) - for optimal flexibility in processing time. This high-quality catalyst makes it possible to create translucent, food-safe molds with minimal shrinkage and excellent mechanical properties. Please note: This is ONLY the B-component (hardener) - the A-component must be purchased separately.
Key Benefits
-
Flexible cure speed: Choose between Normal (6-hour demolding time) for ample processing time or Fast (15 minutes) for rapid production.
-
Blendable for intermediate speeds: Combine Normal and Fast catalysts for any desired cure time - see mixing ratio chart in datasheet.
-
Compatible with multiple Shore hardnesses: Works with both Vario 15 (Shore A 15) and Vario 40 (Shore A 40) A-components.
-
Platinum-cure quality: Minimal shrinkage (<0.1%), food-safe and skin-friendly according to FDA/TÜV guidelines.
-
Professional results: Translucent molds with excellent detail reproduction and high tensile strength.
-
Long shelf life: Minimum 1 year shelf life when stored correctly (5-25°C).
Typical Applications
- Rapid prototyping where visual inspection during mold cutting is essential
- Food-safe molds for chocolate, confectionery, fondant, and culinary creations
- SFX and prosthetics: skin-friendly molds for masks and special effects
- Podiatry and medical simulation for anatomical models
- Pad printing stamps and flexible printing applications
- Molds for polyurethane, epoxy, polyester, and acrylic resins where transparency is required
Compatibility:
Processing Instructions:
- Mixing ratio: 10 parts A-component : 1 part B-component (by weight)
- Ensure A and B components are from the same batch number for optimal performance
- Store between 5-25°C in a closed container for a minimum of 1 year shelf life
- Use gloves and work in a well-ventilated area

Mixing Calculator for Your Perfect Silicone
Calculate exactly how much Elastosil Vario 15, Vario 40, Catalyst Vario F (fast) and Normal you need.
All values at 20 °C. Temperature has a significant influence!
Disclaimer: This calculator is merely a tool and provides an estimate based on the graph from the manual. Actual pot life and cure time may vary due to temperature, mixing technique, humidity, or other factors. Siliconesandmore accepts no liability for divergent results. Always perform a small test mix first and consult the official manual.
Tip: Buy the kits separately if you want to adjust both hardness and speed.

Important Warning: Inhibition with Addition-Cure Silicones
Please note: This is an addition-cure silicone (platinum-cure). These silicones can be inhibited by sulfur, nitrogen, amino compounds, and metal salts. If you are unsure whether the products you are using (including gloves, spatulas, and cups) contain these ingredients, please perform a small test first. These substances can be found in many latex gloves, some plasticines, paints and glues, condensation-cure silicones, 1-component silicone sealants, natural rubbers, and 3D printing materials (especially stereolithography). If you wish to use these, you will need to apply a protective layer of polyvinyl alcohol (PVA).
