Why choose kneadable RTV 2 silicone?
Kneadable silicone, also known as silicone putty , is a two-component RTV2 system that you mix and shape by hand. It hardens at room temperature into a flexible to firm rubber.
These systems are ideal when liquid silicone is difficult to apply, providing excellent control for hard-to-reach areas and small repairs.
Curing mechanism: RTV 2 means room temperature vulcanizing with two components. Mix part A and part B according to the directions.
For: Mold makers, restoration and sculpting studios, prop and SFX workshops, culinary artists, and serious beginners who want to quickly create a precise, kneadable silicone mold.
Key Benefits
✓Simple application: knead, press, ready without formwork
✓Fast results , short processing times and fast curing
✓On-site control, perfect for hard-to-reach places
✓ Choice of varying hardness from very soft to firm
✓Food contact options selected lines suitable for chocolate molds
Application methods
→ Press the hand mold or push mold material around the object in one go
→ Close inlays and edges of seams, touch up or repair small parts
→Small flat objects medallions, pendants, decorative parts
Processing & curing
Ideal conditions
Temperature: Work at around 20 to 25°C on clean, dry models.
Environment: Avoid dust, oil and latex, follow pot life and disassembly time per product.
In addition systems: platinum-bound catalyst
In condensation systems: tin-bound catalyst
Both variants are available as kneadable silicone
Modifiers
Add pigments to colorless or white putty.
Release: Use a suitable release agent for epoxy, PU or polyester.
Suitable for casting with epoxy, polyurethane and polyester
See porous masters in advance
Spatula-friendly silicone
Besides kneadable silicone, there's also spatula-friendly silicone . These are thick and durable, and you apply them with a spatula to vertical surfaces for layering.
Advantage: Useful for larger surfaces and complex shapes where more control is required.
Tips for the best results
Mixing & processing
→ Measure accurately, mix A and B evenly
→ Mix until the color is uniform
→ Press putty in a thin, even layer
Application techniques
→ Carefully work away seams
→ Choose the correct release agent per system
→ Follow recommendations from product page
Food contact & storage
→ Use only food-safe lines
→ Follow any post-cure instructions
→ Store components in a cool, dry place
Compatibility with resins and casting materials
Kneadable silicone is suitable for casting with epoxy, polyurethane, and polyester . Choose the appropriate release agent for each system.
Important: See porous masters and follow the recommendations on the product page for optimal results.
