Liquid Rubber Materials Overview
Silicone Casting Rubber
- RTV Silicone: Room temperature curing, ideal for beginners
- Condensation Silicone: Easy to use, long processing time
- Addition Silicone: No by-products, perfect reproduction
- Shore A 20-40: Very flexible for complex shapes
- Shore A 50-70: Balance between flexibility and strength
Polyurethane Casting Rubber
- Flexible PU Rubber: Stronger than silicone, excellent wear resistance
- Fast systems: Curing in 15-30 minutes
- Slow systems: Up to 2 hours processing time
- Transparent grades: For visual control during pouring
Special Casting Rubber Types
- Food-grade rubber: Safe for kitchen and baking applications
- Heat resistant rubber: For high temperature applications
- Latex casting rubber: For thin, highly flexible molds
- Colored rubber: For recognizable and organizable molds
Professional Liquid Rubber Techniques
1. Direct Casting
Direct casting of liquid rubber for simple shapes and fast results.
2. Mold Box Casting
Controlled casting in closed containers for complex molds.
3. Vacuum Casting
Elimination of air bubbles for professional quality liquid rubber molds.
4. Layer-upon-Layer Pouring
For large objects or when material saving is important.
5. Brush Technique
For highly detailed objects where every texture must be preserved.
Step-by-Step: Using Liquid Rubber
- Object Preparation: Clean and prepare your original object thoroughly.
- Rubber Selection: Choose the Right Viscosity and Hardness
- Mold Preparation: Build container or prepare casting surface
- Sleep aid: Apply suitable sleep aid
- Mixing: Mix liquid rubber according to exact proportions
- Deaeration: Remove air bubbles using vacuum or stirring technique
- Pouring: Pour slowly and evenly in a thin stream
- Curing: Allow to cure completely (6-24 hours)
- Demolding: Carefully remove the original object

Common Liquid Rubber Problems & Solutions
Liquid rubber does not harden
Solution: Check the mixing ratio, temperature, and humidity. Ensure a clean work environment.
Air bubbles in liquid rubber
Solution: Use vacuum chamber, pour slower or use deaerator
Object sticks
Solution: Use more loose sleeping agent or choose another liquid rubber type
Incomplete filling
Solution: Check viscosity, increase casting pressure or use thinner liquid rubber
Details are lost
Solution: Use lower viscosity liquid rubber or brush technique
Pro Tips for Liquid Rubber Experts
- Temperature Control: Operate at a stable temperature (20-25°C) for optimal flow
- Viscosity Management: Choose the right thickness for your specific application
- Pot Life Planning: Take advantage of the long processing time for complex projects
- Casting Technique: Cast from a height in a thin stream for best results.
- Storage: Store liquid rubber in a cool, dry place for longer shelf life.
- Quality Control: Always test a small piece for large projects
