TCS Brush Series for Large and Vertical Master Models
Four high-viscosity tin-cure silicone grades designed for controlled layer application on large, vertical and irregular surfaces without adding a separate thickener.
4 Grades
Brushable Range
Shore A 20–35
Flexible to Firm
100:3
Mix Ratio by Weight
40–60 min
Typical Working Time
Built for the Right Mold Geometry
Large sculptures, statues, vertical masters, architectural details and irregular surfaces where a poured block mold would use excess material.
Controlled Application
High viscosity helps the material stay on vertical and contoured surfaces.
Lower Material Use
Build the mold in layers instead of filling a large mold box with silicone.
No Added Thickener
Brushable consistency is built into the series for a simpler preparation workflow.
How to Choose a Starting Grade
Select by mold geometry and support requirement first. Validate performance with a sample before full production.
| Grade Range | Recommended Starting Direction |
|---|---|
| TCS-B20 | More flexible brush-on skins for detailed or more complex master geometry. |
| TCS-B25–TCS-B30 | Balanced brushability, flexibility and support for general sculpture and architectural work. |
| TCS-B35 | Firmer brush-on molds where stronger shape retention is required. |
TCS Brush Series Grade Comparison
Compare the available grades, then confirm the final selection against the current TDS and your production trial.
| Grade | Hardness (Shore A) | Mixed Viscosity (mPa·s) | Mix Ratio A:B | Working Time | Demold Time |
|---|---|---|---|---|---|
| TCS-B20 | 20 ± 2 | 35,000 ± 2,000 | 100:3 | 40–60 min | 8–12 h |
| TCS-B25 | 25 ± 2 | 38,000 ± 2,000 | 100:3 | 40–60 min | 8–12 h |
| TCS-B30 | 30 ± 2 | 38,000 ± 2,000 | 100:3 | 40–60 min | 8–12 h |
| TCS-B35 | 35 ± 2 | 40,000 ± 2,000 | 100:3 | 40–60 min | 8–12 h |
Typical values are for reference and are not specification limits. Results may vary with catalyst ratio, temperature, humidity, batch and test method.
Simple Processing Workflow
- Prepare: Clean and secure the master; apply a compatible release agent when required.
- Weigh: Measure base and catalyst by weight according to the current TDS.
- Mix: Blend thoroughly, scraping the sides and bottom of the container.
- Apply: Pour or brush according to the selected series and mold design.
- Cure: Leave undisturbed under the recommended conditions, then demold carefully.

TCS Brush Series FAQs
TCS Brush has a higher viscosity so it can be applied in controlled layers to vertical or irregular masters. Pourable grades are designed to flow into a mold box.
The series is formulated for brush application without an additional thickener. Confirm the desired build and application method with a sample trial.
Large or flexible brush-on molds commonly use a rigid support shell to maintain shape. The shell design depends on mold size, geometry and casting process.
