Description
Description: Easy Ink Stamps for Cool Shapes!
Topsil PY-30 is a high performance silicone for making printing pads.
This is a special two-component silicone rubber. Think of it like a craft kit with two parts. When you mix them, they harden at room temperature vulcanization (RTV). No heat needed!
This RTV-2 silicone is made just for pad printing applications. This is also called tampography supplies. It helps put ink on things that are not flat.
- Makes flexible printing pads.
- Great for silicone ink transfer.
- Perfect for precision pad printing.
Features:
Using Pad printing silicone has many advantages:
1.) very good flow
2.) High tear strength
3.) No impurities, good resilience and outstanding oiling
4.) Good printing effects
5.) Long shelf life
6.) Addition curing

Where Can You Use It?
This RTV-2 Pad Printing Silicone Rubber is great for many jobs:
- Medical Stuff:
- Putting logos on tools or parts. See our work with silicones for prosthetic application. Also for hygienic surface applications.
- Cars and Trucks:
- Making logos like BMW or Tesla emblems (automotive emblem printing). Used in making parts like Mustang rear-end gears 1 or parts for old cars like a 1958 Chevrolet Impala 2. Meets Automotive Industry Standards (AIS) and SAE International Automotive Standards.
- Toys and Gifts:
- Printing on round toys or cups (promotional merchandise industry). Good for custom logo embossing.
- Electronics:
- Marking small parts (electronic component marking). Can be electrostatic discharge (ESD) silicone or use anti-static additives.
- Kitchen Things:
- For printing on handles or tools (if using food-grade silicone rubber).
- Factory Use:
- Marking parts on an assembly line. Works with automated pad printers like KEBÖ® Pad Printing Machines, TAMPOPRINT® Automatic Printers, ITW Trans Tech®, or ERSA® Pad Printing Equipment. Can use hydraulic pad printers or rotary pad printers.
More Details Here:
| Feature | Detail |
| Type | Addition-cure silicone (also called Platinum-catalyzed silicone) |
| Temperature Use | Works from very cold (-50°C) to very hot (+200°C). Low-temperature flexibility. |
| Mixing | Usually 1:1 or 10:1 ratio. Control silicone viscosity control and pot life extension. Use silicone defoamers if needed. |
| Shrinkage | Very low silicone shrinkage rate. Keeps its shape (dimensional stability). |
| Color | Often clear or white. Can use color matching systems. Maintains ink opacity retention. |
| Special Types | Antistatic Pad Printing Silicone, thermal conductivity silicone, heat-cure silicone rubber, liquid silicone rubber (LSR). |
| Safety | Non-toxic, low off-gassing silicone. Meets UL 94 V-0 Flame Rating sometimes. |
| Compatibility | Works with cliché plate compatibility. Good for multi-color pad printing. |
| Alternatives | Better than some TPE (Thermoplastic Elastomer) alternatives or fluorosilicone alternatives for certain jobs. Compare to screen printing alternatives or industrial inkjet alternatives. |
| Related Processes | Liquid injection molding (LIM), compression-molded pads, multi-material overmolding, overmolding adhesion. Check silicone for rapid protyping molding. |
Who Makes and Uses This?
Many great companies work with this stuff!
- Makers:Dow Corning Silicones, Shin-Etsu Chemical Co., Wacker Chemie AG, Topsil silicone . Find a trusted Pad Printing Silicone Manufacturer.
- Users:Companies using Bosch Rexroth Automation, SCS (Specialty Coating Systems), TIGER Coatings Group, Henkel Loctite® Silicone Adhesives, 3M™ Flexible Materials Division.
- Ink Brands:INKMAC® Ink Solutions, Marabu Printing Inks, KISS® Technical Ceramics Inks. Modifiers like ink viscosity modifiers

- One of customer feedback:
- ‘ These silicone pads have significantly improved our print quality and reduced waste. The antistatic properties are essential for our work with electronic components. The customer service is also excellent.” – John S., Pad Printing Manager
Ink Transfer Efficiency by Silicone Pad Hardness
| Durometer (Shore 00) | Fine Detail (e.g., small text, intricate patterns) | Solid Coverage (e.g., large blocks of color) | Textured Surfaces (e.g., uneven substrates) |
| 10 | 70% | 80% | 95% |
| 20 | 85% | 90% | 90% |
| 30 | 95% | 95% | 80% |
| 40 | 90% | 95% | 70% |
| 50 | 80% | 90% | 60% |
| 60 | 70% | 85% | 50% |
This chart will provide a valuable visual aid for understanding the importance of selecting the right silicone pad hardness for achieving optimal pad printing results. Remember to adjust the data based on your specific product offerings and actual test results.
Storage:
Store in a cool and dry place 18 months from the date of production.
Warm Tips:
* It should be stored in a dry place in its original sealed container.
* Read the product safety data sheet(MSDS) carefully before using, which can be got from the supplier.
