ELASTOSIL® RT 623 A/B — RTV-2 Silicone for Professional Pad Printing Pads

ELASTOSIL® RT 623 A/B is a two-component, addition-cured (platinum) RTV-2 silicone, specially developed for the production of pad printing pads and components requiring high-detail precision. The material features excellent flowability, stable mechanical properties, and fast curing without chemical shrinkage, ensuring consistent quality of the finished products.

Thanks to its carefully selected hardness and very high resistance to tearing and material fatigue, the silicone provides long service life for pads, even under intensive use in industrial processes. The stability of its properties over time helps maintain high print quality and precise paint transfer onto a variety of substrates.

Properties

ELASTOSIL® RT 623 A/B has low mixture viscosity, which facilitates degassing and precise mold filling, even with complex geometries. Its addition-curing system produces no by-products and ensures excellent dimensional stability after curing.

Once cured, the material forms an elastomer with high mechanical strength, excellent tear resistance, and flexibility, which translates into durability under repeated work cycles and dynamic deformation. The silicone maintains its properties over a wide range of operating temperatures and demonstrates good resistance to aging and UV exposure.

An additional advantage is the material’s uniform structure and stable hardness, which are crucial in pad printing processes where precision and repeatability are fundamental to the quality of the final print.

Applications

ELASTOSIL® RT 623 A/B is optimized for the production of components used in pad printing but also performs well in other applications requiring high-quality silicone elastomers.

Typical applications include:

• Production of silicone pads for pad printing

• Molding working components for precise ink transfer

• Manufacturing elastomeric auxiliary tools in technical printing

• Producing components that require high wear and deformation resistance

• Use in automated printing lines and industrial systems

The material performs especially well in applications demanding high durability, resistance to intensive use, and stable properties over long periods of operation.

ELASTOSIL® RT 623 A/B is a specialized RTV-2 silicone designed for professional pad printing. Its combination of excellent flowability, high mechanical strength, stable hardness, and zero shrinkage ensures process reliability, long pad life, and consistent print quality. It is the solution of choice for manufacturers prioritizing precision, durability, and production stability.
