Important instructions

Mixing & Dosage
Stir A and B thoroughly before each use. Use precise dosage in the specified ratio (see table above) — ideally by weight. Incorrect dosage will result in incomplete cross-linking.
Degassing
Degas the mixture under a vacuum of 30–50 mbar. The material expands 3–4 times, then contracts back to its original size after 5–10 minutes. Interrupt the vacuum several times for better degassing.
Avoid inhibitors
Polyaddition silicones are inhibited by: sulfur-vulcanized rubber, tin-catalyzed RTV, amine epoxides, and PVC with tin salts. If in doubt, conduct a preliminary test.
Application advice
SILITECH will advise you on the optimal RTV variant for your application — substrate, hardness, pot life, mechanics. Contact us with your specific application details.

Frequently asked questions about Silbione 4410 QC

Practical questions regarding processing and design — answered by SILITECH.

Silbione RTV 4410 1:1 QC A & B: Low-viscosity, very soft 2-component platinum silicone (Shore A 11) with very high elongation (780%) for liners, toe separators, and prosthetic applications — Quick-Cure variant. Main applications include liners for leg prostheses, heel cushions, and toe separators.

Polyaddition crosslinking is a two-component silicone chemistry using a platinum catalyst. Component A contains the platinum complex, and component B contains the SiH crosslinker. When mixed, the components crosslink without releasing reaction byproducts—no shrinkage due to outgassing, excellent dimensional accuracy, and low linear shrinkage. Important: Polyaddition silicones are inhibited by various substances—sulfur-vulcanized natural rubbers, tin-catalyzed RTV silicones, amine-catalyzed epoxy resins, and tin-stabilized PVC. In case of doubt, a preliminary test should be carried out.

Thoroughly stir components A and B before each processing step. Measure precisely according to the mixing ratio specified in the TDS (see comparison table above) – ideally by weight. Mix with an electric or pneumatic agitator at low speed (minimize air entrainment). Degas the mixture under vacuum (30–50 mbar) – the material will expand 3–4 times its original volume, bubbles will escape, and the material will settle back after 5–10 minutes. Then slowly pour into the mold from the lowest point to avoid air entrapment. For polyaddition systems, avoid contact with inhibitors (sulfur-based rubber, tin-based RTV, amine epoxides, PVC with tin salts).

Store in the unopened original container in a dry, cool place — typically between +5 and +30 °C, see TDS for exact values. Store components A and B separately; seal airtight after opening. Polyaddition systems are insensitive to moisture, but should be stored in a cool place to maintain pot life. Consult the Safety Data Sheet (SDS) before use.

The comparison table above lists related RTV products with different hardnesses, pot lives, or application profiles. If you are unsure which product is best for you, we would be happy to advise you — contact SILITECH with details of your application (substrate, desired hardness, processing time, mechanical requirements, and durability).
