Q1: What is the primary function of Umicore Valikat Bi2810 in silicone rubber formulations?
A: Valikat Bi2810 is a platinum-based catalyst designed to promote efficient hydrosilylation curing in addition-cure liquid silicone rubber (LSR) and high-consistency rubber (HCR) systems. It enables rapid, uniform crosslinking at elevated temperatures while supporting excellent shelf stability in uncured compounds.
Q2: How does Valikat Bi2810 compare to standard Karstedt-type catalysts in terms of inhibition and processing safety?
A: Valikat Bi2810 incorporates proprietary thermal inhibition technology, offering extended pot life at ambient temperatures and reduced risk of premature cure during mixing or storage—particularly beneficial for high-shear LSR processing and multi-component dispensing systems.
Q3: Is Valikat Bi2810 suitable for medical-grade or food-contact silicone applications?
A: Yes—Valikat Bi2810 is formulated without heavy metals such as tin or lead and is compatible with regulatory requirements for medical device elastomers and food-contact materials when used in accordance with Good Manufacturing Practice and final formulation validation.
Q4: What are typical handling and storage recommendations for this catalyst?
A: Store in original sealed containers under inert atmosphere at temperatures between 5 °C and 25 °C, protected from moisture, direct sunlight, and oxidizing agents. Avoid contact with nitrogen-containing compounds, sulfur, phosphines, or heavy metal salts, which may cause irreversible deactivation.
