Q1: What is the primary function of Wacker CROSSLINKER V 88 in silicone formulations?
A: Wacker CROSSLINKER V 88 is a platinum-catalyzed addition-cure crosslinker designed to enable efficient network formation in heat-curable liquid silicone rubber (LSR) and high-consistency rubber (HCR) systems. It facilitates rapid, low-temperature curing with excellent control over pot life and final elastomer properties.
Q2: Is Wacker CROSSLINKER V 88 compatible with standard platinum catalysts used in LSR processing?
A: Yes — it is specifically formulated for use with conventional platinum-based catalysts, including Karstedt-type and Speier-type complexes. Compatibility is optimized for consistent reactivity and minimal inhibition by common formulation additives such as fillers, pigments, or inhibitors.
Q3: How should Wacker CROSSLINKER V 88 be handled and stored to maintain stability?
A: Store in original sealed containers at temperatures between 5 °C and 25 °C, protected from moisture, direct sunlight, and strong oxidizing agents. Avoid prolonged exposure to elevated temperatures or humidity, which may affect shelf life and catalytic efficiency.
Q4: Can Wacker CROSSLINKER V 88 be used in food-contact or medical-grade silicone applications?
A: When incorporated into fully cured silicone elastomers that meet relevant regulatory requirements (e.g., FDA 21 CFR, ISO 10993), and processed under validated conditions, Wacker CROSSLINKER V 88 supports formulations intended for food-contact and medical device applications. Final compliance depends on the complete formulation and manufacturing process.
