Highly selective palladium-based heterogeneous catalyst for vinyl acetate monomer (VAM) synthesis.
Optimized for long-term stability and consistent activity under industrial fixed-bed reactor conditions.
Engineered with controlled metal dispersion and tailored support porosity to minimize sintering and carbon deposition.
Low palladium leaching performance ensures compliance with stringent environmental and process safety standards.
Compatible with standard VAM plant regeneration protocols, enabling extended catalyst cycle life.
Vinyl acetate monomer (VAM) production via acetic acid and ethylene gas-phase reaction.
Large-scale petrochemical plants operating continuous fixed-bed VAM reactors.
Integrated chemical complexes where high catalyst reliability supports downstream polymerization processes.
Greenfield and brownfield VAM facilities requiring low-risk, drop-in catalyst replacement solutions.

Q1: What is the primary application of WACKER CATALYST C 05?
A: WACKER CATALYST C 05 is specifically designed to accelerate hydrosilylation reactions in silicone-based systems, particularly for the production of addition-cure liquid silicone rubbers (LSRs), heat-cure silicones, and specialty silicone gels and coatings.
Q2: How should WACKER CATALYST C 05 be handled and stored?
A: This catalyst is moisture-sensitive and must be stored under inert atmosphere (e.g., nitrogen or argon) at cool, dry conditions, preferably between 2–8 °C. Avoid exposure to air, humidity, or elevated temperatures to maintain activity and shelf life.
Q3: Is WACKER CATALYST C 05 compatible with platinum-based inhibitors?
A: Yes — it is formulated to work effectively with common platinum inhibitors such as ethynylcyclohexanol or maleates, enabling controlled pot life and reliable cure onset in addition-cure formulations.
Q4: What is the typical dosage range for effective catalysis?
A: Dosage depends on formulation requirements and desired cure profile, but it is typically used at low concentrations — generally ranging from 0.1% to 2% by weight relative to the silicone polymer base.
