Coscat 83

Coscat 83 is a high-performance organobismuth catalyst (specifically a proprietary bismuth neodecanoate blend) manufactured by Aurorium (formerly Vertellus). It is primarily used in two-component (2K) polyurethane systems to drive the "gelling" reaction between polyols and isocyanates. BrenntagPalmerholland

Core Product Insights

* Key Functionality: It provides high selectivity for the polyurethane reaction and is notably moisture-resistant, preventing bubble formation or foaming in formulations. PalmerhollandSpecialchem

* Applications: Essential in CASE markets (Coatings, Adhesives, Sealants, and Elastomers), particularly for industrial floor coatings, aerospace finishes, and automotive sealants. PalmerhollandBrenntag

* Technical Profile: A clear liquid containing approximately 16% Bismuth, typically acting as a slower-speed catalyst that works effectively at room temperature. Palmerholland

Market Trends & Environmental Shift

* The Heavy Metal Exit: There is a significant market trend toward replacing toxic heavy metal catalysts like mercury, lead, and tin. Coscat 83 is a leading solution for this transition due to its excellent toxicity profile and compliance with environmental regulations like California Proposition 65. AlibabaAccio

* Sustainability Demand: Growth is driven by the industrial shift toward "green" chemistry, where low-toxicity catalysts are mandated in consumer and automotive applications. Accio

Sourcing & Availability

Verified distributors like Guangzhou Innovate Chemical Co., Ltd. offer Coscat 83 and related bismuth-zinc alloy catalysts for polyurethane systems.
