Custom Manufacturing, Project Outsourcing, your Trusted Partner from China
NINGBO INNO PHARMCHEM CO.,LTD. is pleased to highlight its offering of Karstedt's Catalyst, a leading liquid platinum catalyst with the CAS number 68478-92-2. Known chemically as Platinum(0)-1,3-divinyl-1,1,3,3-tetramethyldisiloxane complex, this catalyst is indispensable for catalyzing the addition reaction between vinyl-functionalized silicones and hydrogen-terminated silicones, a process critical for forming robust and durable silicone elastomers and resins.
Karstedt's Catalyst is widely recognized in the silicone industry for its exceptional catalytic activity and ability to facilitate rapid curing at relatively low temperatures. This makes it a preferred choice for a multitude of applications where efficient and reliable cross-linking is paramount. Unlike catalysts that require high heat or generate byproducts, Karstedt's Catalyst enables a clean addition cure, often referred to as hydrosilylation, resulting in stable and high-performance materials.
The product supplied by NINGBO INNO PHARMCHEM CO.,LTD. is a colorless or light yellow transparent liquid. Its appearance is indicative of its purity and quality, essential characteristics for consistent performance in sensitive chemical formulations. The active ingredient is the platinum complex itself, typically dispersed in a suitable carrier to achieve desired platinum concentrations.
One of the key features of Karstedt's Catalyst from NINGBO INNO PHARMCHEM CO.,LTD. is the availability of various platinum content concentrations. Recognizing that different applications require specific catalytic activity levels, we offer customizable concentrations ranging from 500 ppm up to 200,000 ppm (0.05% to 20%). This flexibility allows customers to optimize their formulations for factors such as cure speed, temperature profile, and catalyst cost.
The primary application of this high-efficiency catalyst is in catalyzing the addition type cross-linking reaction between vinyl siloxane polymers (like vinyl silicone oil or vinyl rubber) and hydrogen siloxane polymers (hydrogen silicone oil). This reaction forms a three-dimensional network structure, transforming liquid or paste silicone precursors into solid or gel elastomers or resins. This process is fundamental in the production of numerous silicone-based products.
Specific applications where Karstedt's Catalyst is extensively used include the manufacturing of:
Furthermore, the catalyst acts as an auxiliary in certain polyurethane and silicone coating formulations, enhancing properties or facilitating specific cure mechanisms. Its role in defoamers is also significant, contributing to the stability and performance of these additives.
The efficiency of Karstedt's Catalyst from NINGBO INNO PHARMCHEM CO.,LTD. is evident in its ability to promote rapid thickening or vulcanization at typical processing temperatures (e.g., 25ºC). This high reactivity ensures efficient production cycles and energy savings compared to slower curing systems.
The chemical structure of Platinum(0)-1,3-divinyl-1,1,3,3-tetramethyldisiloxane complex is key to its performance. The platinum atom is complexed with divinyltetramethyldisiloxane ligands, which stabilize the active Pt(0) species. During the hydrosilylation reaction, the vinyl and Si-H bonds interact with the platinum center, leading to the formation of a new Si-C bond and the subsequent cross-linking of the polymer chains. The precise structure and purity of the catalyst are critical for preventing side reactions, such as hydrogen evolution, which can cause bubbling or voids in the final product.
At NINGBO INNO PHARMCHEM CO.,LTD., we understand the importance of consistent quality and reliable supply for our customers' manufacturing processes. Our Karstedt's Catalyst is produced under strict quality control measures to ensure reproducible performance with every batch. We are dedicated to providing catalysts that meet the high standards required by demanding applications in the silicone and related industries.
