What is a Reactive Gel Catalyst?

A reactive gel catalyst (RGC) is a type of catalyst that combines the properties of a gel and a catalyst. It is designed to facilitate chemical reactions while maintaining a stable structure under extreme temperatures. The "reactive" part refers to its ability to participate in or accelerate chemical reactions, while the "gel" component gives it a unique physical form that enhances its performance in various applications.

Key Characteristics of RGCs

Thermal Stability: RGCs can withstand temperatures ranging from -200°C to 1,000°C, depending on the specific formulation.
Mechanical Strength: They retain their structural integrity even under high pressure and mechanical stress.
Chemical Reactivity: RGCs can catalyze a wide range of reactions, including polymerization, cross-linking, and decomposition.
Viscosity Control: The gel-like consistency allows for easy application and uniform distribution in complex geometries.
Customizability: RGCs can be tailored to meet the specific needs of different industries, such as aerospace, automotive, and energy.

How Does an RGC Work?

At its core, an RGC works by providing a stable platform for chemical reactions to occur.
