In silicone rubber production, methyl hydrogen silicone fluid serves as a key crosslinking agent due to its active Si-H groups, which react with vinyl-functionalized polysiloxanes via hydrosilylation. This reaction, catalyzed by platinum complexes, forms a thermally stable, three-dimensional network.

View MoreThe silane coupling agent plays a critical role in composite resins by serving as a molecular bridge between the organic resin matrix and inorganic filler particles. Here’s a structured explanation of its functions:
View MoreThe function of a coupling agent is to act as a molecular bridge between two dissimilar materials, typically an organic matrix (e.g., polymers, resins) and an inorganic filler or substrate (e.g., glass fibers, minerals, metals). This enhances interfacial bonding and overall composite performance. Below is a structured breakdown of its key functions:
View MoreHere are key examples of silane coupling agents, categorized by their functional groups, along with their chemical structures, applications, and industrial relevance:
View MoreSilane coupling agents serve as molecular bridges between incompatible materials through their unique bifunctional structure.
View MoreModern composite engineering leverages silane coupling agents to integrate nanofillers (CNTs, graphene) with macro-scale reinforcements.
