Research progress of high performance two-component silicone potting adhesive

With the development of industrial technology, the demand for packaging materials such as high-performance two-component silicone potting adhesives is growing, especially in the aerospace, electronic and electrical and automotive industries. Its excellent electrical insulation, thermal stability and chemical inertness make it a research hotspot. In this paper, the preparation, curing mechanism and characterization of high performance two-component silicone potting adhesives were reviewed, with emphasis on the latest progress in this field at home and abroad. Through systematic analysis and collation of the literature published in recent years, the key factors and influencing mechanism of improving the performance of two-component potting adhesives were revealed, which provided a trend for the preparation of such materials with high performance. It was found that the comprehensive properties of potting adhesives could be significantly enhanced by the addition of nano-fillers and the optimization of crosslinking density. After considering the performance and cost comprehensively, this paper puts forward the future research direction and potential application prospect of potting adhesive, hoping to provide useful reference for academic research and industrial application in related fields.
