| Abstract: | The problem of crack initiation in epoxy resin sealing compounds at low temperature is discussed in this paper. The reasons of the crack initiation are analyzed. The research development about the process and the methods to improve the crack-resistant of the epoxy resin sealing compounds by choosing suitable epoxy resin, curing agent,toughening agent and filler are also introduced in detail. Meanwhile, a series of methods are proposed to improve the crack-resistant attributes by optimizing the techniques about structure design and sealing of product. |
