The invention relates to a method for cutting the monocrystalline silicon rubber modified epoxy resin and its raw material comprises the following components: the A component is epoxy resin 35~78%, 20~60%, toughening agent, defoaming agent 0.5~2%, coupling agent 0.5~3%; B component for polymerization of mercaptan 48~69%, modified alicyclic amine 30~50%, accelerator 1~5%. The modified epoxy resin has good degumming property and can reduce the rate of chip loss. The epoxy resin has been used to impart the toughness and temperature resistance of the alicyclic amine material, and the surface tension of the system is given, so that the overall flow performance of the system is improved during the coating process. At the same time, the silane bond can hydrolyze the hydroxyl groups on the surface of the glass and silicon wafer to improve the adhesion of the glass surface and the silicon wafer surface. In addition, through the system and water toughening modified alicyclic amine system in the increased temperature resistance TG decreased the off chip phenomenon does not exist in the cutting and flushing process, in the process of heating to 40~50 Deg. C, can rapid degumming softening in high water and heated state. The modified epoxy resin of the invention is applied to the cutting of monocrystalline silicon rods, and plays an important role in the monocrystalline silicon sheet industry.
