Abstract

The invention provides a room temperature curing adhesive which contains a hydroxyl-terminated dialkyl siloxane polymer, a silane cross-linking agent, a catalyst and water. The hydroxyl-terminated dialkyl siloxane polymer, the silane cross-linking agent, the catalyst and the water are divided into at least two independent parts, wherein one independent part comprises the catalyst and the water, but do not contain the hydroxyl-terminated dialkyl siloxane polymer or the silane cross-linking agent. The room temperature curing adhesive has the advantages of high curing speed, and can be used in the assembly of the solar cell composite board and the electronic module and all the assembly industries with relatively high requirements on the room-temperature curing speed.

Description

technical field [0001] The invention relates to a room temperature curing adhesive and its application. Background technique [0002] Room temperature curing (RTV) glue, with its unique weather resistance and aging resistance, has become one of the indispensable materials in the solar cell assembly industry. It is used between the metal frame of the solar panel and the main material to keep the edge of the panel away from water. Currently disclosed room temperature curing adhesives include single-component curing adhesives and two-component curing adhesives. The products of single-component curing adhesives include: Kesaixin 1527 of Beijing Tianshan New Material Co., Ltd., 7091 of Dow Corning, KE45 of Japan’s Shin-Etsu, and 960 of Shanghai Huitian Chemical New Material Co., Ltd., etc. Their basic characteristics are: one-component , room temperature curing, good sealing, good adhesion with the substrate, and long-term material stability. However, the problem with this typ...
