| Abstract: | The paper is related to a alkoxy-functional one-component RTV sealant which is a novel kind of environmental friendly,non-corrosive and tin-free sealant. In this work,the effects of filler, crosslinker and adhesion promoter on the viscosity, physic-mechanic properties, curing character, adhesion property and storage stability are discussed in detail. Through the formula optimization, the resulted sealant has low viscosity,excellent mechanical properties, short tack-free time, deep-section curing and good storage stability.It is currently widely used in the LCM module assembly industry. |
