9727 Product parameters of catalyst
9727 Catalyst is a highly efficient polyurethane catalyst based on organotin compounds, with its main component being Dibutyltin Dilaurate (DBTDL). This catalyst has the following distinctive features:
1. Chemical composition and structure
9727 The main active ingredient of the catalyst is DBTDL, and its molecular formula is C36H70O4Sn. DBTDL is a bifunctional catalyst that can not only promote the reaction between isocyanate (NCO) and polyol (Polyol, OH), but also accelerate the generation of carbon dioxide (CO2), thereby effectively controlling the foaming process. In addition, the 9727 catalyst also contains a small amount of solvent and additives to improve its stability and dispersion.
2. Physical properties
The physical properties of the 9727 catalyst are shown in Table 1:
