LOW EXPANSION CEMENT 29

Sauereisen Low Expansion Cement No. 29 is an inorganic cement used for embedding heating elements, insulating thermocouples, coating resistors and coils, and mechanically sealing parts where high resistance to electricity, chemicals and thermal shock is required. A strong resistance to cryogenic conditions makes No. 29 a common product for aerospace applications. No. 29 adheres to glass, porcelain, ceramics, metals and other surfaces.
