Polysiloxaneurethanes (PSUR) are block copolymers containing polysiloxane and urethane (or polyurethane) segments and showing very interesting mechanical, dielectric and surface related properties. Brief reviews of investigations that have been carried out so far on PSUR are presented with special reference to coating applications of them. The properties of the novel moisture-curable PSUR (MCPSUR), tested before and after moisture curing, are discussed in connection with their chemistry and structure. The properties of aqueous dispersions of PSUR (ADPSUR) synthesised in ICRI are also reviewed. The preliminary results of some coating tests made for MCPSUR and ADPSUR are presented.
