No. The use of peroxides or azo compounds as free radical initiators is recommended only to promote vinyl crosslinking (cure) at relatively low temperatures. Technical Bulletin 1 (TB1) on this website gives temperature / time curves for several recommended peroxides. Without the use of a free radical initiator such as a peroxide or azo compound, Ceraset Polysilazane 20 or Ceraset Polyureasilazane will undergo vinyl crosslinking at temperatures of about 180°-200° C.
