TOS is solid at room temperature. Mixed oxime cross-linking agents are all mixed solution products of TOS. When the temperature is low, due to solubility problems, TOS will precipitate in powder form. 

Mixed deoximation cross-linking agents may cause precipitation of TOS, which must be heated to dissolve the TOS before use.
