Tetrabutanone oxime based silane is a solid at room temperature, and mixed de oxime type crosslinking agents belong to the mixed solution products of tetrabutanone oxime based silane. When the temperature is low, due to solubility issues, tetrabutanone oxime based silane will precipitate in powder form.

The phenomenon of precipitation of tetrabutanone oxime based silane occurs in the mixed deioxime crosslinking agent, and it must be heated to dissolve the tetrabutanone oxime based silane before use.
