AL151 is a clear, colorless, strongly alkaline liquid with smell and being very sensitive to hydrolysis. The chloride content ranges in the lower ppm-level. AL151 is used as adhesion promoter at organic/inorganic interfaces, for modification of surfaces (corrosion prevention, component of primers) or as a moisture crosslinker of silicone polymers. The application as “coupling agent” leads in general to an improvement of mechanical and electrical product properties above all under exposure to heat and/or moisture.

- Solubility
AL151 is unlimited miscible with water with spontaneous hydrolysis occurring. Caution: Due to solution enthalpies mixing water is exothermic. Always stir AL151 into water. With alcohols miscibility is, in general, possible with self-catalyzed exchange of the alkoxy-groups. In aliphatic and aromatic hydrocarbons and (moisture-free!) ethers or esters AL151 is easily soluble at differing levels. With ketones and various halogenated compounds a slow reaction can occur.
