Metal surfaces are first cleaned before being processed. Cleaning with alkaline solutions is the oldest form of commercial metal cleaning and still the most widely used. Our granulated sodium metasilicates are especially suitable for metal surface cleaning. Their granular, free-flowing property makes them very convenient for dry mixing with other cleaning agents such as phosphates, soda ash or caustic soda. Their is a choice of three different grades of metasilicate: anhydrous, pentahydrate and nonahydrate, each of which differs in terms of concentration.
For those who prefer to work with liquids, SILMACO offers a complete portfolio of alkaline sodium silicates.
