Maximum alkalinity per kilogram.
Anhydrous sodium metasilicate contains no water of hydration, so it delivers the highest active alkalinity of the metasilicate range. That makes it the grade of choice for concentrated products where every kilogram of packed material must carry cleaning power rather than water.
It is widely used in heavy-duty degreasing compounds, metal pre-treatment before coating, and industrial cleaning powders that must remain dry and free-flowing through long storage.
Highest active alkalinity
No bound water, so more available alkali per unit weight.
Concentrated formulations
Allows high-strength blends with reduced pack size.
Low moisture
Stays dry and stable in sealed storage.
Reduced freight cost
Less water shipped per tonne of active material.
