Hydrophobic additives
Our range of hydrophobic additives are based on a number of chemistries including stearate, silicone and silane with options to match your formulation, performance and budgetary needs. With a variety of high-performing products, you can benefit from using lower doses, enhancing your end-product while controlling costs.
