Silicas for Paper Applications

Grace Davison Engineered Materials offers various silica materials for specific applications in the paper industry:

• Colloidal silica dispersions as a nano particle retention aid in the wet end
• Sodium aluminum silicate as functional filler in the paper machine wet end
• Micronized silica gel in specialty papers, for example in the coating of thermal and other specialty printing papers to improve absorption properties
• Colloidal silica and the coarser micronized silica gel as a frictionizer in packaging and other paper grades like grinding papers to enhance anti-slip characteristics
• Colloidal silicas for surface treatment to improve the gloss and printability of uncoated papers
