Product Description

Silica sol

The Main Description

Silica sol is a member of the comprehensive papermaking performance solution. It is typically used in conjunction with cationic coagulants and high-molecular-weight flocculants to maximize retention, drainage, paper strength, and uniformity.

The Main Application
Silica sol is specifically designed to enhance retention and drainage of alkaline and acidic coated board papers, bleached board papers, corrugating medium papers, groundwood pulps, and wood-free cultural paper systems.
Product Advantages

• Maximizes retention in both alkaline and acidic systems
• Improves moisture removal by reducing headbox and whitewater tray solids, thereby enhancing pressing and drying efficiency
• Enhances paper quality through reduced two-sidedness, improved formation, and increased strength
• Optimizes optical properties and printability via uniform distribution of fillers and fines in the sheet
• Reduces fiber costs by enabling higher filler addition due to improved fine particle retention in acidic/alkaline systems
• Lowers wet-end additive consumption (e.g., wet strength agents, clay, dry strength agents, sizing agents, starch, defoamers, dyes) through improved first-pass retention
• Minimizes sewer losses and reduces effluent treatment costs by retaining first-pass fibers and fillers

Storage
The product is unstable below 0°C and should be protected from freezing.
The shelf life is 6 months.
