In ink formulation systems, performance is typically achieved through the synergistic action of multiple materials.

With deep expertise in independent R&D of nano-silica materials, LINGWEI has gradually built a product matrix spanning from functional fillers to film-forming resins tailored for ink application scenarios. This matrix covers multiple key levels of ink formulation:

• Matting agents and adsorbents address surface effects and imaging quality
• Silica sol optimizes coating density and interfacial performance
• Waterborne acrylic resin provides the foundational assurance for film formation, adhesion, and durability

Specialty Silica for Printing Ink Systems

As printing ink technology continues to innovate, LINGWEI provides comprehensive specialty silica solutions for printing ink systems to meet higher standards and emerging application demands.

• Excellent printability and compatibility: Suitable for letterpress, gravure, offset, screen printing, and various other printing processes
• Superb matting performance and high transparency: Uniformly dispersed in ink films to achieve a fine matte effect while maintaining high coating transparency without affecting ink color performance
• Outstanding anti-blocking and slip properties: Effectively prevents blocking during stacking of printed materials and improves post-press processing performance
• Easy addition and dispersion: Good dispersibility in ink systems, facilitating matte level adjustment with excellent storage stability
• Recommended models: A350-I, HS417-1, and others

HOMJET® Specialty Silica for Inkjet Paper Coating

HOMJET® is a transparent surface treatment adsorbent used in top and bottom imaging precoat formulations for paper, fabric, PP, PVC, PET and other substrates, effectively improving ink absorption and print quality for both gloss and matte coatings.

• High ink absorption: Provides efficient adsorption for inkjet coatings, rapidly absorbing water from ink to prevent dye diffusion or bleed-through, ensuring smooth imaging with sharp edges
• Excellent coating appearance: Uniform particle distribution and superior dispersion help reduce fisheyes and craters on the coating surface, significantly improving coating smoothness and slip properties
• Exceptional transparency: Clearly presents color vibrancy, saturation, resolution, and layering
• Recommended models: SA580, TSA580, and others

HOMSOL® Specialty Silica Sol for Water-Based Ink / Inkjet Media

• High gloss and transparency: Improves gloss level of cast-coated high-gloss inkjet papers and other media without sacrificing coating transparency, delivering vivid image colors
• Compatibility and colloidal stability: Multiple particle sizes and surface modification options to adapt to different resin systems and ensure formulation stability
• Enhanced surface strength and scratch resistance: Improves coating hardness and abrasion resistance
• Increased surface friction coefficient: Applied to paper, board, and film coatings to improve paper feeding stability and prevent slipping and roll blocking
• Improved inorganic pigment dispersion: Optimizes pigment wetting to enhance dispersion stability during ink storage and printing
• Recommended model: LJ1530A and others

POLYCOAT® Specialty Acrylic Resin for Water-Based Inks

In ink formulations, film-forming resin is the core carrier that determines basic coating performance. LINGWE's POLYCOAT® specialty acrylic resin series for water-based inks, optimized through molecular structure design and formulation validation, helps ink manufacturers improve product performance in adhesion, durability, and printability. The company offers waterborne acrylic emulsions and alcohol-water acrylic resins covering key gravure printing scenarios including surface printing, reverse printing, primer coating, and resin modification.
