Resins for Inkjet Inks
Resins for Inkjet Inks
The HIROS-X™ Series resins can be used in inkjet inks for pigment dispersion, binding, and primer applications.
Available in various polymer types including styrene-acrylic, acrylic, and styrene-maleic acid resins, providing a wide range of performance properties.
Characteristics
- Products designed for pigment dispersion provide excellent dispersibility, storage stability, and gloss performance.
- Products for binders offer excellent alcohol resistance, scratch resistance, and adhesion to substrates.
- Primer grades are also available for pre-coating applications to enhance ink adhesion to substrates.
Solid resin
- Synthesized via solution polymerization.
- Suitable for pigment dispersant applications.
- Offers favorable pigment dispersion, binding, and gloss.
