BASF JONCRYL 678 Acrylic Resin

BASF JONCRYL 678 from BASF's JONCRYL series general-purpose water-based acrylic resin range for printing inks is a medium-molecular-weight solid alkali-soluble styrene-acrylic resin developed for water-based inks, pigment dispersion and overprint varnish systems. With amine as neutralizer, no cosolvent is needed in preparation, enabling low VOC (1.3%wt)

Features Of BASF JONCRYL 678 Acrylic Resin

  1. Low-VOC environmental advantage - No cosolvent needed in preparation, VOC content as low as 1.3%wt, meeting strict environmental printing standards, suitable for sensitive fields such as food packaging.

  2. Outstanding optical and film-forming performance - High gloss and excellent transparency, high hardness and strong scratch resistance after film formation, improving decorative texture and durability of end products.

  3. Efficient processing adaptability - Low solution viscosity, enabling preparation of high-solid-content systems, convenient construction and fast drying, significantly improving printing production efficiency.

  4. Broad compatibility - Good compatibility with most acrylic resins, and can also be used as protective colloid for styrene-acrylic emulsions, with wide formula adaptability.

Typical Applications Of BASF JONCRYL 678 Acrylic Resin

  1. Water-based flexographic printing ink: Flexographic printing for paper and cardboard packaging, strong color expression, environmental and low-odor, suitable for mass production.

  2. Water-based gravure printing ink: Gravure printing for plastic films and paper packaging, strong adhesion, full gloss and excellent weather resistance.

  3. Printing overprint varnish: Overprinting for various printed products, improving gloss and wear resistance, ensuring surface texture.

  4. Pigment dispersion paste: Preparation of inorganic and organic pigment dispersion pastes, improving paste stability and color development, suitable for various printing systems.
