Solid Acrylate Resin for Ink and Opv

The main functions of solid acrylic resins in water-based inks and OPV include providing pigment dispersion, improving ink performance and enhancing adhesion.

Solid resins are usually used as pigment dispersants in water-based inks, which can improve the dispersion and color development of pigments in inks, thereby improving the film-forming properties and printing effects of inks. In addition, solid acrylic resins can also improve the fluidity, wettability and drying properties of inks, ensuring that the inks perform well during the printing process.

Specific ingredients and mechanisms of action Solid resins in water-based inks are mostly alkali-soluble acrylic resins, whose main components include acrylic acid or methacrylic acid. When dissolved in alkali, they will form macromolecular surfactants with emulsifying, wetting and dispersing functions. This resin has excellent adhesion to a variety of low-polarity substrates such as PE film, PP film and aluminized film.

The molecular weight, distribution, acid value and glass transition temperature of solid resins will also affect their performance in inks. For example, resins with higher glass transition temperatures have higher hardness and weather resistance, but harder film formation; while resins with lower glass transition temperatures have softer film formation and are easy to adhere.

Water-based inks are widely used in packaging printing, label printing, and publishing printing. Due to its environmentally friendly characteristics, water-based inks are increasingly used in food packaging and children's products. The use of solid resins in water-based inks not only improves the performance of inks, but also enhances the adaptability of inks to different substrates, thereby broadening the application range of water-based inks.
