Product Description

water based solid acrylic resin for pigment grinding 
Water based acrylic resin

Water-based acrylic resins are widely used in various applications, including pigment grinding, ink formulation, and overprint varnishes (OPV).
These resins are preferred due to their environmental friendliness, low VOC (volatile organic compound) content,
and excellent performance properties.

Advantages of Water Based Acrylic Resins

• Environmentally friendly (low VOC, non-toxic).

• Easy to clean up with water.

• Good compatibility with other water-based systems.

• Versatile for a wide range of applications.

1. Pigment Grinding

Water-based acrylic resins act as dispersants and stabilizers during pigment grinding. They help in:

• Wetting and dispersing pigments: The resin reduces the surface tension, allowing pigments to be evenly dispersed in water.

• Stabilizing the dispersion: Prevents pigment re-agglomeration, ensuring a stable and uniform pigment paste.

• Compatibility: Works well with a wide range of pigments, including organic and inorganic types.

Key Properties for Pigment Grinding:

• High molecular weight for effective stabilization.

• Good wetting and dispersing capabilities.

• Low foam generation during grinding.

2. Ink Formulation

Water-based acrylic resins are used in the formulation of water-based inks for packaging, textiles, and printing.
They provide:

• Adhesion: Excellent adhesion to various substrates like paper, plastic, and metal.

• Flexibility: Good film flexibility, which is essential for applications like flexible packaging.

• Durability: Resistance to water, abrasion, and chemicals.

• Gloss and clarity: High transparency and gloss for vibrant ink colors.

Key Properties for Inks:

• Fast drying time.

• Good pigment binding capacity.

• Compatibility with other ink additives (e.g., defoamers, surfactants).

 

3. Overprint Varnish (OPV)

Water-based acrylic resins are used in OPVs to provide a protective and decorative layer on printed surfaces.
They offer:

• Gloss or matte finish: Depending on the formulation, they can provide high gloss or matte effects.

• Scratch and scuff resistance: Protects the printed surface from damage.

• Water and chemical resistance: Enhances durability in demanding environments.

• Low odor and eco-friendliness: Ideal for food packaging and other sensitive applications.

Key Properties for OPV:

• Excellent film-forming properties.

• Good adhesion to printed surfaces.

• Resistance to yellowing and aging.
