What are the differences between polyurethane water-based ink and acrylic water-based ink
Date: Jul 18 2023 From: Star Color
Polyurethane water-based ink and acrylic water-based ink are both types of water-based inks used in various applications such as screen printing, fabric printing, and art projects. While they share similarities, there are distinct differences between the two:
1.Composition:
Polyurethane water-based ink: Polyurethane ink consists of polyurethane resin as the main binder. It is a type of plastic-based ink that provides durability and flexibility. Polyurethane inks often contain additives such as pigments, fillers, and cross-linking agents.
Acrylic water-based ink: Acrylic ink, on the other hand, utilizes acrylic resin as the primary binder. Acrylic resin is derived from acrylic acid and provides excellent adhesion and color retention. Acrylic inks also contain pigments and additives to enhance their properties.
2.Application:
Polyurethane water-based ink: Polyurethane inks are commonly used in applications that require high durability and elasticity. They are often used for printing on fabrics, including garments, sportswear, and other textile products. Polyurethane ink offers good resistance to washing and abrasion.
Acrylic water-based ink: Acrylic inks are versatile and can be used on various surfaces, including paper, cardboard, wood, and fabrics. They are frequently used in screen printing, as well as in art and craft projects. Acrylic ink provides excellent color vibrancy and can be used for both detailed work and large areas.
3.Performance:
Polyurethane water-based ink: Polyurethane ink forms a strong bond with the fabric fibers, resulting in excellent wash fastness and resistance to cracking or peeling. It maintains its flexibility even after multiple washes and can withstand stretching and bending without cracking.
Acrylic water-based ink: Acrylic ink also offers good durability and adhesion, but it may not be as flexible as polyurethane ink. While acrylic ink is generally suitable for fabrics, it may not provide the same level of resistance to washing and stretching as polyurethane ink.
4.Environmental Considerations:
Polyurethane water-based ink: Polyurethane ink typically contains a higher amount of synthetic chemicals compared to acrylic ink. It may require additional care during disposal and may have different environmental impact considerations.
Acrylic water-based ink: Acrylic ink is generally considered more environmentally friendly. Acrylic resins are water-soluble and non-toxic, making them safer for both users and the environment. They often comply with environmental regulations and can be cleaned up easily with water.
It's important to note that specific formulations of polyurethane and acrylic inks can vary among manufacturers, and the performance characteristics may differ accordingly. It's recommended to follow the instructions provided by the ink manufacturer for optimal results and to choose the ink that best suits your specific application requirements.
