Removable labels feature low peel force and can be removed cleanly from the surface after a period of time without contamination. These require a low-tack adhesive that can be removed without residue after rigorous aging. Currently, a widely adopted low-cost removable adhesive design involves adding a small amount of crosslinking agent to a general-purpose low-tack pressure-sensitive adhesive to increase its molecular weight and reduce its tack. However, this design does not alter the polarity or microstructure of the pressure-sensitive adhesive, resulting in only a short period of removability. After exposure to high temperature and humidity or after a certain period of storage, pressure-sensitive adhesives may still fully wet the substrate, exhibiting permanent adhesive properties and making them difficult to completely remove. Sinograce Chemical's removable label adhesive offers three key performance advantages: peel force, removability, and substrate adhesion. Removability Removable pressure-sensitive adhesives exhibit a wide range of removable properties on various surfaces. Surface adhesion Surface adhesion is a key property of removable pressure-sensitive adhesives. They exhibit excellent adhesion to paper substrates. For film-based surface materials, a suitable surface treatment (such as double-layer coating) is required to achieve good adhesion. Applications Various single copper, mirror copper, mirror wet-strength paper, thermal paper, mirror aluminum paper, aluminum foil labels, and advertising materials.

In label production, whether choosing oil-based, water-based, or hot melt, sufficient initial tack is required. Adhesives with strong initial tack properties can easily adhere to a variety of surfaces. So, what are the advantages of using hot melt adhesive in this regard? 01 Environmental Protection Currently, the hot melt adhesives used in labels, which are common in our daily lives, have a solids content of up to 100%, producing no solid waste during use and meeting modern environmental standards. With the development of this type of hot melt adhesive, many countries have switched from oil-based adhesives to water-based and hot melt adhesives for label production. 02 Strong Adhesion Water-based adhesives have advantages in label production, including a wide temperature range and smoothness. However, initial tack and peel strength are not very strong, and they may lack sufficient adhesion to non-polar surfaces. Hot melt adhesives, on the other hand, have very strong initial tack and peel strength, meeting the bonding requirements of a wide range of materials. 03 Low Cost In fact, water-based adhesives generally have a solids content of around 50%. When the coating area is uniform, the amount of hot melt adhesive used can be significantly reduced. Hot melt adhesive does not contain water or other solvents, so it does not require drying during production; it simply cools and solidifies naturally, saving significant time, improving production efficiency, and reducing costs. Compared to water-based and oil-based adhesives, hot melt adhesive offers advantages such as stronger adhesion, environmental friendliness, non-toxicity, the need for drying equipment, small footprint, fast production speed, and low cost. Therefore, hot melt adhesive is rapidly developing in the label industry. Anhui Sinograce Chemical Co., Ltd. specializes in hot melt adhesives and water-based adhesives for label applications. We look forward to your purchase.

Water-based inks are primarily composed of a uniform slurry of binders, pigments, and additives. The binder is a core component of water-based inks. It not only disperses the pigment but also plays a key role in influencing ink performance, determining adhesion, water and scrub resistance, and solvent resistance. Three common types of binders for water-based inks exist: water-soluble resins, hydrosol resins, and water-dispersible resins. These resins differ in their properties and are often combined in ink formulation. While water-soluble resins dissolve in water, they have poor water resistance. Water-based inks prepared with these resins cannot be used in environments where they come into direct contact with water, limiting their use. Therefore, water-soluble resins cannot be used as the primary binder for water-based inks. Due to their low molecular weight, small particle size, and excellent uniformity, they are primarily used to adjust the viscosity and flowability of water-based inks and to disperse pigments. Hydrosol resins are prepared by neutralizing an acidic resin with a low-molecular-weight amine to form a salt, generating hydrophilic groups. These resins, also known as alkali-soluble resins, offer rapid drying and film-forming properties. Resins in this category include shellac, urethane resins, water-based amino resins, and water-soluble acrylic resins. Water-dispersible resins, also known as emulsion resins, are water-based binders that provide good dilution, fast drying, and excellent water resistance. The low viscosity and high solids content of the emulsions allow for the formation of high-performance coatings. However, water-based inks formulated with emulsion resins suffer from poor resolubility and difficulty in cleaning. Water-based printing ink formulations typically consist of an acrylate copolymer emulsion, a solid acrylic resin, a pigment, a wetting agent, and a defoaming agent. The acrylate copolymer emulsion serves as the primary binder, while the solid acrylic resin serves as the pigment dispersant, also known as a dispersing resin. The solid acrylic resins used are mostly alkali-soluble, containing approximately 30% acrylic acid or methacrylic acid. When exposed to alkali, they dissolve and immediately convert into macromolecular surfactants with emulsifying, wetting, and dispersing properties. They exhibit excellent adhesion to a variety of low-polarity substrates, such as PE film, PP film, and aluminum-coated films. Therefore, solid acrylic resin is an important functional additive in the entire water-based ink preparation process. It is not only used in large quantities in the preparation of emulsion binders, but also in considerable amounts in the ink formulation process. Another major function of water-based solid acrylic resin is to provide dispersibility for a variety of difficult-to-disperse pigments, improving color development and film-forming properties. Therefore, in the field of water-based brush ink...
