I.Characteristics of Paper-Plastic Composite Packaging Materials Paper-Plastic Composite Packaging Materials As end-consumers increasingly demand visual impact and packaging perfection from various brands, as well as a focus on environmental sustainability, many brands are incorporating more paper elements into their packaging designs. Fruit gift boxes, snack bags, and medicine boxes all feature p...
The adhesive (glue) used in self-adhesive labels is a key factor in determining label performance, directly affecting the adhesive's adhesion, durability, and application scenarios. Different glue types are suitable for different materials, environments, and applications. This article will introduce the types and characteristics of self-adhesive label glues, as well as factors to consider when sel...
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, hydro...
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 i...
Acrylic resins used in adhesives differ from those used in coatings in the following ways: Performance Characteristics Acrylic resins used in adhesives High bond strength: They must form a strong bond between different materials and cure quickly to generate sufficient cohesive and adhesive strength. For example, α-cyanoacrylate adhesives cure in seconds, achieving fast bonding. Good flexibility: W...
I. Basic Properties of Water-Based Acrylic Resin Emulsions: Water-based acrylic resin emulsions are formed by adding acrylic monomers and solvents to a reaction tank. In the presence of an initiator and emulsifier, an emulsion is formed through an emulsion reaction. This emulsion exhibits the following basic properties: 1. High Transparency: Water-based acrylic resin emulsions are highly tran...
Fabric coating is a processing technology developed in textile finishing because it can give fabrics various functions, unique style, feel, and appearance, and increase product added value. Therefore, coated textile products are constantly emerging internationally, and their application fields are becoming increasingly wide. The low-temperature resistance, high elasticity, and high modulus of poly...
【Introduction】 In industries such as coatings, adhesives, leather finishing, and textile processing, the terms "resin," "dispersion," and "emulsion" appear frequently, often confusing newcomers. As a manufacturer with many years of experience in the waterborne polyurethane field, we understand that understanding the differences between these fundamental concepts is crucial for material s...
The following are the specific types and characteristics of water-based acrylic emulsions used in architectural coatings: 1. Odorless Acrylic Emulsion for Interior Walls: Low VOC formula, leaving walls fresh and uncluttered. 2. Weather-Resistant Acrylic Emulsion for Exterior Walls: Resists UV aging, keeping walls looking new for ten years. 3. Acrylic Emulsion for Stone Paint:&n...
Water based acrylic polymer emulsions are fully reacted acrylic polymers dispersed in water. These products contain no residual free formaldehyde. These polymers are now being widely used in the paint/coatings, ink, leather, textile and adhesives industries 1. Metal corrosion protection acrylic emulsion: Salt spray resistant and corrosion resistant, protecting metal substrates. 2. Steel structure ...
Packaging and Printing Scenarios 1. Acrylic emulsion for paper packaging bonding: Strong adhesion, environmentally friendly and odorless. 2. Acrylic emulsion for color box printing: Good adhesion, vibrant colors that don't peel off. 3. Acrylic emulsion for corrugated paper bonding: Strong water resistance, cardboard boxes are resistant to pressure and don't easily fall apa...
The following are examples of acrylic emulsion applications in textiles and special applications, along with their demonstrated characteristics and features: 1. Fabric Coating with Acrylic Emulsion: Imparts waterproof properties while maintaining breathability. 2. Nonwoven Fabric Bonding with Acrylic Emulsion: Provides strong adhesion and enhances the strength of nonwoven fabri...
In water based paint formulations, the base material is the key component that forms the paint film and determines its performance. When designing the formulation, the amount of waterborne resin should be maximized, accounting for 60-70% by volume, to ensure the highest possible content of effective film-forming agents in the paint. This guarantees a thicker, fuller paint film in a single coat. Wa...
Film-Forming Aids Polymers that make up emulsions or dispersions typically have glass transition temperatures above room temperature. To ensure good integration of emulsion particles into a uniform paint film, film-forming aids must be used to lower the minimum film-forming temperature (MFFT). Film-forming aids are a class of small-molecule organic compounds that eventually escape and volatilize f...
In many applications, acrylic adhesives do not require the addition of tackifying resins to improve pressure sensitivity, but in most cases, they are necessary: To increase initial tack and peel strength To improve adhesion to low surface energy materials Tackifying resins are commonly used in acrylic emulsion systems, such as paper labels and packaging tapes. They improve peel strength on difficu...
In the printing industry, the demands for waterborne coating performance, especially high-gloss applications, are increasingly stringent. Single-component waterborne acrylic emulsion systems often suffer from limitations in balancing key performance characteristics when meeting high-end requirements. To address this, Sinograce Chemical has developed a high-performance emulsion combinatio...
