First, what is the adhesion of resin Resin adhesion refers to the ability of the resin coating to adhere to the substrate. Insufficient adhesion of the resin on the surface can cause it to fall off or foam, and affect the service life and performance of the product. Second, how to effectively improve the adhesion of resin 1. Surface treatment Surface treatment is an effective method to improv...
As for the performance difference between water-based acrylic acid and water-based polyurethane, it can be briefly analyzed from the following aspects: 1.Chemical structure: Waterborne acrylic resin is mainly composed of acrylic monomer, while waterborne polyurethane resin is composed of isocyanate monomer and polyether or polyester polymer. 2.Performance characteristics: Water-based acrylic resin...
Water-based adhesives for more sustainable bonding Water-based adhesives are an excellent alternative to solvent-based systems because they do not contain any volatile organic compounds (VOCs), are lighter in weight, and generally require less product to form a lasting bond. Compared to other solutions, water-based adhesive systems are environmentally friendly, have low VOC content and are more us...
Particle size and hydrolysis resistance: The stability of the emulsion is closely related to the particle size and hydrolysis resistance of the polyurethane particles. The smaller the particle size, the better the stability of the emulsion. The poor hydrolysis resistance will cause the emulsion to degrade slowly during the storage process, produce carboxyl group, reduce pH value, and make the emul...

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...
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 solid...
01. In the textile industry, fabric coating finishing technology is one of the important processes for improving fabric performance and expanding its application range. Waterborne polyurethane (WPU), with its excellent film-forming properties, good flexibility, and stable chemical characteristics, is gradually becoming one of the core materials in this field. This article will systematically intro...
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...
The process of coating metal with polyurethane emulsion can be divided into the following steps: Surface Preparation: Before applying the polyurethane emulsion, the metal surface needs to be properly prepared. This typically includes cleaning the surface, removing oil, dust, and other impurities, and performing rust removal to ensure coating adhesion and durability. Rust removal can be done mechan...
Waterborne coatings, including waterborne wood coatings, are coatings that use water as the dispersion medium and diluent. Unlike less commonly used solvent-based coatings, their formulation systems are much more complex. Formulation design requires attention not only to the type of polymer, the properties of the emulsion and dispersion, but also to the rational selection of various additives and ...
