Glove PU coating refers to coating the outer layer of gloves with a layer of polyurethane (PU) material. This coating has a variety of functions, mainly including: Oil and chemical resistance: makes the gloves suitable for work environments where oils and chemicals need to be handled. Anti-slip and wear resistance: Enhances the stability of the gloves in wet or greasy environments, reduces the ris...
01 Conditions for film formation Stowing operation The water evaporates, and the particles are close to each other to achieve a dense charging state Fusion process The surface layer of the particles is destroyed, and the particles are in contact with each other. Diffusion process The molecular chains between the dispersion particles are diffused with each other to form a homogeneous film with cert...
The application of water-based ink coating is very wide, mainly reflected in the following aspects: 1.Printing industry Water-based inks can be used to print a variety of paper and packaging materials, such as books, newspapers, magazines, posters, gift boxes, etc. All kinds of paper such as kraft paper, coated paper, thermal paper, Glasin paper, release paper and corrugated board can be...
(1) The use of hydrosol Hydrosol is a polymeric dispersion of very small particles, which has the characteristics of both emulsion system and solution system, and can effectively improve water resistance (2) Reduce the amount of emulsifier Although emulsifier plays an important role in the formation of micelles in polymerization and the stability of the polymerization emulsion, it is als...
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...

1. Molecular structure The basic structure of acrylic resin contains a large number of carboxylic acid groups, and it is copolymerized with other monomers. This structure determines that the acrylic resin has a high cross-linking density and strength, which can effectively prevent the penetration and corrosion of chemical substances. 2. Physical properties Acrylic resin has excellent wea...
Leather finishing is generally divided into bottom coating, middle coating and top coating three parts. The bottom coating requires strong adhesion, hiding power, good embossing formability and stereotyping, and the middle coating further covers and corrects the color, and finally achieves the visual and physical performance requirements through the top coating. With a specific top coat, the effec...
The main function of the film surface coating treatment agent is to enhance the comprehensive performance of the film through chemical or physical modification. The specific functions can be summarized as follows: 1.Enhance surface adhesion Improve the adhesion of ink/adhesive: By increasing the surface energy of the film or introducing polar groups, make the ink, coating or adhesive more lik...
