Ink resin is the pigment carrier in the ink, is the core material of the ink, its quality is good or bad, will directly affect the performance of the ink, because the connection material to a large extent determines the viscosity of the ink, viscosity, dryness, fluidity and other properties. Color fastness The adhesion between the ink and the substrate mainly includes the chemical bond force ...
1.There are many formulations of coated glue, and different formulations need to be determined according to the specific use. It generally includes basic glue, thickener, curing agent, auxiliaries and other ingredients. 2.Basic glue is the most important component of laminating glue, it can be selected according to different use requirements of different types, such as water-based, oily, dilu...
The transparency of composite film is very high, but in the composite processing of plastic film, the composite film often has problems such as insufficient transparency. So, what is the reason for affecting the transparency of the composite film? This article analyzes one by one for reference. Improper selection of adhesives: Such as the color of the adhesive itself is dark or the fluid...
Different processing methods will cause different fault manifestations, the following we mainly analyze the causes of paper thermit sealing delamination phenomenon under the gravure and solvent-free composite processing methods. The YBB paper aluminum-plastic composite film standard does not specify the composite strength index of the paper aluminum layer in the paper aluminum-plastic composite fi...
The high adhesion base coating improves the adhesion of the inkjet coating on PP paper Prevent ink from penetrating into PP composite paper substrate Fast drying speed to meet the needs of production line Good weather resistance, no yellowing Easy to use, safe and environmentally friendly Anhui sinograce company's PP composite paper digital inkjet coating adhesive base | Inkblot coating base ...
Classification of surfactant applications in coatings: According to the role of the classification, the coating industry used surfactants can be divided into the following categories: emulsifier, pigment surface treatment agent, pigment wetting dispersant, defoamer, levelling agent, anti-mold, fungicide, antistatic agent, brightening agent, slippery agent and so on. Application of surfac...
Insufficient or uneven amount of glue due to insufficient amount of glue produced by the white spot can be observed in the composite machine. In the dry composite process, the coated adhesive must be able to fill the bumps and bumps on the surface of the ink and film to avoid appearance defects such as obvious white spots. When the water-based adhesive dry composite is used to produce lightweight ...
Due to the hydrophobic properties of waterborne polyurethane resin, it is difficult to dissolve in water or disperse uniformly, and the high reactivity of isocyanate groups to water, the direct synthesis of waterborne polyurethane faces many challenges. Therefore, to achieve the preparation of waterborne polyurethane, the primary strategy is to cleverly integrate hydrophilic functional groups (suc...
Paper aluminum-plastic composite film in the actual application of medical packaging powder, granule packaging products compared to the plastic aluminum-plastic packaging commonly used in the market now has the following advantages: (1)The mechanical strength of the paper is high, the rigidity is good, and the ability to maintain the bag after forming is strong, which improves the cleanliness of t...
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...
water base varnish for glass Does not contain benzene, esters and other harmful solvents, does not contain free TDI, does not burn, is the latest environmental protection glass process paint, by the international and other authoritative verification institutions assessed as the real green environmental protection products. Solve problems It is required to blister at 75℃ for 30 minutes and it is re...
(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...
Water-based viscosification emulsion plays a very important role in water-based acrylic pressure sensitive adhesive, which can improve the adhesion strength and initial viscosity of pressure sensitive adhesive on high and low energy surface, so as to achieve the best balance point, and improve the application range and grade of pressure sensitive products. Today, I will introduce you to the applic...
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...
The characteristics of paper varnish mainly include the following aspects: Fast curing speed The curing speed of paper varnish is extremely fast. Especially when using UV technology, the curing process can be completed within a few seconds to a few minutes, making it suitable for high-speed printing and multi-color printing. Excellent environmental protection performance Many modern paper varnish ...
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...
