Enhance the adhesion of UV ink and UV varnish on paper products! The tape won't come off Fast drying speed to meet the needs of production line Good affinity with UV varnish and UV ink Excellent strength and toughness Water-based UV base oil for high adhesion paper products Anhui Sinograce Chemical waterborne UV primer for high adhesion paper products is a high-performance waterborne coa...
Waterborne polyurethane (WPU) is a water-based dispersion material, and its unique low viscosity characteristics often bring construction challenges such as flow hanging and penetration. In order to solve these problems and improve its construction performance, self-leveling performance and storage stability, the addition of thickener has become a key step. The thickener not only endows the water-...
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 ...
The final state of waterborne polyurethane is a solid film. During the process from emulsion to solid film, accompanied by the evaporation of water and the concentration of water dispersion, the latex particles are close to each other. Before the solid content reaches 74%, the dispersion particles can move in the continuous phase of water. Under the influence of water/air interfacial tension, the ...
The viscosity of waterborne polyurethane emulsion has different distribution range, and the viscosity of waterborne polyurethane emulsion has different requirements when applied in different fields. In addition to adjusting the viscosity by adding thickening agents, it can also affect the viscosity of waterborne polyurethane emulsion from the molecular structure, including the content of hydrophil...
Most coatings are composed of a base material (one or more resin mixtures), pigments (including physical pigments and functional pigments), solvents and some small amounts of additives and other coating raw materials. In the production of coatings, after the selection of various coating raw materials necessary for coating components, the next is how to make reasonable use of the technical and econ...
There are several main reasons for water-based emulsion breaking: 1.Large temperature changes, water-based emulsion is easy to separate into water phase and oil phase at high temperature, and easy to crystallize at low temperature. 2.The selection of emulsifier is improper, and the type and dosage of emulsifier are different, which has a great impact on the stability of emulsification. The choice ...
The main reason for water-based ink drying 1.Water-based ink: water-based carton ink, non-woven ink, paper towels, paper cups and paper bags and other packaging printing; 2.Water-based polishing oil series: water-based polishing oil, polishing oil, high gloss, wear-resistant, matte, waterproof, antifreeze and other environmental protection water-based products. Water-based ink drying is mainly cau...
First, resin reaction temperature standard The reaction temperature of resin is an important process parameter, which has great influence on the reaction rate, physical properties and chemical stability of resin. In general, the resin reaction temperature should be determined according to different resin types and catalyst types. The following are some commonly used resin reaction temperature stan...
Flexo is a flexible, high resolution, warped letterpress plate. In recent years, flexo printing has developed rapidly in the field of printing, and its development prospects are generally optimistic. Flexographic printing presses transfer the right amount of ink to the substrate through a unique mesh roller. The appropriate use of ink is directly related to the printing production operation and pr...
Architectural coatings mainly use water as a dispersing medium and diluent, and its advantages are that the water of the dispersing medium is non-toxic and harmless, manufacturing and storage and transportation without the danger of explosion, no pollution to the environment, and to solve the problem of excessive VOC(volatile organic compounds) of solvent-based coatings at normal temperature. Film...
1.Type: There are three main types of water-based acrylic resins, including emulsion, water dispersion and aqueous solution. The emulsion is synthesized by emulsifying olefins in water under the action of water-based free radical initiator. The aqueous dispersion is synthesized by free radical solution polymerization or stepwise solution polymerization. Aqueous acrylics are directly soluble in wat...
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...
Fabric coating finishing is to evenly coat a layer of molecular film on the surface of the fabric to give the fabric with various functions and expand the use of the fabric. Compared with other coating materials, polyurethane coating has high tensile strength, large elongation, good elasticity, good wear resistance, heat resistance, low temperature resistance and aging resistance, and is a hi...
The method of using silane coupling agent mainly includes pretreatment method and integral blending method. When using silane coupling agent, it is necessary to choose the appropriate method and conditions according to the specific situation. At the same time, it is also necessary to pay attention to the amount and time of use of silane coupling agent to ensure that it can play the best ...
What is Water-based acrylic Emulsion? How is water-based acrylic emulsion classified? Water-based acrylic emulsion is a type of emulsion that is produced by emulsion polymerization, in which various monomers of acrylic acid are polymerized. This emulsion is widely used in the coatings, adhesives, paper, and textile industries. The production process can be simply described as follows: First, mix p...
