The internal structure of waterborne acrylic emulsion particles will affect several aspects of waterborne paint formulations.According to the order in which the effects are affected, the phase structure will first affect the selection and addition of the filming aid.Different phases have different hydrophilic/lipophilic characteristics, and the oleophilic properties of various coalescents are diff...
Thank you for the New Year gift of our company. In the New Year, we hope to make our products better and serve our customers better,Hope the performance increase day! Sinograce Chemical wish you a happy New Year!
1.The cause of a back adhesion： (1)the paste itself anti-viscosity, especially in the wet weather easy to stick back; (2)After the printing is completed, it is packaged without perfect heat treatment; (3)adjust the slurry formula is not appropriate, adding too much transparent slurry easy to cause back adhesion; (4)transport or storage conditions are not good, in high temperature, high humidity co...
The choice of solvent In the printing ink manufacturing process, in consideration of the overall solvent system of the ink volatility, to improve the printing ink solvent release and reduce the solvent organic solvent residue, the use of solvents are often several volatile mixed solvents.In the printing ink manufacturing process, the main organic solvents are toluene, butanone, cyclohexanone, ethy...
1.Introduction to silicone acrylic emulsion Silicon-acrylic emulsion is a kind of composite emulsion. It is a copolymer emulsion of organosilicone and acrylate.Acrylic resin has many excellent characteristics, such as weather resistance and light resistance, long time under ultraviolet irradiation is not easy to yellow。In addition, it also has flexibility, so it is often used as a leather finishin...
In July 2021, our company held a home party building activity, in order to welcome new employees, to show our team's enthusiasm and unity. Hope the company is developing better and better, welcome customers to consult our polyurethane coating, acrylic emulsionand other resins .
What are the uses of waterborne acrylic emulsions? Waterborne acrylic emulsion is used as finishing agent for silk fabrics and leather Water based acrylic emulsion is used as finishing agent and treating agent for photographic printing paper Waterborne acrylic emulsion has good sealing performance on wood grease and tannic acid, used as transparent sealing primer for wood,...
Printing mucilage requirements The requirements of printing mucilage for manual plate printing Manual table printing is to press the screen on the fabric of the table for manual scraping, and the pressure extrusion on the scraper will print the glue through the mesh hole of the pattern part to the fabric. The shear stress of the binder is small, so thePrinting mucilageis required to have good...
Solvent selection In the printing ink manufacturing process, considering the overall solvent system of the volatile ladder, improve the printing ink solvent release and reduce printing solvent organic solvent residue, the solvent used is often a mixture of several volatile solvents. In the printing ink manufacturing process, the main organic solvents are toluene butyl ketone cyclohexanone ethyl ac...
On January 26, 2022, SINOGRACE Chemical Co., Ltd. will hold the year-end summary meeting and annual convention, and wish everyone a happy New Year.
When waterborne polyurethane is used as adhesive, it must be mixed generally. Based on waterborne polyurethane, crosslinking agent, thickening agent, filler, plasticizer, pigment and other additives can be added. Other types of waterborne resin and water can be added.In order to obtain higher resistance to water Heat resistance and bonding strength, at present a lot of waterborne polyurethane syst...
Water - based ink is composed of adhesives pigment additives and other substances such as uniform slurry material,Binders provide ink with the necessary transfer properties, pigments give ink color. Water-based ink linker is mainly divided into two types: water dilution and water dispersion.The former can be used in many types of resin, such as maleic acid resin lac maleic acid resin modified shel...
Flexo printing ink characteristics: 1 Water-based ink (mainly used for paper printing) Water-based ink is the biggest characteristic, the use of water-soluble or water-dispersive resin as a linker, reduce the discharge of organic volatile matter, it can completely eliminate some toxic substances to the human body and the pollution of packaging goods.Water-based ink makes less investment in environ...
With the improvement of social progress and people's awareness of environmental protection, water-based ink in the field of packaging printing ink has attracted much attention.Water-based ink is more widely used in the fields of paper, food, medicine, packaging and printing because it has very low organic volatile matter (VOCs) and green environmental protection. However, in the field of gravure p...
Water-based adhesives are environmentally friendly adhesives made of natural or synthetic macromolecule as adhesives and water as solvent or dispersant instead of toxic organic solvents that pollute the environment.Existing water-based adhesives are not 100% solvent-free and may contain limited vocs as additives for their aqueous media in order to control viscosity or fluidity.Advantages are mainl...
Water-based ink resin is the carrier of pigment in ink, is the core material of ink, its quality, will directly affect the performance of ink, because water-based ink resin to a large extent determines the viscosity of ink, dry fluidity and other properties.Anti - viscosity is an important physical property index of printing ink.Intaglio printing is a kind of printing with high order ink supply, g...
