Polyurethane is the short form of polyurethane (PU). It is a block polymer formed by addition polymerization. It is a polymer compound with flexible and elastic polyether or polyester as soft segment and rigid and hard carbamate as hard segment. It contains a considerable number of ammonia ester bonds. Waterborne polyurethane has been successfully applied in the textile printing and dyeing industr...
The addition of wetting dispersant has obvious effect on the foam of some water-based ink.For example, polyacrylic acid wetting dispersants foam more than other types of wetting dispersants.Generally speaking, wetting dispersant foam with low dispersion capacity is also less. If diisobutyl sulfonate is based on disate, there is little foam at its content of 0.1-0.25%. The use of thickeners will ma...
Water - based ink is also known as water - based (oil) ink, referred to as ink.Water-based ink is made of water-soluble or water-dispersed polymer resin, colorant, surfactant and other related additives through chemical process and physical processing. Water - based ink containing a small amount of alcohol water as solvent, ink stability.Therefore, it is especially suitable for food, medicine and ...
Environmental protection pressure has prompted some traditional solvent-based products to gradually withdraw from the market and replace them with water-based, high solid content, powder products, etc.Waterborne polyurethane, as an important member of waterborne products, is facing unprecedented development opportunities with its unique excellent properties.In addition to the leather industry, it ...
First: Teflon coating introduction Industrial Teflon coating is suitable for plastic rubber mold, ball mold, glove mold, latex mold, roller, conveyor belt, mechanical parts and other surface treatment, containing "FEP" and "PTFE" polytetrafluoroethylene ingredients with high-performance resin, divided into the bottom coating and surface coating a total of two layers, has the best anti-corrosion, h...
1.Water as a dispersion medium, do not use organic solvents, non-toxic or flammable danger, is environmentally friendly products; 2.Acrylic monomers have many types, containing ester groups, carboxyl groups, hydroxyl groups and other functional groups have strong polarity, it is easy to emulsion copolymerization with other monomers such as vinyl acetate, styrene, vinyl chloride, etc., to make emul...
Surfactants play the role of wetting, dispersing, emulsifying and solutizing in pesticide processing, and have become one of the indispensable components of pesticide preparations, and are often called auxiliaries, emulsifiers, dispersants, auxiliary agents, etc., they can be a combination of a variety of surfactants.At present, pesticide formulations are developing in the direction of waterborne,...
Pigment printing The printing method of coating printing is that the non-water-soluble substance particles with color or special effect are adhered to the fiber/fabric surface with a polymer adhesive to form the desired pattern. Paint printing characteristics 1.the process is simple and convenient, wide applicability to fibers; 2.Complete chromatography, bright color; 3.Clear outline and distinct ...

As a professional manufacturerof label and package printing coating industry, Anhui Sinograce Chemical Co., Ltd took part in this LABELEXPO Europe-2023 exhibition.he exhibition focused on showing the company's coatings in the field of coatings, including water-based label adhesive and water based paper adhesive,top and primers coating, Other Adhesive,coating additives,film etc. In the four da...
Depending on the coating material used, the type of coating is also different. PVDC coating, PVOH coating, silicon oxide (Si0x) coating, Acrylic (Acrylic) coating these four kinds of plastic coating characteristics and applications are introduced. According to the different coating materials used, plastic coating mainly has the following types: 01/PVDC coating PVDC emulsions can be coated in sever...
The adhesive not only needs it to stick firmly, but also needs long-term viscosity, the effect of the adhesive is better, if it can not be sustained, after a period of time it will fall off, or for some reason, the viscosity will decline, so we sometimes need to think of some ways to ensure the durability of the viscosity. Research work and experience have shown that adhesives can bond things by i...
With the rapid development of printing and packaging industry, the appearance design of products is becoming more and more high-end. The composite technology used in modern exquisite printing mainly includes: paper printing and plastic film composite and plastic printing and plastic film composite, that is, paper-plastic composite and plastic-plastic composite.As a new type of packaging material, ...
With the progress of science and technology, the printing technology industry is also developing rapidly, and more and more adhesives are used in the packaging and printing industry, and more and more varieties are also available. The film coating process is widely used in a variety of packaging, small to medicine boxes, crafts boxes, large to outer boxes and various product packaging. Some coatin...
Whether the water-based film adhesive meets the quality requirements of composite products, in addition to the quality of the glue itself, but also related to the paper, film, equipment accuracy, operating experience and other supporting factors in the film coating process, after long-term practice, we summarized the common problems in the application of water-based film adhesive, and put forward ...
Non-stick coating refers to the coating formed after coating with low surface energy, easy to clean and other characteristics of the coating, which is widely used in all kinds of food contact, hardware products, mechanical parts, chemical equipment, electrical equipment. Non-stick pans are also the most widely recognized non-stick paint application scenarios. 1. non-stick coating has fluorine resi...
