Laminating glue is currently a kind of strong glue widely used in the market, so what is the application processing process of laminating glue? The application processing technology of laminating glue is as follows: 1, the composite method is dry composite, that is, the coating machine should use a dry composite machine with curing furnace and composite roller heating. 2, curing furnace ambient te...
In the production process of water-based polyurethane to add a certain type of additives, it is necessary to pay attention to its role in the various stages of storage, construction, application, and consider and evaluate its role and impact in the next section. For example, when the water-based polyurethane paint is operated with wetting and dispersing agents, it plays a certain role in storage a...
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 ...
After the ink is stored for a period of time, the upper part of the ink appears thin in the container, the viscosity is small, and the color and concentration are relatively poor; The lower part is thick, the viscosity is large, and the color and concentration are also relatively good. Intaglio printing inks are thin and have a small viscosity, because the pigment is poorly dispersed in the connec...
What is a peelable resin? Strippable resin is a special resin material with strippable properties (also known as removable film resin). It is often used in the preparation of protective films for electronic products, packaging of semiconductor devices, etc., which can protect these products more intact, and it is easy to peel off when it needs to be replaced or disassembled. When prepari...
1. Coatings field: Waterborne polyurethane is widely used in waterborne printing inks, wood coatings, metal coatings, automotive coatings, architectural coatings and other fields because of its small curing shrinkage rate, good acid and alkali resistance, wear resistance, weather resistance and chemical stability. 2. Adhesive field: Waterborne polyurethane adhesive has shear vi...
Protective film resin Automobile coating resin High resilience waterborne polyurethane resin 1.Typical properties Appearance： Milky white liquid Protective film resin Automobile coating resin Ph： 7.0-9.0 Automobile coating resin Solid content： 40±1% Charge： Anionic High resilience waterborne polyurethane resin Viscosity (25℃)： 300-800cP Elongation (%)： >200...
Color paste, also known as pigment paste, is an important form of dye application, which is widely used in textile, ink, paint and other industries. In the classification of pastes, low-halogen pastes and ordinary pastes are two common types. They have certain differences in composition, performance and use, and the differences between the two types of pastes will be discussed in detail below. Fir...
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 performance requirements of water-based varnish for printing paper glazing are as follows: 1.The film has good environmental resistance. Some of the printed matter after glazing is used to make all kinds of packaging cartons, in order to be able to play a good protective effect on the packaged products, the environmental resistance of the glazing film layer must be better. For example, the pac...
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...
Ink scraping is not clean troubled many manufacturers, there are ten reasons for scraping is not clean, save it for use! 1.Ink viscosity is too high When the viscosity of the ink increases, the surface tension also increases correspondingly, and the force between them also increases, so that the scraper will increase the impact force of the ink on the scraper in the contact process with the ink, d...
First, material selection and preparation To make the resin crack effect, you first need to prepare the resin and pigment. Resin selection of high transparency, high hardness, wear resistance products, pigments can choose mineral pigments or metal pigments, you can also add a small amount of color pigments to prepare a rich color. Second, color mixing Mix the paint into the resin one by one and st...
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...
Water-based ink is referred to as ink, and flexible water-based ink is also known as liquid ink, which is mainly made of water-soluble resins, organic pigments, solvents and related additives by composite grinding processing. Water-based ink is especially suitable for tobacco, wine, food, beverages, medicines, children's toys and other packaging and printing products with strict sanitary condition...
