As a kind of widely used adhesive, coated adhesive has a variety of processes. Here are some of the common processes used: 1. Hot melt coating: hot melt coating is to place a layer of film on the surface of the print, and then through hot pressing the film and the print together.In this process, the laminating glue is heated to turn it into a liquid, which then forms a uniform coating between the ...
As an important material for printing, ink is composed of resin, pigment, filler and auxiliary. Due to many industries such as books, packaging, construction, and circuit boards, with the gradual increase in social demand, the use of ink is also increasing. However, in the production and use of ink, due to the addition of surfactants, equipment stirring operation and environmental changes will cau...
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...
In the process of UV flexographic printing, the viscosity of the ink is one of the key factors that affect the printing quality and effect. Choosing the right viscosity UV flexographic ink is crucial to ensure printing quality and efficiency. When adjusting viscosity, it is usually necessary to consider many factors such as printing equipment, printing materials, image details and the expected pri...
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...
Coupling agents have always been an amazing additive Coupling agents, also known as surface modifiers, are a special type of additive that Coupling agents, also referred to as surface modifiers, are a particular type of additive that is dedicated to optimizing the interfacial characteristics among the adhered substrate, fillers, and polymeric materials, significantly enhancing the binding for...
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 ...
(1)KH-550 silane coupling agent ①Alias: 3 triethoxysilylpropylamine; AMEO CAS : 919-30-2 Colorless or very pale yellow transparent liquid. It is soluble in organic solvents, but acetone and carbon tetrachloride are not suitable as diluents. It is soluble in water and hydrolyzes in water. The amino functional silane is basic, has high reactivity, and is highly versatile. The silicon portion of...
The world's coating variety structure is developing in the direction of reducing VOC, and water-based coating is one of the development directions. The proportion of traditional solvent-based coatings in China has gradually declined, and the development speed of water-based coatings is also very fast, but the low-grade varieties of polyvinyl alcohol still account for a large proportion. When choos...
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...
Coating finishing is a branch of textile finishing, which endows fabrics with special properties through coating methods. Acrylic emulsion agents with a solid content of 40% have good water pressure resistance and air permeability, and have been widely used in the coating finishing of polyester-cotton trench coats, polyester-cotton, nylon bone snow shirts and other fabrics. After adding ...
01 Polyurethane emulsion exhibits excellent adhesion properties in fabric finishing, making it an ideal fabric finishing agent. Fabrics treated with polyurethane emulsion not only have good wash resistance and stiffness, but also possess anti-shrinkage, anti-wrinkle properties and a good hand feel. When used in combination with polyacrylate, the effect is even better. For example, in cot...
