What is a coupling agent? Coupling agent is a class of substances with amphoteric structure, a part of their molecules coupling agent is a class of substances with amphoteric structure, a part of their molecules can be divided into groups and inorganic surface chemical groups reaction, forming chemical bonds; The groups can react with the chemical groups on the inorganic surface to form chemical b...
In the process of coating manufacturing, it is necessary to belong to the hydrophilic polar material Yan, fillers dispersed to belong to the hydrophobic non-polar material organic base material.In order to increase the affinity between inorganic matter and organic polymer, it is generally necessary to use coupling agent or other surfactants to treat the surface of inorganic matter, so that it chan...
Coupling agent is a kind of material with two different properties of functional groups, the biggest characteristic of its molecular structure is that the molecule contains two groups with different chemical properties, one is an inorganic group, easy to react with the inorganic surface; The other is an organophile group, which can react with synthetic resins or other polymers or form hydroge...
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...
Advantages and disadvantages of the same type of defoamer Organic defoamer such as mineral oils, amides, low alcohols, fatty acids, fatty acid esters and phosphate esters has been studied and applied earlier, belonging to the first generation of defoamer, which has the advantages of easy access to raw materials, high environmental performance and low production cost.The disadvantages are low defoa...
Defoamer is a substance with low surface tension and high surface activity, which can inhibit and eliminate foam in the liquid, that is to say, defoamer can reduce the surface tension of water, solution, suspension, etc., to prevent foam generation or eliminate the original foam.Long-term defoaming is also known as defoaming, and the length of the defoaming time is the main sign of the quality of ...
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...
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...
