Titanate coupling agent manufacturers tell you the precautions for using silane coupling agents and how to choose them
Titanate coupling agent manufacturers tell you the precautions for using silane coupling agents. 1. According to the principle of chemical reaction, silane can only exert its coupling effect under hydrolysis conditions, but this does not mean that water must be added to the system. The water adsorbed in the material and the water vapor in the air can usually meet the requirements of hydrolysis. Whether or not the silane is prehydrolyzed depends on the specific conditions.

Follow the titanate coupling agent manufacturer to see what is a coupling agent and its selection principles
What is a coupling agent? The titanate coupling agent manufacturer said that the coupling agent is a substance with a two-property structure. Some groups in its molecule can react with chemical groups on the surface of inorganic materials to form chemical bonds; another part of the groups have organic affinity. It can chemically react with organic molecules or produce strong intermolecular interactions, so that two materials with completely different properties can be firmly combined. Since most coupling agents can chemically treat the surface of the filler, the effect is very good, which can effectively improve the dispersion state of the inorganic filler in the polymer matrix, and improve the mechanical properties and performance of the filled polymer material.
Titanate coupling agent manufacturers come to learn about the application of organic titanium coupling agents
Titanate coupling agent manufacturers have learned that the application of organic titanium coupling agents improves the compatibility of inorganic fillers and resins, improves processing flow, increases filling amount, improves physical and mechanical properties of products, improves product surface smoothness, and reduces production costs. Wait.
Titanate coupling agent manufacturers share six functions of titanate coupling agent for you
Titanate coupling agent has good coupling effect in thermoplastic, thermosetting plastic, rubber and other filler systems. The general structural formula of the monoalkoxy type coupling agent is: RO-Ti(OX-R-Y)3. The representative variety is Sancheng Nitrate Dipropyl Titanate (TTS), which is suitable for calcium carbonate fillers. Below, titanate coupling agent manufacturers share the six functions of titanate coupling agent:
Titanate coupling agent manufacturers introduce you an all-round coupling agent
Titanate coupling agent appeared in the 1970s. In December 1974, a petrochemical company reported a new type of joint system with good coupling effect on many dry powders. Since then, polyolefin composite materials filled with inorganic substances with titanic acid joint agent have been introduced one after another. In recent years, newly developed titanate coupling agents have been widely used. The addition of titanate coupling agent-activated carbon black, SiO2, CaCO3, and metal oxides to thermoplastics and rubbers can reduce system viscosity and improve toughness and mechanical properties. At present, titanate coupling agent has become one of the indispensable raw materials of composite materials.
What are the functions and performance characteristics of silane treatment agent? What should I pay attention to when using it?
After entering the 21st century, with the rapid development of the world economy, the metal surface treatment technology is also constantly improving and improving in the changing times. At present, new and more environmentally friendly silane treatment technologies are being developed at home and abroad. The silane treatment agent technology is suitable for treating cold-rolled steel sheets, aluminum materials, zinc, aluminum alloys and other metal substrates, among which galvanized steel sheets are less effective. The in-line production process of a variety of substrates can be realized, and the treatment effect is related to the treatment method (the effect of silane spraying is better than that of dipping, because the latter is more stringent).
