The Introduction of Epoxy Silanes

图片
  Epoxy silanes are colorless and transparent liquids, which are easily soluble in a variety of organic solvents, easily hydrolyzed, condensed to form polysiloxane, and is easily polymerized in the presence of overheating, light, and peroxide.   1. Application field Glass fibers, adhesives, resins, fillers, plastics, textiles, coatings   2. Main purposes Epoxy silanes  mainly used to improve the bonding performance of organic materials and inorganic materials, such as glass fibers in glass fiber reinforced plastics, plastics, rubbers, paints, siliceous fillers in coatings and other materials. Moreover, it also used in adhesives to increase bonding performance and its suitable resins include epoxy, phenolic, melamine, polysulfide polyurethane, polystyrene, etc.   They Improve the adhesion of inorganic fillers, substrates and resins, thereby improving the mechanical strength and electrical properties of the composite material, and have a higher retention rate in the wet condition. As a s

The Use of Silane Coupling Agents in Quartz Powder

图片
  Active quartz powder can have the crosslinking reactions with the resin and the curing agent. But it will not promote or retard the curing reaction of the resin and the curing agent system, nor will it affect the casting process. Active quartz powder is widely used in industries such as the casting of medium and high voltage electrical appliances and the packaging of electronic materials. It is a kind of non-toxic, odorless and non-polluting hydrophobic (lipophilic) high-purity white powder, with good temperature resistance, acid and alkali corrosion resistance, poor thermal conductivity, high insulation, low expansion, stable chemical properties, high hardness and other excellent performances. While being used in polyolefin plastics, it will not reduce the MFR value, which has good affinity and does not absorb water, making ordinary plastic products obtain better impact strength, stiffness, and improve physical properties such as cold and heat resistance.   The main uses of silane c

The Important Role of Hubei Silane Coupling Agents in Galvanizing

图片
  Galvanizing is currently one of the most important methods for surface protection of steel at home and abroad. Galvanized steel sheets are widely used in automobile manufacturing, home appliances, construction and aviation because of their good corrosion resistance. However, the galvanized layer is easily corroded in the air or in a humid environment, producing white corrosion products which affect the appearance, and reduce the corrosion resistance. In order to slow down the corrosion rate of the galvanized layer and prolong its service life, the galvanized layer needs to be surface passivated to improve its corrosion resistance. Chromate passivation is widely used in metal passivation due to its simple process, low cost, and good passivation effect. However, Cr6+ is a highly toxic substance with carcinogenicity which does severely harm to the human body and the environment.   In recent years, hubei silane coupling agents are the new type of anti-corrosion treatment process. Because

The Use Range of the Amino Silane Coupling Agent

图片
  Amino silane coupling agents are mainly used for glass fiber reinforced plastics. Siloxy are reactive to inorganic substances, and organic functional groups are reactive or compatible to organic substances. Therefore, when the amino silane coupling agent  is between the inorganic and organic interface, it can form a bonding layer of organic matrix-aminosilane coupling agent-inorganic matrix.   The use of amino silane coupling agents  can be roughly summarized into three aspects.   1. Appearance treatment It can improve the bonding function of glass fibers and resins, and greatly improve the strength, electricity, water resistance, weather resistance and other functions of glass fiber reinforced composite materials. Even in the wet condition, it has a great significant effect on the improvement of the mechanical functions of composite materials. The use of amino silane coupling agents in glass fibers has been appropriately widespread, and the amino silane coupling agents used in this

  1. 3-(2,3-glycidoxy) propyl trimethoxysilane is a coupling agent containing epoxy groups   3-(2,3-glycidoxy)propyl trimethoxysilane  often used for polysulfide and polyurethane caulking and sealants, epoxy resin adhesives, filled or reinforced thermosetting resins, glass fiber adhesives, and inorganic filled or glass reinforced thermoplastic resins.   2. Improve the adhesion between the resin and the matrix or filler Enhance the electrical properties of epoxy-based electronic sealants and packaging materials and printed circuit boards, and improve the adhesion between the resin and the matrix or filler.   3. Superior performance on various metal surfaces It can enhance the electrical properties of many inorganic-filled nylon and polybutylene terephthalate composite materials. It is effective for a wide range of fillers and substrates, such as clay, talc, wollastonite, silica, quartz or metals such as aluminum, copper and iron. Including: epoxy sealant filled with quartz, pre-mixed fo
