Epoxy resin and curing agent has broad prospects for development!
A general name for the epoxy resin containing an epoxy group. Mainly by the propylene oxide and polyphenols (such as bisphenol A) and other condensation. Products with different molecular weight can be got according to different ratio and manufacturing method. Low molecular weight is yellow or amber high viscosity transparent liquid. High molecular weight is solid, melting point is generally 145 - 155 oC. Soluble in acetone, ethylene glycol, ethylene glycol, toluene, styrene, etc.. A polymer body hard reaction with polyamine, or other organic acid anhydride curing agent etc.. Odorless, tasteless, alkali and most solvent. Excellent adhesion to metal and non metal. Good heat resistance, insulation resistance, hardness and flexibility. Can be used as metal and non-metallic materials (such as ceramics, glass, wood, etc.) of the adhesive (adhesive force, commonly known as Wan Nengjiao). Also can be used to make paint, reinforced plastics or casting into insulation parts, etc.. It can also be used to treat like fabric, wrinkle, shrink, water play a role. Low molecular weight epoxy resin can be used as a stabilizer for polyvinyl chloride. The epoxy resin coating is the general name of the main components of the epoxy resin as the main component. Mainly used for electrical insulation and corrosion protection. Air dry type and dry type. For example, hot-melt epoxy coating, epoxy primer, epoxy putty etc..
Today, China is the world's largest consumer of epoxy resin. Data show that: epoxy resin in 2011 global consumption of 2 million 200 thousand tons, China's consumption of 900 thousand tons; to the end of 12th Five-Year global consumption will reach 3 million tons, while China's consumption will be more than 1 million 750 thousand tons, accounting for 58% of the world. Over the years, China epoxy resin production capacity has made great progress, at present the total capacity of the device has far exceeded the 175 million tons, and in the next three years, new capacity, to the "Twelfth Five Year Plan" at the end of the China epoxy resin production capacity for global consumption.
In recent years, the rise of epoxy resin industry with rapid development of China's manufacturing industry is matched, but with a lot of the rapid development of industry as, early light weight problem also exists in the epoxy resin industry; is when the ordinary based product development to a certain stage, the market demand of mass products began to become saturated, the high-end special epoxy resin products demand more and more and a period of structural adjustment of industry naturally come.
