As early as 1872, the German chemist Bayer (A.Bayer) first discovered phenol and formaldehyde when heated under acidic conditions can quickly form a red-brown lumps or viscous material, but they can not stop using the classic method for purifying experiment. After the 20th century, a large number of phenol has been obtained from coal tar, formaldehyde as a preservative but also mass production, so the reaction product of the two is more interesting, I hope to develop a useful product, although there have been spending a lot of people of a huge labor , but did not achieve the desired results. In 1904, Baekeland and his assistant also carry out this study, Qingdao resin, originally designed just want to be made instead of natural resin varnish resins Tai'an, Jinan resin after three years of hard work, and finally in the summer of 1907, not only made out of resin varnish, but also made a truly synthetic plastic material --Bakelite, it is known as "Bakelite" "bakelite" or phenolic resins. High temperature paint coating generally refers to a coating film do not change color over 200 ℃, does not fall off, can still maintain adequate physical properties paint. Under normal circumstances, high temperature powder coating is mainly composed of high temperature resin, high temperature pigments, fillers and the effects of high temperature additive composition; its outstanding high temperature performance and are widely used in chemical, petroleum, metallurgy, aviation and other industries. Currently still resistant powder coating powder coating of silicone based. Jinan resin | Boshan Light Chemical (certified) | Zibo Boshan resin by light chemical plant.
