Nantong Jiufu New Material Co., Ltd. Public information on trial production of 16kt/a epoxy resin, 8kt/a polyester resin, 8kt/a powder coating and by-product 3.8kt/a industrial salt project Published: March 10, 2023
Epoxy resins have secondary hydroxyl groups, which can react with isocyanates, and epoxy groups. Epoxy resin as a polyol directly added to the polyurethane adhesive containing hydroxyl components, using this method only hydroxyl to participate in the reaction, epoxy failed to react.
The classification of epoxy resin is not unified at present. Generally, it is classified according to strength, heat resistance grade and characteristics. There are 16 kinds of epoxy resin, including 16 kinds of general adhesive, structural adhesive, high temperature resistant adhesive, low temperature resistant adhesive, water and wet surface adhesive, conductive adhesive, optical adhesive, spot welding adhesive, epoxy resin adhesive film, foaming adhesive, strain adhesive, soft material adhesive, sealant, special adhesive, latent curing adhesive and civil construction adhesive.
When synthesizing polyester resin, if some other structures are introduced through chemical modification, the polyester resin can have the performance that it does not have, so as to achieve the purpose of improving and highlighting certain performance, so as to achieve special application performance requirements. Epoxy, acrylic and silicone modified polyester resins are used more.
The largest growth areas of China's powder coating market are: shipbuilding industry and pipeline industry. The problem is that the impact resistance and moisture absorption need to be improved and improved, the researchers focus on the modification of various base materials. Domestic production of pipeline anticorrosive epoxy powder coating in the storage stability and coating workability, compared with foreign high-quality products there is still a certain gap. Due to the progress of foreign automobile powder coating preparation technology, automobile cover light, wood and plastic coating are the most dynamic potential markets. The automotive industry will be its major consumer, Greece, Turkey and Eastern Europe powder coating market growth momentum is very good, the Asia Pacific market potential is greater, has been considered the world's fastest growing region.
