1, pro! Please consult us before you take the picture. Please don't take any details about the specifications, freight, delivery time, etc.! Without consulting customer service, free to take products, our shop is not shipped, do not bear joint liability, the consequences of their own. We are always at your service, waiting for your advice!Hotline: 13592774239, Miss Huang welcome your consultation!
2, if it is especially accurate, please and service, because the cutting loss tolerance, bumps, there may be individual will scratch the phenomenon, if not, we will accept as default.
3, if you need other express, please explain, in addition, if some of the larger size is generally send logistics! The buyer must carefully check the goods after receipt of goods and then sign.
4, customer orders, the general delivery is the day, and some of the more complex, may be more than 1 days or so shipped, because customized products need a production schedule, if the more urgent customers must and customer service instructions.
5, on the return of goods: if the goods are cut according to customer requirements, our shop does not accept the exchange treatment, because the plate is cut according to your requirements, can not be sold for two times, please confirm the specifications and requirements of the cutting before the order. If the customer buys the whole piece of goods, we can accept, return, deal with, return goods, back and forth freight by the buyer.
6, all the commodity prices are tax free prices, the company has exclusive value-added tax invoices, if necessary Invoicing service, please contact customer service.
Thank you for your cooperation. I wish you a happy shopping!

Epoxy resin is a kind of organic macromolecular compound containing two or more than two epoxy groups. Except for some, their relative molecular weight is not high. The molecular structure of epoxy resin is characterized by the presence of active epoxy groups in the molecular chain, and the epoxy group can be located at the end, intermediate or ring like structure of the molecular chain. Because of the active epoxy groups in the molecular structure, they can be cross-linked with various types of curing agents to form insoluble, non melting polymers with three directional network structure.
Edit this paragraph application characteristics 1, diverse forms. Various resins, curing agents and modifier systems can almost meet the requirements of various applications for the form, ranging from very low viscosity to high melting point solids.
2, easy curing. The epoxy resin system can be cured almost in the temperature range of 0~180 degrees with various curing agents.
3, strong adhesion. The existence of polar hydroxyl groups and ether bonds in the molecular chain of epoxy resin makes it highly adhesive to various materials. When epoxy resin is cured, the shrinkage is low and the internal stress is small, which also helps to improve the adhesion strength.
4, low contractility. The reaction between epoxy resin and curing agent is carried out by direct addition reaction or ring opening polymerization of oxygen in the resin molecule. No water or other volatile by-products are released. Compared with unsaturated polyester resin and phenolic resin, they show very low shrinkage (less than 2%) during curing.
5. Mechanical properties. The cured epoxy resin system has excellent mechanical properties.
