About epoxy resin

1. What is epoxy resin

Answer: Epoxy resin refers to organic polymer compounds containing two or more epoxy groups in their molecules. Except for a few, 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, which can be located at the end, middle, or in a cyclic structure of the molecular chain. Due to the presence of active epoxy groups in their molecular structure, they can undergo cross-linking reactions with various types of curing agents to form insoluble and non melting polymers with a three-dimensional network structure.

How many types of epoxy resin are there

Answer: There are five major categories of epoxy resins: glycidyl ether, glycidyl ester, glycidyl amine, linear aliphatic, and cycloaliphatic

When did epoxy resin appear

Answer: As early as 1891, Lindmann from Germany reacted hydroquinone with epichlorohydrin, condensed it into resin, and cured it with acid anhydride. The development of epoxy resin in China began in 1956 and achieved success in Shenyang and Shanghai.

What are the uses of epoxy resin

Answer: 1. Coatings field 2. Composite materials field 3. Adhesive field

What are the requirements for the use of epoxy resin in coatings

Answer: As their respective properties are not perfect, and the objects to which epoxy resin is applied are not uniform, there are also requirements for the performance of epoxy resin according to the different objects used. For example, some require low-temperature fast drying, some require excellent insulation performance, and some require anti-corrosion performance as the top priority. The type of resin should be selected according to the requirements.
