The advantages of thermosetting epoxy resin, how much high temperature resistance of epoxy resin

The ** of epoxy resin glue is about dozens of yuan per kilogram, the cheap one is more than ten or twenty yuan, and the expensive one is one or two hundred yuan. Different types of epoxy resin adhesives are also different. As far as the category is concerned, the classification of epoxy resin has not yet been unified, generally according to the strength, heat resistance grade and characteristics of classification, the main varieties of epoxy resin have 16 kinds, including general glue, structural glue, temperature-resistant glue, low-temperature glue, underwater, wet surface glue, conductive glue, optical glue, spot welding glue, epoxy resin film, styrofoam, strain glue, soft material adhesive, sealant, special glue, cured glue, civil construction glue 16 kinds.

The classification of epoxy resin adhesives in the industry also has the following divisions: 1. According to its main composition, it is divided into pure epoxy resin adhesive and modified epoxy resin adhesive; 2. According to its professional use, it is divided into machine....

Epoxy resin is resistant to high temperature 180. Generally, in the absence of oxygen, the thermal decomposition temperature of epoxy resin body is above 300. When used in air, thermal oxidative decomposition generally occurs at 180 200.

Epoxy resin is a general term for a class of polymers that contain more than two epoxy groups in the molecule. It is a polycondensation product of epichlorohydrin with bisphenol A or polyols.

Due to the chemical activity of epoxy excitation, it can be used to open the ring with a variety of compounds containing active hydrogen, solidify and cross-link to form a network structure, so it is a thermosetting resin. Bisphenol A epoxy resin not only has the largest output and the most complete variety, but also the new modified varieties are still increasing, and the quality is constantly improving.

Epoxy resin refers to a general term for a class of polymers that contain more than two epoxy groups in the molecule. It is a polycondensation product of epichlorohydrin with bisphenol A or polyols.

Due to the chemical activity of the epoxy group, it can be used to open the ring with a variety of compounds containing macro-active hydrogen, solidify and cross-link to form a network structure, so it is a thermosetting resin. Bisphenol A epoxy resin does not disturb the car only has the largest output and the most complete variety, and the new modified varieties are still increasing, and the quality is constantly improving.

How to use epoxy resin:

When using epoxy resin, it is generally necessary to use it in combination with an epoxy resin curing agent. Before use, the epoxy resin and the epoxy resin curing agent should be mixed according to the ratio of 1:1, and the two should be fully stirred before they can be applied to the position where they need to be bonded.

If the epoxy resin is bonded on the straight side or upside down surface, then after applying the mixed solution of epoxy resin, it is necessary to use tape or 502 to fix the adhesive to avoid the phenomenon of dislocation of the adhesive, which will affect the bonding effect of the epoxy resin.

In order to ensure the adhesion of epoxy resin, it is better to use it at a temperature between minus 50 and 150 degrees. If it is at room temperature, it usually takes about 6 hours for the epoxy resin to cure. If the temperature is 40 degrees Celsius, it will cure in about 3 hours.

If it is to be cured thoroughly, it will take about ten days, and the bonding effect is the best at this time. If it is rainy and humid weather, it is generally necessary to heat the indoor temperature to about 20 degrees Celsius before using epoxy resin. <>

Summary. Hello, 260 to 310 degrees.

The temperature resistance of epoxy resin board is usually 175 degrees, and the maximum temperature resistance can reach 260 to 310 degrees, so it can be used in various metals, ceramics, glass, wood, stone, bamboo and other non-metallic materials pasting, and is very widely used and very practical.

How much can epoxy resin withstand high temperatures.

Hello, 260 to 310 degrees epoxy resin board temperature resistance is usually 175 degrees, the highest temperature resistance can reach 260 to 310 degrees, so it can be used in a variety of metals, ceramics, glass, wood, stone virtual materials, bamboo and other non-metallic materials paste, the use of very wide range of slag, poor practicability Liang orange is very strong.

Bisphenol A epoxy resin not only has the largest output and the most complete variety, but also the new modified varieties are still increasing, and the quality is constantly improving.

Epoxy resale resin curing agent is an organic polymer compound with epoxy groups. Epoxy resin floor paint with this composition has the characteristics of strong acid and alkali resistance, wear resistance, pressure resistance, impact resistance, mildew resistance, waterproof, dustproof, anti-slip, anti-static, electromagnetic wave and so on. Next, let's learn about epoxy resin curing agent brand recommendations.

What is Epoxy.

Epoxy resin refers to organic polymer compounds that contain two or more epoxy groups in their molecules, and their relative molecular mass is not high except for a few. 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. Because the molecular structure contains active epoxy groups, they can cross-link with various types of curing agents to form insoluble, non-meltable polymers with a three-way network structure.
