When choosing a suitable organic high-temperature adhesive, the following aspects can be considered:
I. Consider the temperature range of use
1. Clearly define the maximum and minimum operating temperatures of the application scenario. Different organic high-temperature adhesives have different temperature resistance performances. For example, phenolic resin adhesives may be suitable for a temperature range of 200°C to 300°C, while modified epoxy resin adhesives can be used for a short time at higher temperatures. 2. Consider the fluctuation of temperature. If there is a large fluctuation in the working temperature, it is necessary to choose an adhesive that can maintain stable performance under temperature changes.

II. Consider the properties of the bonded materials
1. Material types. Different adhesives have different bonding effects on different materials. For example, for materials such as metals, ceramics, and glass, it is necessary to choose an adhesive that has good adhesion to these materials. 2. Material surface conditions. If the surface of the bonded material is rough, oily, or has other impurities, the surface may need to be treated and an adhesive that can adapt to this surface condition should be selected.

III. Consider the bonding strength requirements
1. According to the stress magnitude that needs to be withstood in actual applications, choose an adhesive with corresponding bonding strength. For example, in occasions where large mechanical stress is endured, an adhesive with high bonding strength is needed. 2. Consider the stability of bonding strength in long-term use. Some adhesives may experience a decrease in bonding strength over time at high temperatures. It is necessary to choose a product with good long-term stability.

IV. Consider chemical corrosion resistance
1. If there are chemical substances in the application environment, it is necessary to choose an adhesive that can resist the erosion of these chemical substances. For example, in the chemical industry field, an adhesive that is resistant to corrosive substances such as acids, alkalis, and salts is needed. 2. Consider the interaction between chemical substances and adhesives. Some chemical substances may react with adhesives and affect the performance of adhesives. Adequate testing and evaluation are needed.

V. Consider construction technology and cost
1. Convenience of construction technology. Different adhesives may have different construction methods, such as spraying, brushing, and impregnation. It is necessary to choose an adhesive that is suitable for actual construction conditions. 2. Cost factors. Consider the price, service life, and maintenance cost of the adhesive, and comprehensively evaluate and choose a product with high cost performance.
