What are the types of high temperature resistant adhesives?

High temperature resistant adhesives are a type of special adhesive that can maintain good bonding performance under high temperature environments. According to their composition and characteristics, high temperature resistant adhesives can be divided into many types. The following is a summary and introduction of several major high temperature resistant adhesives:

1. Organic high temperature resistant adhesives
Polyimide adhesives
Temperature range: 300-500℃
Features: It has excellent mechanical properties, electrical properties and chemical stability, and is suitable for bonding advanced materials such as carbon fiber, titanium alloy, stainless steel, etc., as well as occasions requiring high temperature welding.
Heat-resistant epoxy adhesive, phenolic resin adhesive
Temperature range: usually between 232-316℃, depending on the formula and curing conditions.
Features: It can be used for a long time at higher temperatures, and has good bonding strength and chemical corrosion resistance.
Organic silicone adhesives and modified organic silicone adhesives
Temperature range: It can be used for a long time at -60~300℃, and can reach 350~500℃ for short-term use, and the instantaneous use temperature is as high as 800~1000℃.
Features: Contains silicon-oxygen bonds, has high heat resistance, and has good weather resistance and chemical corrosion resistance.
Heterocyclic adhesives
Temperature range: varies depending on the specific type, but generally has high heat resistance.
Features: The main chain of the polymer contains aromatic heterocycles, has a high melting point, good heat resistance, and is suitable for bonding in high temperature environments.

2. Inorganic high temperature resistant adhesives
ZS-1071 high temperature inorganic adhesive
Temperature range: 1500-2000℃
Features: It is made of inorganic materials such as silicates and aluminates as the matrix, and is prepared with appropriate additives. It has good high temperature resistance and adhesion, and is suitable for bonding various inorganic materials, such as metal to metal, metal to refractory materials, etc.
Other inorganic adhesives
Temperature range: up to 700-2980℃
Features: It is made of inorganic compounds, such as zirconium oxide, copper phosphate oxide and silicates, etc. It has high heat resistance and will not corrode materials. It is suitable for bonding in extreme high temperature environments.
3. Special types of high temperature resistant adhesives

Hot melt adhesives
Temperature range: 100-150℃ (melting temperature)
Features: It can melt and resolidify at high temperature, bond various materials such as metal, glass, ceramics, plastics, etc., and is suitable for high temperature processes that require rapid curing.
High temperature composite adhesives
Temperature range: 1800-2300℃
Features: It is composed of a variety of different adhesives, has good comprehensive performance and the ability to adapt to a variety of materials, and is widely used in various high temperature industrial production.

Summary
There are many types of high temperature resistant adhesives. It is very important to choose the right adhesive according to the specific application scenarios and needs. When choosing, factors such as the nature of the material, the use temperature, the bonding strength, and the working environment need to be considered. At the same time, attention should also be paid to the construction process and curing conditions of the adhesive to ensure that it can achieve the best bonding effect.
