Automotive powertrain adhesive, high temperature resistant adhesive for engine parts

Automotive powertrain bonding parts mainly include screw and bolt fastening and sealing, cylinder gasket sealing, automotive manufacturing industry is more used in anaerobic adhesives, will be used for thread fastening locking, with the fixed parts of the plane bonding, pipeline and flange sealing and pinhole sealing, can be solved to prevent loosening, leakage and other issues, to simplify the assembly process.

　　Automotive power system in the engine casting produced when the trachoma, a variety of bolts fastening, pipeline sealing and plane sealing, etc. are mainly used in various types of anaerobic adhesive. Engine casting when produced when produced by water glass infiltration sealing effect is poor, and the use of high-temperature anaerobic adhesive infiltration can obtain good sealing effect.

　　High-strength anaerobic adhesive can be used for engine cylinder head and gearbox double head bolts, as well as infrequently disassembled bolts, collective process body, cylindrical bowl-shaped plug drive axle differential case connecting bolts, round shaft gears and differential fixing bolts, etc., fixed and sealed. In addition, automotive gaskets can not guarantee the sealing performance and the geometric accuracy of the coupling mechanism, and the use of anaerobic adhesive for plane sealing can solve these problems. Low-strength anaerobic adhesives can be used for parts that are easy to disassemble.

　　Automotive powertrain adhesives usually need to have high temperature, high pressure, oil, water and other properties to ensure that the complex working environment can maintain the bonding effect. Generally speaking, the adhesive used in the automotive power system mainly includes high temperature adhesive, sealant, structural adhesive and special adhesive and other types.

　　Specifically, for example, in the engine components, need to use high temperature adhesive, used to fix and seal high temperature parts, such as the crankcase, cylinder head, etc.; in the transmission system, may use damage-resistant, oil-resistant structural adhesive, used to fix the transmission components; in the exhaust system, the need to use high temperature, corrosion-resistant sealant, used to seal the exhaust pipe interface.

　　For specific adhesive selection and use, it is recommended that you consult a professional automotive maintenance personnel or manufacturers to ensure that the selection of adhesive products suitable for specific parts and working environment. At the same time, in the process of use must be in accordance with the instructions on the instruction manual to ensure safety and reliability.
