What kind of glue is used to bond car bumpers?
1 Answers
Car bumpers can be bonded using epoxy resin adhesive. The relevant introduction to epoxy resin adhesive bonding is as follows: Usage method: Use a dry cloth or sandpaper to remove dust, oil, rust, etc. from the bonding surface, then wipe with a cleaning agent such as acetone or trichloroethylene to clean the bonding surface; unscrew the front cover, mix component A and component B in the specified weight ratio (A:B=2:1) thoroughly and stir evenly before use. Usage precautions: Note that the mixture must be used within the operable time, otherwise it will solidify, leading to material waste. The highest strength can be achieved after 24 hours. After applying the adhesive, it will cure at room temperature in 2~6 hours, or in 1~3 hours at 40~50 degrees Celsius. It is recommended to use the bonded part 24 hours after application, and the adhesive strength will be better after ten days. In cold and humid weather, it is best to bond at a room temperature of 15~25 degrees Celsius.
