Acrylic structural adhesive has the characteristics of fast curing and high strength, and has strong adhesion to metals. It can usually be fixed in about 5 minutes and reach the highest strength in one day. But also has good acid and alkali resistance, high temperature resistance and aging resistance, and can be used at the high temperature of minus 30 degrees or 150 degrees.
Application mode
Different types of structural adhesives use different methods, but they are generally the same.
1. surface treatment: roughen the parts that need to be repaired or bonded, and then clean them with cleaning agent.
2. Preparation: Mix the components A and B evenly according to the mass ratio of A:B=4: 1 or the volume ratio of 3: 1, and use them up within the specified operation time limit.
3. Coating: evenly coat the prepared glue on the surface of the adhered object.
4. Curing: curing at 20 ~ 25℃ for 24 hours or curing at 20 ~ 25℃ for 2 hours+curing at 80℃ for 2 hours can be put into use. If the temperature is low, heating or extending the curing time should be used to promote curing.
