When you're using AB glue for metal bonding, you may run into a problem: your glue isn't fully cured. This may be due to a number of reasons, so let's find out.
First of all, we need to understand the curing process of AB glue. AB glue is made by mixing two components, which are glue A and glue B. When these two components are mixed, they undergo a chemical reaction that creates a curing effect. However, this process requires a certain amount of time and proper conditions.
Here are a few reasons why metal AB adhesives may not cure completely:
Wrong mixing ratio: When mixing glue A and glue B, if the ratio is incorrect, it may cause the glue to not cure properly. In general, it is very important to mix in the right proportions.
Uneven mixing: If the two components are mixed unevenly, then the curing effect of the glue will also be affected. Make sure that both components are well stirred during the mixing process.
Temperature problem: Temperature also has an impact on the curing speed and effect of AB adhesive. If the ambient temperature is too low, it may cause the glue to cure slower;If the temperature is too high, it may allow the glue to cure too quickly. Therefore, it is very important to choose the right temperature for operation.
Humidity problem: High humidity may also affect the curing effect of metal AB adhesive. Therefore, care should be taken to keep the environment dry while operating.
Improper metal surface treatment: If the metal surface is not cleaned or properly treated, it may affect the adhesion and curing effect of AB adhesive. Make sure the metal surface is clean and dry before bonding.
Insufficient glue usage: If you are using insufficient amount of metal AB glue, then you may not be able to form sufficient bond strength. When operating, make sure to use enough glue.
Incomplete chemical reaction: The chemical components in metal AB glue take a certain amount of time to fully react after mixing, and if the waiting time is insufficient, it may lead to incomplete curing of the glue.
