How to deal with epoxy AB adhesive not fully cured?
Epoxy AB adhesive is not fully cured, you can take the following measures to deal with:
First, check and adjust the ratio
Confirm the accuracy of the ratio: epoxy AB adhesive consists of two parts, epoxy resin and curing agent, if the ratio of the two is not accurate, it may lead to incomplete curing. Therefore, the first thing to check is whether the accurate proportioning has been carried out in accordance with the recommended proportion in the product specification.
Re-mixing: If you find that the proportioning is wrong or the mixing is not sufficient, you can re-mix the adhesive resin and curing agent to ensure accurate proportioning and careful mixing.
Second, adjust the curing conditions
Increase the temperature: the curing speed of epoxy AB adhesive is closely related to the temperature. If the ambient temperature is too low, it may lead to slow curing speed or even stop. You can try to increase the ambient temperature, the use of heating equipment (such as hot air guns, ovens, etc.) to accelerate the curing process. However, it should be noted that the heating temperature should not exceed the recommended range in the product specification to avoid damaging the material or affecting the curing effect.
Maintain appropriate humidity: High humidity may also affect the curing speed and effect of epoxy AB adhesive. Ensure that the bonding surface is dry and avoid use in an environment with high humidity.
Third, extend the curing time
Give enough time: the curing time of epoxy AB adhesive may vary depending on the product model, ambient temperature and humidity and other factors. If the curing time is insufficient, it may result in the glue not fully cured. Sufficient curing time can be given according to the recommendations in the product manual to allow the glue to fully react and cure.
Fourth, check the storage conditions
Check the storage environment: the storage conditions of epoxy AB adhesive will also affect its curing ability. If the glue is exposed to high temperature, humidity or direct sunlight, it may lead to inactivation of the hardener or aging of the gum resin. Therefore, make sure that the epoxy AB adhesive is stored in appropriate temperature and humidity conditions, and avoid storing it in undesirable environments.
- Replacement of products
Consider product quality: If the above methods are unable to solve the problem, may be the epoxy AB adhesive itself has quality problems. At this time, you can consider replacing other brands of epoxy AB adhesive, and choose reliable quality, good reputation of the product.
Sixth, consult a professional
Seek professional help: If the above measures still can not solve the problem, it is recommended to consult professional and technical personnel or glue suppliers. They can provide more specific solutions and suggestions according to the specific situation.
In summary, to deal with the problem of epoxy AB adhesive is not fully cured need to start from a number of aspects, in the use of the process, we must carefully read the product manual, in accordance with the recommendations of the manual to operate, and pay attention to the observation of the curing of the glue. If the problem still can not be solved, it is recommended to consult a professional in time to get help.
