Methylacrylate adhesive offers unmatched strength, a fast cure time, and can bond dissimilar objects. It is widely used in marine, general industrial applications, and assembling automotive for exceptional performance. However, these adhesives also present issues if not applied correctly. Therefore, understanding the root causes of these problems and addressing them saves time and resources. Here is your guide to troubleshooting the most common issues.

Poor adhesion

The most prominent issue while using the strongest epoxy for metal is poor adhesion. In this case, the adhesion fails to bond securely on surfaces. It happens primarily due to inadequate surface preparation. Furthermore, dust, oils, and moisture interfere with the bonding process.

The solution: Always follow the surface prep guidelines, including:

• Cleaning surfaces with isopropyl alcohol
• Lightly abrading smooth surfaces
• Ensure a dry surface before adhesive application.
• Adding a primer for optimal adhesion

Incomplete cure or soft bond lines

Does your adhesive remain soft or gummy after the curing time? It is a result of improper mixing of the components, or there is a possibility of a low ambient temperature for proper curing.

The solution: Ensure the adhesive is mixed in the correct proportion, if you are using a manual or cartridge dispensing system. Furthermore, check if the base and activator are even and consistently combined. If you are working in cold conditions, use a product designed specifically for low-temperature curing or allow the adhesive to cure fully.


Excessive odor or fumes

Methacrylate has a strong odor due to the volatile monomers. Therefore, its fumes can become overwhelming in confined or poorly ventilated spaces. 

The solution:

Always step into a well-ventilated space and wear PPE such as a respirator if required. Furthermore, choosing a low-odor or low-VOC formulation also reduces this issue.

In a nutshell, identifying and addressing these issues helps troubleshoot them early on. Moreover, users who want reliable bonds and long-lasting results, taking extra care in preparation goes a long way.
