What You'll Learn
Preparing the surface
Before applying Loctite Epoxy Plastic Bonder, it is important to prepare the surface to ensure a strong and durable bond. Here are the steps you should follow:
Clean the surface: Use a suitable solvent to clean the plastic surface and remove any dirt, grease, or debris. You can use a cloth or brush to gently scrub the area and ensure it is free of any contaminants. Allow the surface to dry completely before proceeding.
Roughen the surface: To create a stronger bond, it is recommended to roughen the plastic surface. You can use a fine-grit sandpaper or a rotary tool with a sanding attachment to scuff the area where the adhesive will be applied. This will create micro-scratches, providing more surface area for the epoxy to grip onto.
Remove dust: After roughening the surface, make sure to remove any dust or debris generated during the sanding process. Use a tack cloth or a damp cloth to wipe down the area, ensuring it is clean and free of any residual particles.
Check compatibility: Loctite Epoxy Plastic Bonder works effectively on most plastic materials, including ABS, PVC, polycarbonate, acrylic, and more. However, it is always a good idea to test the compatibility of the adhesive with the specific type of plastic you are working with. Perform a small patch test in an inconspicuous area to ensure the epoxy bonds successfully.
Prepare the epoxy: Loctite Epoxy Plastic Bonder typically comes in a dual syringe that dispenses equal amounts of each component. Make sure to read the instructions provided with your product and follow the recommended mixing procedure to properly mix the two parts of the epoxy together.
By following these surface preparation steps, you will maximize the bonding strength and effectiveness of the Loctite Epoxy Plastic Bonder.

Mixing the adhesive
Loctite Epoxy Plastic Bonder is a two-part adhesive, meaning it consists of two separate components that must be mixed together before use. The product is designed with convenience in mind, as it comes with a dual syringe that dispenses equal amounts of each component. This ensures that you always have the perfect ratio of base to hardener, which is essential for the adhesive to cure properly.
To begin, dispense the required amount of adhesive from the dual syringe, ensuring that you have enough to cover the entire surface area of your project. The dispensed adhesive should be a uniform amber colour, indicating that the two components have been properly mixed.
Next, you will need a clean, flat surface on which to mix the adhesive. A small, disposable container, such as a plastic cup or a piece of cardboard, can be used for this purpose. Using a disposable mixing stick or a similar tool, thoroughly mix the adhesive, ensuring that the two components are fully combined. It is important to work quickly and efficiently during this step, as the adhesive has a working time of 20 to 25 minutes before it starts to cure.
Once the adhesive is mixed, you will notice that it has a thick, viscous consistency. This is intentional, as it prevents the adhesive from running or dripping during application, making it ideal for filling gaps or voids. The mixed adhesive can now be applied to the plastic surface you wish to bond, fuse, or repair.
For best results, it is recommended to follow the manufacturer's instructions for mixing and application, including any safety precautions. With its high-strength bonding ability, resistance to water and solvents, and sandable and drillable finish, Loctite Epoxy Plastic Bonder is a versatile adhesive for various plastic repair projects.

Applying the adhesive
Before applying the adhesive, ensure that the plastic surface is clean and free of any debris or residue. It is recommended to roughen smooth surfaces before application for a stronger bond.
Loctite Plastic Bonder comes in a convenient double syringe that dispenses equal amounts of each component. The two parts should be mixed in equal volumes until they are thoroughly combined. You can use a syringe or a mixing cup for this process, depending on your preference and the size of your project.
Once the adhesive is mixed, apply it to the plastic surface you wish to bond, fuse, or repair. The formula is thick and will not run or drip, making it ideal for applications where precision is required. You can use a syringe or a suitable applicator to apply the adhesive to the desired area.
For larger repairs or filling voids, you can use a large syringe without a needle to pack the mixed adhesive into the desired area. Ensure that you work quickly as the formula will start to cure and harden within 20 to 25 minutes of mixing.
After applying the adhesive, you may need to clamp or hold the bonded surfaces together for a few minutes to ensure good contact and a strong bond. The adhesive will continue to cure and harden over the next several hours, and you should allow it to cure overnight before putting the repaired item to use.

Drying and curing
Loctite Epoxy Plastic Bonder is a two-part adhesive formula that typically dries and cures within 20 to 25 minutes of application. It is designed to produce a tough, rigid, and high-strength bond. The curing time may vary depending on factors such as temperature, humidity, and the amount of adhesive used.
To ensure proper curing, it is recommended to follow the instructions on the product label and create a suitable environment. Maintain a consistent temperature and avoid extreme humidity conditions. After applying the adhesive, it is essential to allow it to cure undisturbed. Avoid handling or moving the bonded items during the curing process to prevent any disruption to the bond's strength.
While Loctite Epoxy Plastic Bonder typically cures within 20 to 25 minutes, it is advisable to allow for additional curing time for larger repairs or when joining extensive surfaces. In such cases, it is recommended to let the adhesive cure for an extended period, ensuring maximum strength and durability.
For intricate or detailed work, it is crucial to plan accordingly. The adhesive's quick curing time requires efficient time management and precise application. It is advised to work in small sections or areas to ensure control and accuracy during the bonding process.
In some cases, clamping or securing the bonded items during curing may be beneficial. This additional step can enhance the bond's strength and ensure proper alignment. However, it is important to note that Loctite Epoxy Plastic Bonder does not require clamping for everyday applications.

Sanding and drilling
Loctite Epoxy Plastic Bonder is a high-strength adhesive that can be used to sand and drill. Before you begin, ensure that you are wearing protective gear, such as a dust mask or respirator, to avoid inhaling any harmful dust particles.
Sanding is used to smooth out rough surfaces, repair damage, or fix mistakes. It is a time-consuming process, especially for larger projects, and it can be tricky for beginners. It is important to allow the epoxy to fully cure before beginning the sanding process.
There are two types of sanding: wet and dry. Dry sanding is done on a completely dry surface and is effective in removing surface imperfections. However, it creates a lot of dust, which can be hazardous if inhaled. It is important to take breaks during dry sanding to avoid generating excessive heat, which can cause the resin to melt.
Wet sanding involves moistening the surface before sanding, which helps to reduce dust and keep the temperature down. However, it can be messy, and the sanding material may clog more quickly.
For epoxy sanding, it is recommended to start with the coarsest grit and gradually increase the fineness. Using a good sander with adjustable speed, such as the Mirka Deros or Rupes LS71T Delta, can make the process more efficient. For smaller areas, a drill with a support disc can be used. It is important to clean the surface regularly with a clean cloth and acetone during the sanding process.
After sanding, the next step is polishing. For smaller surfaces, a drill attachment and sheepskin can be used, while larger surfaces may require a polishing machine with adjustable RPM. Apply an epoxy polishing compound to the pad and start at a low speed, spraying water occasionally to prevent overheating.
Drilling can be done after sanding to create holes or attachments in the epoxy surface. It is important to ensure that the epoxy is fully cured before drilling to avoid any damage.
