Loctite offers a range of adhesives for bonding plastic, including flexible plastics, polyethylene, polypropylene, PVC, polystyrene, and other harder plastics. However, there are mixed reviews about its effectiveness, with some users reporting that Loctite eats into the plastic, making it brittle and prone to breaking. To achieve the best results with Loctite on plastic, it is crucial to follow the instructions, prepare the surfaces, and allow adequate curing time. While Loctite may work for certain plastic applications, alternative adhesives like CA glue, Tamiya Thread Locker, and Vibra-Tite are also suggested for plastic bonding to avoid the potential issues associated with Loctite.

Loctite's Super Glue All Plastics
Loctite Super Glue All Plastics is a two-part system that can be used to bond hard and soft plastics. It is a permanent bonding solution for plastic surfaces. The two parts consist of an agent and surface activator, and an adhesive. The activator helps to roughen the surface of the plastic, creating a stronger bond. This product is ideal for use with polyethylene and polypropylene surfaces, which are usually difficult to bond.
Loctite Super Glue All Plastics is a strong adhesive that sets in seconds and dries transparently. It is resistant to water, most chemicals, and even freezing temperatures. The curing time is quick, but it is important to follow the product's instructions for the best results. The product directions will specify how long to clamp, tape, or elastic pieces together while the glue dries.
When using this product, it is important to sand the surface of the plastic to create a rough surface for the glue to bond to. This can be done with 120 to 200 grit sandpaper, steel wool, or emery cloth. The glue can then be applied with a small paintbrush or the tip of a needle for precise, detailed application.
Loctite Super Glue All Plastics is a strong and effective adhesive for bonding plastic surfaces. However, it is important to note that Loctite has been known to damage plastic substrates, causing brittleness and degradation. This is especially true when using Loctite to adhere metal screws to plastic, as the strong compound can quickly damage the surrounding plastic. Therefore, it is crucial to understand the limitations and potential risks of using this product.

Once applied, the parts should be sealed tightly with clamps, tape, or elastics to ensure a firm hold while the glue dries.
While Loctite Plastic Bonder is a strong adhesive, it may not be suitable for all types of plastic. Some users have reported that Loctite can degrade plastic substrates, making them brittle and prone to breaking. This is especially true when using Loctite to adhere metal screws to plastic, as the strong compound can quickly damage the surrounding plastic. Therefore, it is important to understand the limitations and potential risks of using Loctite on plastic before application.

Loctite's Glue Remover
Loctite offers a range of adhesives and glues for various purposes, including plastic bonding. However, it is important to note that Loctite is not recommended for adhering metal screws to plastic as it can damage the plastic substrate. The strong compound can cause fumes and degrade the surrounding plastic, making it brittle and prone to breaking.
If you need to remove Loctite super glue or adhesives from surfaces, Loctite provides guidance on how to do so safely and effectively. Here is a step-by-step guide on removing Loctite super glue:
Loctite Super Glue Removal Process:
Step 1: Surface Application
- Apply acetone to a cloth and dab it onto the dried super glue.
- Wait for around 10 minutes to ensure the acetone is not too harsh for the surface.
Step 2: Scrubbing
- Gently scrub the glue residue with a soft-bristled toothbrush, adding more acetone as needed.
- Proceed slowly and carefully to avoid damaging the surface.
Step 3: Residue Removal
- Once the glue stain is removed, dampen a clean cloth with water and dab the area to neutralize any remaining acetone.
- You can also use warm, soapy water to remove residue, especially on plastic surfaces, as it is gentler and less likely to cause damage.
Step 4: Drying
Finally, use another clean cloth to dry the surface thoroughly.
Additional Tips:
- For metal surfaces, try acetone-based nail polish remover or a soak in a 2:1 mix of water and white vinegar for 30 minutes.
- Commercial stain removers can be effective for fabric, but always test on a small area first to avoid damage.
- Vinegar is a powerful and safe cleaner for removing residue from plastic surfaces.
- A simple damp cloth can be effective for removing residue from wood, but be cautious with paper-based stickers as they may stick more firmly when wet.
