What You'll Learn
Opening the bottle
If your bottle of Tamiya plastic cement won't open, there are a few things you can try. One suggestion is to place the whole bottle under very warm water for five to ten minutes. This should help expand the cap, making it easier to open. You can also try running just the cap under warm or hot water, as this may be enough to expand it and allow you to remove it.
If the cap is too tight, you can try using long-nose pliers to open the bottle. This may be easier if you have already tried warming the cap, as the heat will have made the plastic slightly softer.
Another user has suggested that their bottle had a white foam-like ring seal in the cap that was prone to falling out. Check to see if your bottle has this seal, as it may have dropped out and you didn't notice.
Once you have the bottle open, place it on your desk. Grasp the bottle with your non-dominant hand and the twist-top with your dominant hand. Turn your dominant hand in a counter-clockwise motion until the top moves free of the bottle.

Applying the cement
Tamiya Extra Thin Cement is a low-viscosity, watery-like welding solvent with moderate seeping and
To apply the cement, first carry the bottle to your desk and place it down. Then, grasp the bottle with your non-dominant hand and use your dominant hand to twist the top in a counter-clockwise motion until it comes free. Move the application brush to one of the parts that is to be joined and brush on the solution. If you need more solution, dip the brush back into the bottle. Apply the solution to the second part, then hold the parts together for a few seconds.
The pointed applicator tip makes it easy to put the cement where desired. The thin cement flows smoothly between the gaps of the fitted parts by capillary action. Tamiya Extra Thin Cement is ideal for gluing plastic parts into the desired position while holding them in place together.
When cementing track links and sections, allow the cement to skin over so it is not tacky for ease of assembly on road wheels, return rollers, idler wheels, and sprockets.

Bonding the plastic
Tamiya Extra Thin Cement is a popular choice for bonding plastic in model kits. It is an acetone-based plastic glue that melts the plastic parts and forms a bond as they dry. It is important to note that Tamiya Extra Thin Cement should be used in a highly ventilated area and away from any high heat or open flames.
To use Tamiya Extra Thin Cement for bonding plastic, follow these steps:
- Carry the bottle to your work area and place it on your desk.
- Hold the bottle with your non-dominant hand and grasp the twist top with your dominant hand.
- Turn the twist top counter-clockwise to open the bottle.
- Use the brush on the reverse side of the cap to apply the cement to one of the parts that need to be joined.
- Brush the solution onto the other part or dip it into the bottle for more solution if needed.
- Hold the parts together for a few seconds.
- Allow the cement to dry and cure fully, which typically takes around 24 hours.
It is important to work quickly as Tamiya Extra Thin Cement has a working time of only 1-2 minutes. Additionally, be cautious when handling the cement as it can cause skin irritation and serious eye damage. Always refer to the Material Safety Data Sheet (MSDS) provided by the manufacturer for specific safety information and emergency contact details.
Tamiya Extra Thin Cement is available in different formulations, such as the dark green cap for general-purpose plastic cement and the lime green cap for quick-setting cement. The dark green cap variety has low viscosity and moderate seeping and capillary action, making it ideal for parts that friction fit, snap fit, or have location markers. The lime green cap variety has an even lower viscosity than water, resulting in higher joint and seam penetration.

- Skin and Eye Contact: This product can cause skin and eye irritation. Avoid direct skin contact by wearing gloves. If it comes into contact with your skin, wash the affected area with soap and water. In case of eye exposure, immediately flush your eyes with water for at least 15 minutes and seek medical attention if irritation persists.
- Spill Precautions: In the event of a spill, do not panic. Absorb the liquid with an inert material (e.g., sand or absorbent pads) and place it in a chemical waste container. If a significant amount is spilled, notify the fire brigade and police, as they have the necessary equipment to handle chemical spills.
- Food and Drink: Avoid consuming food, alcohol, or any beverages during use. Wash your hands thoroughly before eating or drinking to prevent accidental ingestion of the product.
- Clean Work Area: Always clean your work area after using Tamiya Extra Thin Cement. Use appropriate cleaning agents, such as isopropyl alcohol, to remove any residual cement from surfaces and tools. Remember that even empty containers can pose a hazard, so handle them with care and dispose of them properly.
- Allergies: Some individuals may develop allergies or sensitivities to the cement or its vapors. If you experience symptoms like coughing, a runny nose, sneezing, or flu-like symptoms, discontinue use and seek medical advice.
- Child Safety: Keep Tamiya Extra Thin Cement out of the reach of children and supervise them if they are using it. Educate them about the potential hazards and the importance of following safety protocols.

Alternative products
Tamiya Extra Thin Cement is an acetone-based plastic glue. While it is a popular product, some users have reported developing allergies to it, with symptoms such as coughing, a runny nose, and occasional sneezing. If you are looking for alternative products to use, there are several options available.
One alternative is to use a different type of glue, such as CA SuperGlue, which is often available in craft shops. However, it is important to note that super glue is not a "do-everything" glue and may not be suitable for all types of plastic model kits. When working with super glue, it is also important to be cautious as it can be tricky to apply due to its fast-setting nature.
Another option is to explore plastic solvent glues, which can be ordered online. These glues come in thin and thick consistencies, making them suitable for different types of joints. Thick cement, for example, provides extra strength for big, heavy, and long-curing joints.
Additionally, you may consider MEK (Methyl Ethyl Ketone) as an alternative, especially if you are an experienced user. While it can be risky for beginners, it is safe to use as long as it is not ingested, inhaled, or played with.
Limonene is another option to consider, as it is a naturally derived and less toxic type of cement that works with non-polystyrene plastics.
Finally, for gluing brass, resin, wire, and styrene, cyanoacrylate (CA) or super glue can be effective. However, similar to other types of super glue, it can be challenging to apply due to its fast-setting nature.
