High Density Cement

Tamiya High Density Cement: precision and grip in every joint

The Tamiya High Density Cement (ref. TA87012) is the go-to liquid adhesive for those working with polystyrene models and demanding absolute control in application. Its high-density formula allows for better management of the amount of product deposited, reducing the risk of overflow and unwanted marks on delicate parts.

Main features

• Format: 20 ml bottle with integrated brush applicator in the cap.
• Type: high-density liquid cement for polystyrene.
• Initial resistance time: approximately 5 minutes.
• Full cure: 24 hours.
• Brush applicator: included in the cap for fine and controlled dosing.

Applications and compatibilities

This cement is specifically designed for plastic polystyrene models, the predominant material in static model kits, figures, and dioramas. It is also compatible with other materials commonly found on the modeller's workbench: wood, card, and paper.

Incompatible materials: Styropor®, polyethylene (PE), and polypropylene (PP). If you are working with these materials, you will need a specific adhesive for each substrate.

Application tips

• Clean the surfaces well before gluing: they must be dry, free of dust, and any grease or release agent residues.
• Apply a thin layer of cement on one of the sides to be joined.
• Join the pieces and hold them briefly while the adhesive takes effect.
• If the glue overflows, do not clean it while wet: wait for it to harden completely and then carefully remove it.
• For very thin or delicate plastic parts, reduce the amount of product applied to avoid deformation.

Ideal for…

This cement fits perfectly into the daily routine of the modeller working with static model kits of any scale, as well as in the construction of dioramas and the preparation of bases with mixed elements (wood, card, paper). Its integrated brush makes it especially useful when gluing small parts or in hard-to-reach areas where precision makes the difference between a clean finish and one with excess glue.

Considerations

Like all polystyrene cements, it works by slightly dissolving the surface of the plastic to create a molecular bond. This means that the resulting joint is very strong, but also that mistakes are difficult to correct once the adhesive has started to act. Work calmly, apply a small amount of product, and adjust the pieces quickly.

Store the bottle tightly closed and upright to preserve the viscosity of the product and prevent the brush from drying out between modelling sessions.

Frequently asked questions

What is the difference between normal Tamiya Cement and High Density?

The high-density version has a higher viscosity, making it easier to apply a more controlled layer and reducing the tendency of the liquid to spread by capillarity. It is especially useful in joints where it is necessary for the adhesive to stay in place before the pieces are joined.

Can I use this cement with ABS plastic?

The Tamiya High Density Cement is formulated for polystyrene. ABS is a different material and, while it may sometimes adhere, the results are not consistently reliable. There are specific adhesives for ABS that offer greater reliability.

How long does it take to dry completely?

The glue reaches functional strength in about 5 minutes, enough to release the pieces without them moving. However, final strength is not achieved until approximately 24 hours later, at which point the joint will be at its maximum hardness.

Can it be used on figures and dioramas as well as on models?

Yes. As long as the pieces are made of polystyrene, wood, card, or paper, the cement works without issues. It is a common tool in the construction of dioramas where various materials are combined.

What should I do if I have leftover glue on the surface?

Do not attempt to clean it while it is wet, as you would spread the product and could damage the plastic or surrounding paint. Wait for it to harden completely and then carefully remove it, for example with a blade or fine-grit sandpaper.
