Tamiya Extra Thin Cement Fine Tip 40ml Bottle

Tamiya Extra Thin Cement, The Single Bottle Standard

Ask any model kit builder which glue they reach for first and the answer is almost always this bottle. Tamiya Extra Thin Cement in the 40ml single bottle format is a solvent based liquid designed specifically to bond polystyrene, the plastic used in Gunpla, aircraft, ships, armor and car kits. It does not sit on the surface like a paste. It chemically softens the top layer of the styrene so two parts flow together and cure as one continuous piece of plastic that is stronger than the original runner.

Capillary Flow for Clean Joints

The extra thin viscosity is the star feature. Hold two panel halves together, touch the fine brush to the outside of the seam, and the cement is pulled straight into the join by capillary action. You never have to pry parts apart to reach the inner surfaces. This lets you assemble a piece dry, check the fit, then weld it shut in seconds with the liquid traveling exactly where the gap is. Surfaces stay clean because the solvent hides inside the seam instead of smearing across the plastic.

The included fine tip brush lays down a thin, even line, which matters most on small pegs, thin edges and the tight interior corners of a mobile suit frame. A little goes a long way, so a single 40ml bottle typically closes many full kits before it runs low.

Seam Removal and Styrene Welding

For invisible seams, coat both mating faces, squeeze the halves together until a small bead of dissolved plastic rises along the line, and set it aside to harden. That bead is filler made from the kit plastic, so once it cures you sand it back and the seam disappears completely under primer and paint. The same welding action fills hairline gaps on weapons, thrusters and armor plates without a separate putty step.

• Single 40ml bottle, the everyday standard for styrene assembly
• Fine tip synthetic brush for controlled, precise application
• Thin solvent wicks into seams through capillary action
• Fuses polystyrene parts into one solid unbreakable joint
• Perfect for seam elimination and small gap filling
• Sets in minutes, cures fully firm within a day

Use and Storage

Keep the cap tight when not in use since the thin solvent evaporates quickly if left open. Work with good airflow and let each glued section rest until the bond reaches full strength before handling or sanding. The stable bottle shape resists tipping on a crowded bench, and the built in brush stores neatly in the neck between uses.

If you build plastic kits and want one dependable adhesive that handles closing bare plastic parts, welding seams and filling small gaps, this single bottle of Extra Thin Cement is the natural starting point for a tidy, professional finish.

One Bottle, Many Techniques

Beyond simple assembly, this cement quietly unlocks several advanced styrene techniques. Because the solvent softens plastic on contact, you can stretch heated sprue into fine threads, tack them in place with a brush of cement, and create rigging, cables or antenna wire that becomes a permanent part of the model. You can also skim the brush over a rough seam to slightly melt and reflow the surface, smoothing tool marks before you ever pick up sandpaper. Kept upright with a tight cap, one 40ml bottle serves as a bench essential that lasts through many projects and rewards careful, thin application every time.
