TAMIYA Extra-Thin Cement 40ml Quick-Setting TAM87182 Review (2026)

Who benefits from a faster cement

Modelers assembling kits with lots of small, fiddly parts, like cockpit interiors, figure accessories or multi part suspension, are the main audience for this cement. Because it dries roughly four times faster than Tamiya's standard Extra Thin Cement, it saves time spent holding parts steady while a joint sets, which adds up over a build with dozens of small glue points. Builders who like to test fit and adjust parts after applying glue should be more cautious, since the fast set does not leave much room to correct a misaligned joint once the cement has been applied. For straightforward, well test fitted assemblies, the speed is a clear time saver.

What is in the bottle and how it behaves

The cement ships in a 40ml bottle with Tamiya's thin brush cap applicator, and the formula is a highly liquid solvent style plastic cement that is drawn into a seam by capillary action rather than applied like a thick glue. Typical set time is under 10 seconds, compared with the slower cure of the standard Extra Thin Cement, which makes it useful when a part needs to be handled again almost immediately. The thin viscosity lets it flow into narrow gaps and tight corners where a thicker cement would leave visible excess, and it welds styrene plastic by melting the surfaces together rather than just bonding them.

Using it without ruining a joint

Because the working time is short, the best approach is to dry fit and align parts fully before touching the brush tip to the seam, then let capillary action pull the cement through the joint. The bottle's fine brush applicator helps control how much cement reaches a seam, which matters more here than with slower cements since there is little time to wipe away excess before it sets. The maker does not recommend this quick setting formula for larger gaps that need gap filling cement, or for elastomer parts such as vinyl tank tracks, where the fast acting solvent can make the material brittle. Good ventilation is worth keeping in mind given the solvent odor.

How it compares with other cements

The standard Tamiya 87038 Extra Thin Cement remains the safer choice for beginners or complex multi part assemblies, since its slower set gives more time to reposition parts before the joint locks. Mr. Cement SP from Mr. Hobby offers a comparably strong bond with its own applicator brush, while GSI Creos Mr. Cement S is a thinner, slower drying alternative closer to Tamiya's original formula. Against Tamiya's own thicker 20ml Plastic Cement, this quick setting Extra Thin Cement is far less forgiving of gaps but noticeably faster to work with on tight, well fitted seams.

Verdict for most builders

With our score of 8.9 out of 10, this cement rewards builders who plan their glue ups and test fit parts before applying it, turning what would be a held in place wait into a near instant bond. It is not the right first cement for someone still learning to judge fit and alignment, since mistakes set almost as fast as good joints do. Modelers already comfortable with solvent cements who want to speed up assembly sessions, especially on kits with many small interior or detail parts, are the ones who will get the most value from keeping a bottle on the bench.
