X-21 Flat Base, acrylic paint, 10 ml bottle

X-21 Flat Base is an X-Acrylic paint for plastic model building, supplied in a 10 ml bottle for controlled bench use on smaller painting jobs, detail areas and measured paint mixes. The compact bottle size keeps the amount manageable when a project calls for precise handling rather than large-volume coverage. The paint belongs to the X-Acrylic range and is identified as X-21 Flat Base, making it easy to match within an established hobby paint system. The safety data names it as a liquid acrylic resin special paint and lists a density of 1.0 g/ml at 23 °C. The same data also states a boiling range of 80 to 120 °C and a flash point of 31 to 33 °C. For workshop handling, the label information specifies use in well-ventilated areas and eye protection during application. On the workbench, the 10 ml format suits careful dispensing into palettes, mixing cups or small paint trays for scale modelling sessions. It also stores efficiently alongside other coded colours in the X-Acrylic line, helping keep paint selection orderly during ongoing build, finishing and touch-up work.
