Humbrol Poly Cement Tube (12ml) AE4021

The Humbrol Poly Cement (AE4021) is a trusted plastic adhesive, specially formulated for bonding polystyrene and ABS plastic components in model kits. Supplied in a compact 12ml tube, this solvent-based cement is easy to apply and provides a strong, long-lasting bond — essential for assembling scale models, figures, and other hobby projects that require a secure fit and precision alignment.

This adhesive works by slightly melting the plastic surfaces it comes into contact with, creating a welded bond as the solvent evaporates. This results in a seamless join that is both clean and durable. Ideal for bonding fuselage halves, tank hulls, vehicle parts, or small detail components, it allows for some repositioning before fully curing — giving you time to achieve a perfect fit.

The nozzle applicator provides controlled dispensing, allowing you to apply the glue exactly where it’s needed. It’s best suited for internal joints and invisible seams where strength is key and external appearance matters. Once set, the bonded parts can be sanded, painted, and detailed just like any other area of the model.
