Adhesive VALLEJO Vallejo Ammo Slow Dry Cyanoacrylate glue, 21 g, slow-setting

VALLEJO Vallejo Ammo Slow Dry Cyanoacrylate glue, 21 g, slow-setting is a slow-curing instant adhesive formulated for precision model assembly and repair. Its extended open time allows controlled positioning of small parts and improved capillary flow into tight joints. The formula is suitable for bonding common modeling materials such as plastics, metal parts and other hobby substrates where a precise, strong bond is required without immediate fixture.

Advantages

This slow-setting cyanoacrylate provides longer working time compared with standard fast-cure glues, enabling repositioning and alignment of delicate components. It offers good penetration into narrow seams for consistent adhesion and reduces the risk of brittle joints by allowing more gradual polymerization. The 21 g bottle format gives a practical balance between volume and precision for repeated hobby use.

Suitable for

• Assembly and repair of scale models and miniatures
• Bonding small plastic parts, resin components and metal details
• Precision hobby work where controlled cure time is needed
• Filling and sealing fine gaps before finishing and painting

Key specifications

• Type: cyanoacrylate adhesive with slow-setting formulation
• Volume: 21 g bottle suitable for multiple small repairs
• Compatibility: plastics, metals, resin and common modelling substrates
• Open time: extended compared with fast cyanoacrylates to allow repositioning
• Application: capillary flow for narrow joints and fine parts

How to use

Apply the adhesive sparingly to one of the surfaces to be joined and bring parts together while the glue is still tacky. The longer open time permits precise alignment; hold or clamp parts until the joint has developed sufficient strength. For best results, ensure mating surfaces are clean and dry. Use minimal amounts to avoid excess squeeze-out and allow full cure before sanding or painting.

Usage recommendations

Work in a well-ventilated area and avoid skin or eye contact. Store the bottle upright in a cool, dry place and seal tightly after use to prolong shelf life. Consider using an activator or accelerator only if faster cure is required for specific tasks; otherwise rely on the slow-setting formulation for controlled assembly.
