Humbrol AE2720 Poly Cement, Clear

Product Overview

Humbrol AE2720 Poly Cement, Clear is a precision solvent‑based adhesive specifically engineered for plastic model kits and hobbyist projects. It delivers a fast‑setting bond with minimal viscosity, allowing for clean application and precise alignment of small components.

Key Features

• Low Viscosity Formula: The clear liquid flows easily into tight gaps, ensuring a uniform spread without excess residue.
• Rapid Drying Time: Bonds are typically achieved within seconds to minutes, reducing waiting periods during assembly.
• Clear Finish: Once cured, the adhesive remains virtually invisible, preserving the aesthetic integrity of models.
• Versatile Plastic Compatibility: Ideal for a wide range of thermoplastics such as ABS, PVC, and polycarbonate commonly used in model kits.
• Compact 20 ml Tube: The small bottle size is convenient for on‑the‑go use and minimizes waste during detailed work.

Application Guidelines

For optimal results, follow these steps:

1. Surface Preparation: Clean the parts to be bonded with a mild solvent or alcohol to remove oils and dust.
2. Apply Sparingly: Use a fine brush or the tube tip to deposit a thin film of adhesive on one surface. Excess can cause dripping and slow drying.
3. Align Carefully: Position the parts quickly, as the glue sets rapidly. Hold them together for a few seconds to ensure full contact.
4. Allow Curing: Let the assembly sit undisturbed for at least 30 seconds; full strength is typically achieved within minutes.
5. Clean Up Residue: If any adhesive seeps out, wipe it with a damp cloth before it dries.

Performance Characteristics

The chemical composition of the AE2720 provides a balance between adhesive strength and flexibility. It resists cracking under minor flexing, making it suitable for parts that may experience slight movement. The solvent base ensures quick evaporation, leaving behind a durable bond.

Strength & Durability

When tested on standard ABS panels, the cured adhesive exhibits tensile strengths comparable to other high‑grade plastic cements, while maintaining a smooth finish that does not interfere with paint or decals.

Safety Considerations

As a solvent‑based product, it should be used in well‑ventilated areas. Avoid prolonged skin contact and keep away from open flames during application.

Common Use Cases

• Model Aircraft & Cars: Attaching wings, fuselage panels, or body kits where a clear bond is essential.
• Miniature Figures: Joining plastic limbs or accessories without visible glue lines.
• Scale Model Kits: Fitting intricate parts such as propellers, antennae, and small structural elements.
• Prototype Development: Quick assembly of prototype components for testing form and function.

Storage & Shelf Life

Keep the tube tightly capped in a cool, dry place. When stored properly, the adhesive retains its effectiveness for several years, making it a reliable choice for long‑term hobby projects.

Conclusion

Humbrol AE2720 Poly Cement, Clear stands out as a dependable, fast‑acting solvent glue that delivers clean, strong bonds across a variety of plastic materials. Its low viscosity and clear finish make it the adhesive of choice for hobbyists who demand precision and aesthetic quality in their model assemblies.
