ABS Plastic: Most Gunpla kits use ABS for durability, flexibility, and ease of painting
ABS plastic stands as the backbone of most Gunpla kits, chosen for its unique blend of durability, flexibility, and paintability. Unlike brittle materials that crack under stress, ABS can withstand the rigors of assembly, posing, and even accidental drops, making it ideal for intricate Gundam models. Its slight give allows for snap-fit construction without compromising structural integrity, ensuring that joints remain secure yet adjustable. This resilience is particularly crucial for larger-scale models or dynamic poses that demand both strength and stability.
For hobbyists, the ease of painting ABS is a game-changer. Its surface accepts primer and paint with minimal preparation, unlike smoother plastics that require extensive sanding. A light scuff with 400-grit sandpaper and a coat of Tamiya Surface Primer (available in gray or white) create an ideal base for acrylics or enamels. For best results, apply thin layers of paint, allowing each coat to dry completely before handling. This method not only preserves detail but also prevents chipping, ensuring your Gundam retains its custom finish through repeated displays or adjustments.
Comparatively, ABS outperforms alternatives like PVC or polystyrene in both function and finish. While PVC offers flexibility, it lacks the structural strength needed for larger kits, often warping under its own weight. Polystyrene, though lightweight, is prone to cracking and difficult to paint without heavy preprocessing. ABS strikes a balance, combining the best of both worlds—it’s sturdy enough for complex builds yet forgiving enough for beginners to work with. Its compatibility with cement and glue also allows for permanent modifications, a feature absent in purely snap-fit designs.
One practical tip for working with ABS is to use a hairdryer or heat gun to soften joints for precise positioning. Apply low heat for 5–10 seconds, then gently bend or adjust the part into place. Avoid overheating, as ABS can warp if exposed to temperatures above 200°F (93°C). For repairs, ABS cement (such as Plastruct) melts the plastic slightly, creating a seamless bond stronger than traditional glues. Always work in a well-ventilated area when using chemicals, and consider wearing gloves to avoid skin irritation.
In essence, ABS plastic is the unsung hero of Gunpla kits, enabling both durability and customization. Its properties cater to builders of all skill levels, from those assembling their first HG kit to seasoned modelers crafting intricate MG or PG masterpieces. By understanding its strengths and proper handling techniques, hobbyists can maximize the potential of their Gundams, ensuring they remain both functional and visually stunning for years to come.
