If you are a hobbyist or model enthusiast, you probably know the importance of having the right tools and materials to bring your creations to life. One essential item that every modeller needs in their toolkit is model cement. Also known as plastic cement or styrene cement, this adhesive is specifically designed for bonding plastic models together. In this article, we will explore everything you need to know about model cement and how to use it effectively in your projects.
What is model cement?
Model cement is a specialized adhesive that is formulated to create strong bonds between plastic components. It is commonly used in the assembly of plastic model kits, such as scale models of cars, airplanes, ships, and more. Unlike regular super glue or epoxy, model cement works by chemically melting and fusing the plastic parts together, creating a seamless and durable connection.
Types of model cement
There are several types of model cement available on the market, each with its own unique characteristics and applications. The most common types include:
– Liquid Cement: This is the most popular form of model cement and comes in a bottle with a needle-point applicator tip for precise application. Liquid cement is ideal for joining small and delicate plastic parts, as it allows for easy control and prevents excess glue from seeping out.
– Tube Cement: Tube cement is a thicker and more viscous form of model cement that comes in a squeeze tube. It is best suited for bonding larger plastic components that require a stronger adhesive bond.
– Cement Pen: Cement pens are a convenient and mess-free alternative to traditional model cement bottles. They feature a felt-tip applicator that allows for precise application and are perfect for quick touch-ups and repairs.
Tips for Using model cement
To achieve the best results when using model cement, follow these tips and guidelines:
1. Prepare your workspace: Before starting any project, make sure to work in a well-ventilated area with a clean and dry surface. It is also recommended to cover your work area with a protective mat or newspaper to prevent any spills or damage.
2. Test fit the parts: Before applying the cement, dry-fit the plastic components together to ensure a proper alignment and fit. This will help you identify any gaps or adjustments that need to be made before gluing.
3. Apply a small amount of cement: Less is more when it comes to using model cement. Apply a small bead of glue along the seam of the plastic parts using the needle-point applicator or brush. Avoid using too much glue, as it can result in messy excess and weaken the bond.
4. Hold the parts together: Once you have applied the cement, hold the plastic parts together firmly for a few seconds to allow the adhesive to set and bond. Avoid moving or adjusting the parts until the glue has fully cured to prevent any distortion or misalignment.
5. Clean up excess glue: After the bond has dried, use a hobby knife or sandpaper to remove any excess glue or seam lines. You can also use a cotton swab dipped in a modeling solvent to clean up any stray glue marks or fingerprints.
Benefits of Using Model Cement
Model cement offers several advantages over other types of adhesives, including:
– Strong and durable bonds: Model cement creates a chemical fusion between plastic parts, resulting in a strong and durable bond that is resistant to impacts and vibrations.
– Seamless finish: Unlike other adhesives that leave visible glue lines, model cement creates seamless and invisible joints between plastic components.
– Quick drying time: Model cement dries quickly, allowing for faster assembly and reducing the overall project time.
