Model cement, also known as plastic cement or polystyrene cement, is an essential tool for any enthusiast or hobbyist who works with plastic models. Whether you’re building model airplanes, cars, ships, or even miniature figurines, model cement is a must-have adhesive that ensures strong and durable bonds between plastic parts. In this article, we will explore everything you need to know about model cement and how to use it effectively.
What is model cement?
Model cement is a specialized adhesive designed specifically for bonding plastic components in model kits. Unlike regular glue, which can leave unsightly marks or gaps between parts, model cement forms a strong chemical bond that welds the plastic parts together. This creates a seamless and invisible bond that is essential for achieving a professional-looking finish on your models.
Model cement typically comes in liquid form and is applied using a small brush or applicator. As the cement dries, it softens and partially melts the plastic parts, allowing them to fuse together and create a strong bond. This process is known as solvent welding, and it is what sets model cement apart from traditional adhesives.
Types of model cement
There are several different types of model cement available on the market, each with its own unique properties and advantages. The most common types of model cement include:
– Liquid Cement: Liquid model cement is the most popular and widely used type of model cement. It comes in a small bottle with a built-in brush applicator, making it easy to apply and control. Liquid cement is ideal for bonding small or intricate parts, as it allows for precise application and dries quickly.
– Tube Cement: Tube model cement is another popular option, especially among experienced model builders. Tube cement is thicker and more viscous than liquid cement, making it ideal for bonding larger or heavier parts. Tube cement is often used for structural bondings, such as joining the fuselage of an airplane or the hull of a ship.
– Cement Pen: Cement pens are a convenient and mess-free alternative to traditional model cement. These pens feature a fine tip applicator that allows for precise application of cement in tight spaces or delicate areas. Cement pens are ideal for touch-ups or repairs and are a great addition to any model builder’s toolbox.
How to Use model cement
Using model cement effectively requires a few simple steps to ensure a strong and durable bond between plastic parts. Here is a step-by-step guide on how to use model cement:
1. Prepare the parts: Before applying model cement, make sure to clean and dry the surfaces of the plastic parts that you will be bonding. Remove any excess flash or debris from the parts to ensure a clean and secure bond.
2. Apply the cement: Using a small brush or applicator, apply a thin layer of model cement to one of the surfaces that you will be bonding. Avoid using too much cement, as this can lead to excess glue and messy joints.
3. Join the parts: Carefully align the plastic parts and press them together firmly to create a strong bond. Hold the parts in place for a few seconds to allow the cement to soften and weld the parts together.
4. Let it dry: Allow the model cement to dry completely before handling or moving the bonded parts. The drying time may vary depending on the type of cement used, so refer to the manufacturer’s instructions for specific drying times.
5. Clean up: Once the cement has dried, clean up any excess glue or residue using a damp cloth or cotton swab. Make sure to remove any fingerprints or smudges to maintain a clean and professional finish on your model.
Tips and Tricks for Using Model Cement
– Work in a well-ventilated area: Model cement can emit strong fumes, so it’s important to work in a well-ventilated space to avoid inhaling the fumes. Open a window or use a fan to keep the air circulating while working with model cement.
– Use sparingly: When applying model cement, less is more. Avoid using too much cement, as this can lead to messy joints and excess glue. A thin layer of cement is usually sufficient to create a strong and durable bond between plastic parts.
– Experiment with different types: Depending on the size and complexity of your model kit, you may find that certain types of model cement work better than others. Experiment with different types of cement to find the one that suits your needs best.
In conclusion, model cement is an essential tool for any model builder looking to achieve professional-looking results. By understanding the different types of model cement available and following the proper techniques for application, you can create strong and durable bonds between plastic parts that will stand the test of time. So the next time you embark on a new model building project, be sure to have model cement on hand to ensure a successful and satisfying build.
