model cement, also known as plastic cement or styrene cement, is an essential tool for any model builder. Whether you’re working on scale models of cars, planes, ships, or trains, model cement is a must-have for securely bonding plastic parts together. In this article, we’ll cover everything you need to know about model cement, including how it works, different types available, and tips for using it effectively.
How does model cement work?
model cement is a type of solvent glue that works by softening and partially melting the plastic surfaces of the parts you’re bonding together. When the solvent evaporates, the plastic hardens again, creating a strong and durable bond. This process is often referred to as “welding” the plastic parts together, as it essentially fuses them into one solid piece.
Different types of model cement
There are several different types of model cement available, each with its own unique properties and applications. The most common type is liquid plastic cement, which comes in a bottle with a brush applicator. This type of cement is easy to apply and dries quickly, making it ideal for most modeling projects.
Another popular type of model cement is plastic cement in tube form. This type of cement is thicker than liquid cement and is better suited for bonding larger pieces or filling gaps between parts. Tube cement is also less prone to evaporating quickly, making it a good choice for beginners or for projects that require more time to assemble.
There are also specialty model cements available, such as super glue or epoxy, which are designed for specific materials or applications. These types of cement can be useful for bonding materials other than plastic, such as metal or wood, or for creating extra-strong bonds in high-stress areas of your model.
Tips for using model cement effectively
To ensure the best results when using model cement, follow these tips for effective application:
1. Clean the surfaces: Before applying the cement, make sure to clean the surfaces of the parts you’re bonding together. Remove any mold release agents, oils, or dirt that could prevent the cement from adhering properly.
2. Apply sparingly: A little goes a long way when it comes to model cement. Apply a thin, even layer of cement to one of the surfaces you’re bonding, then press the parts together firmly for a few seconds to create a strong bond.
3. Use in a well-ventilated area: model cement can give off fumes that can be harmful if inhaled in large quantities. Make sure to use the cement in a well-ventilated area or wear a mask to protect yourself from the fumes.
4. Consider using a glue applicator: If you’re working on small or intricate parts, consider using a glue applicator to apply the cement more precisely. This can help prevent excess cement from smearing onto other parts of your model.
5. Allow time to dry: Model cement dries quickly, but it’s important to give it enough time to fully cure before handling your model. Depending on the type of cement you’re using, this can take anywhere from a few minutes to a few hours.
In conclusion, model cement is an essential tool for model builders of all skill levels. By understanding how it works, the different types available, and following these tips for effective application, you can create strong and durable bonds in your models that will stand the test of time. Whether you’re a beginner or a seasoned pro, model cement is a must-have for bringing your scale models to life.
