Model cement, also referred to as plastic cement or polystyrene cement, is an essential tool for anyone working with plastic scale models. Whether you are building airplanes, cars, ships, or figurines, model cement is crucial for assembling and bonding various parts together. In this comprehensive guide, we will delve into the world of model cement and provide you with everything you need to know to make the most out of this indispensable tool.
**What is model cement?**
Model cement is a special adhesive designed specifically for bonding plastic components in scale modeling projects. Unlike regular household glues, model cement is formulated to soften and bond plastic materials together, creating a strong and durable bond. The cement works by melting the surface of the plastic parts, allowing them to fuse together as it cures. This results in a seamless and invisible bond, ideal for maintaining the integrity and aesthetics of the finished model.
**Types of model cement**
There are several types of model cement available on the market, each with its own unique properties and applications. The most common types include:
1. Liquid Cement: Liquid cement comes in a bottle with a thin applicator nozzle, making it easy to apply precise amounts of adhesive to small areas. It is ideal for bonding small parts or for filling gaps between components.
2. Tube Cement: Tube cement is thicker in consistency and is typically used for larger surface areas or for bonding larger parts together. It is more viscous than liquid cement, making it easier to control and work with.
3. Solvent Cement: Solvent cement is a fast-acting adhesive that uses a powerful solvent to soften and bond plastic parts together quickly. It is ideal for quick assembly and works well on smooth plastic surfaces.
**How to Use model cement**
Using model cement effectively requires some practice and patience. Here are some steps to follow when using model cement:
1. **Prepare the Surfaces**: Before applying the cement, make sure that the surfaces to be bonded are clean and free of any dust, grease, or debris. This will ensure a strong and lasting bond.
2. **Apply a Thin Layer**: Using a brush or applicator, apply a thin layer of cement to one of the surfaces to be bonded. Be careful not to apply too much cement, as this can lead to excess glue seeping out when the parts are pressed together.
3. **Press Parts Together**: Once the cement has been applied, press the two surfaces together firmly. Hold them in place for a few moments to allow the cement to set and the bond to form.
4. **Allow to Cure**: Depending on the type of cement used, the bond may take a few minutes to several hours to cure completely. Avoid disturbing the parts during this time to ensure a strong bond.
5. **Clean Up**: Any excess cement that has seeped out between the parts can be removed using a modeling knife or sandpaper once it has dried.
**Tips for Working with Model Cement**
Here are some additional tips to help you make the most out of model cement:
1. **Ventilation**: Model cement contains strong fumes that can be harmful if inhaled. Always work in a well-ventilated area or use a respirator mask to protect yourself.
2. **Precision**: Use small amounts of cement and apply it precisely to the areas that need to be bonded. This will help prevent excess glue from ruining the model’s appearance.
3. **Experiment**: Test different types of model cement to see which works best for your specific project. Some cements may work better on certain types of plastic than others.
4. **Storage**: Store model cement in a cool, dry place away from sunlight and heat sources to prolong its shelf life and effectiveness.
**Conclusion**
Model cement is an indispensable tool for anyone involved in scale modeling projects. Its unique bonding properties make it ideal for assembling plastic components with precision and strength. By following the tips and techniques outlined in this guide, you can harness the power of model cement to create stunning and enduring scale models. Whether you are a seasoned modeler or a beginner, model cement is sure to become an essential part of your modeling toolkit. So, next time you reach for your glue, remember the versatility and strength of model cement – the unsung hero of model making.
