When it comes to constructing models, one essential tool that every hobbyist needs in their arsenal is model cement. Also known as plastic cement or styrene cement, this adhesive is specifically designed for bonding plastic parts together. Whether you’re assembling plastic model kits, building miniature dioramas, or crafting scale models, having a reliable and high-quality model cement can make all the difference in the final outcome of your project.
In this article, we will delve deeper into the world of model cement, discussing its different types, uses, application techniques, and tips for achieving the best results with this indispensable tool.
Types of model cement
There are several types of model cement available on the market, each formulated for specific purposes and materials. The most common types include:
1. Polystyrene cement: Also known as liquid cement or thin cement, this type of model cement is ideal for bonding polystyrene plastic parts. It works by slightly melting the plastic surfaces, allowing them to fuse together to create a strong bond. Polystyrene cement is perfect for assembling plastic model kits, such as model airplanes, cars, ships, and military vehicles.
2. Solvent-based cement: This type of model cement contains volatile solvents that evaporate quickly, creating a strong bond between plastic parts. Solvent-based cement is suitable for bonding different types of plastics, including ABS, acrylic, and styrene. It is commonly used for constructing scale models and dioramas.
3. Epoxy cement: Epoxy model cement consists of a two-part adhesive system that requires mixing before application. Once mixed, epoxy cement forms a durable and waterproof bond, making it suitable for outdoor display models and projects that require extra strength.
Application Techniques
Before applying model cement, it is essential to prepare the plastic surfaces by removing any mold release agents, dirt, or grease that may interfere with the bonding process. To do this, use a mild soap or detergent to clean the parts thoroughly and allow them to dry completely before assembly.
When applying model cement, follow these steps for best results:
1. Apply a small amount of cement to one of the plastic surfaces using a fine brush or applicator. Avoid using too much cement, as this can cause the adhesive to ooze out and create a messy bond.
2. Press the two plastic parts together firmly, ensuring that the cement spreads evenly between the surfaces. Hold the parts in place for a few seconds to allow the bond to set.
3. Wipe off any excess cement with a damp cloth or cotton swab before it dries. This will help prevent unsightly marks or residue on the finished model.
4. Allow the cement to cure completely according to the manufacturer’s instructions before handling or moving the assembled parts. This may take anywhere from a few minutes to several hours, depending on the type of cement used.
Tips for Using model cement
To achieve professional-looking results with model cement, consider the following tips and tricks:
1. Work in a well-ventilated area when using solvent-based model cement, as the fumes can be strong and potentially harmful if inhaled in large quantities.
2. Use a plastic cement applicator with a fine tip for precise application and to minimize excess cement buildup.
3. Experiment with different cement types and brands to find the one that works best for your specific project and materials.
4. Store model cement in a cool, dry place away from direct sunlight and heat sources to prevent premature drying or degradation.
5. Practice proper safety precautions when working with model cement, including wearing gloves and eye protection to avoid skin contact or accidental splashes.
In conclusion, model cement is an indispensable tool for hobbyists and model builders alike, offering a reliable and effective way to bond plastic parts together with precision and strength. By choosing the right type of cement, mastering application techniques, and following best practices, you can achieve professional-quality results in your model-making projects. So next time you reach for your modelling supplies, make sure to have a bottle of model cement at the ready – it’s the glue that holds it all together.
