When it comes to assembling scale models, one essential tool that every hobbyist needs is model cement. Also known as polystyrene cement or plastic cement, this adhesive is specifically designed for bonding plastic parts of scale models together. Whether you are building model cars, airplanes, ships, or buildings, model cement is a must-have for creating professional and sturdy assemblies.
model cement is a specialized adhesive that is formulated to create strong bonds between plastic parts without damaging or melting the material. It works by softening and partially melting the plastic surfaces it comes into contact with, allowing them to fuse together as the cement dries. This results in a seamless bond that is both strong and durable, making it ideal for holding together intricate parts of scale models.
There are several different types of model cement available on the market, each with its unique properties and uses. The most common types include liquid cement, gel cement, and cement with a brush applicator. Liquid cement is the most versatile option and is suitable for general assembly work. Gel cement is thicker and more viscous, making it ideal for filling gaps and creating stronger bonds. Cement with a brush applicator is convenient for applying precise amounts of adhesive to small parts.
When choosing a model cement, it is essential to consider the material of the plastic parts you will be bonding. While most model cements are designed to work with polystyrene plastic, some formulations may be more suitable for specific types of plastic. It is always best to test the cement on a scrap piece of plastic before using it on your model to ensure compatibility and avoid any potential damage.
Using model cement is a straightforward process, but there are a few tips and tricks to keep in mind to achieve the best results. Before applying the cement, it is essential to ensure that the surfaces to be bonded are clean and free of any debris or grease. This can be done by lightly sanding the surfaces or using a plastic-friendly cleaning solvent. Additionally, it is helpful to dry fit the parts together first to ensure a proper fit before applying the adhesive.
To apply the model cement, simply place a small amount on one of the surfaces to be bonded and press the parts together firmly. The cement will begin to soften the plastic, allowing them to fuse together as it dries. It is important to hold the parts in place for a few moments to ensure a strong bond. Excess cement can be wiped away with a cotton swab or a damp cloth before it dries.
After bonding the parts together, it is crucial to allow the cement to fully cure before handling the assembly. This typically takes a few hours, depending on the type of cement used and the ambient temperature. It is best to let the model sit undisturbed during this time to prevent any accidental breakage or weakening of the bond.
While model cement is an excellent tool for creating precise and secure assemblies, it is essential to use it in a well-ventilated area and follow all safety precautions. The fumes from the cement can be harmful if inhaled in large quantities, so it is best to work in a well-ventilated area or wear a mask. Additionally, it is essential to keep the cement away from children and pets to prevent accidental ingestion or contact with skin.
In conclusion, model cement is a vital tool for any scale model enthusiast looking to create professional-looking assemblies. With its ability to create strong and durable bonds between plastic parts, model cement is a versatile adhesive that can be used for a wide range of modeling projects. By following the tips and tricks outlined in this guide, you can confidently use model cement to bring your scale models to life with precision and accuracy.
