Model cement, also known as plastic cement or polystyrene cement, is an essential tool in the world of scale modeling. Whether you are building model airplanes, cars, ships, or buildings, model cement is a crucial adhesive that ensures the pieces stay together and create a durable and realistic finished product. In this guide, we will explore everything you need to know about model cement, including its uses, types, application techniques, and safety precautions.
Uses of model cement
Model cement is primarily used to bond plastic parts together in scale modeling projects. It works by partially dissolving the plastic surfaces of the parts being joined, creating a strong bond that fuses the pieces together. This bonding process is crucial in creating a seamless and realistic finish on your models, as it eliminates visible seams between parts and helps to strengthen the overall structure of the model.
Model cement can be used on a wide range of plastic materials commonly found in model kits, including polystyrene, ABS, and styrene-butadiene-styrene (SBS) plastics. It is an ideal adhesive for assembling model kits of all scales and complexities, from simple snap-together kits to intricate and detailed models that require precise assembly.
Types of model cement
There are several types of model cement available on the market, each formulated for specific applications and preferences. The most common types of model cement include liquid cement, tube cement, and gel cement.
Liquid cement is the most versatile and widely used type of model cement. It comes in a small bottle with a brush applicator, allowing for precise application and control. Liquid cement is ideal for bonding small parts and creating tight seams between surfaces. It dries quickly and forms a strong bond, making it suitable for most scale modeling projects.
Tube cement, also known as solvent cement, is a thicker adhesive that comes in a tube or squeeze bottle. It is commonly used for bonding larger parts and filling gaps between surfaces. Tube cement has a longer drying time compared to liquid cement, allowing for adjustments to be made before the bond sets completely.
Gel cement is a thicker and more viscous version of liquid cement. It is ideal for vertical surfaces and overhead applications, as it does not run or drip like liquid cement. Gel cement is often preferred for delicate or intricate models that require precision bonding in hard-to-reach areas.
Application Techniques
When using model cement, it is important to follow proper application techniques to ensure a strong and reliable bond between parts. Here are some tips for applying model cement effectively:
1. Prepare the surfaces: Before applying model cement, make sure to clean and dry the surfaces of the parts being joined. This will remove any dirt, grease, or mold release agents that could inhibit bonding.
2. Apply a small amount of cement: Use a brush or applicator to apply a small amount of model cement to one of the surfaces. Avoid applying too much adhesive, as this can cause excess glue to spill out and create unsightly marks on the model.
3. Press the parts together: Carefully align the parts and press them together firmly to ensure a secure bond. Hold the parts in place for a few seconds to allow the cement to begin bonding the surfaces together.
4. Allow time to dry: Let the model cement dry completely before handling or moving the parts. This can take anywhere from a few minutes to several hours, depending on the type of cement used and the size of the parts being bonded.
Safety Precautions
While model cement is a valuable tool in scale modeling, it is important to take precautions when handling and using this adhesive. Model cement contains volatile organic compounds (VOCs) that can be harmful if inhaled or absorbed through the skin. To ensure your safety and protect your health, follow these safety precautions when working with model cement:
1. Work in a well-ventilated area: Always use model cement in a well-ventilated room or workspace. Open windows or use a fan to improve air circulation and reduce exposure to VOCs.
2. Wear protective gear: When handling model cement, wear gloves to protect your skin and a mask to prevent inhalation of fumes. Additionally, avoid contact with eyes and mouth, and wash hands thoroughly after using the adhesive.
3. Store properly: Store model cement in a cool, dry place away from heat sources and direct sunlight. Keep the cap tightly closed when not in use to prevent evaporation and maintain the quality of the adhesive.
4. Dispose of properly: Dispose of empty model cement bottles and used applicators in accordance with local regulations. Do not pour excess cement down the drain or throw it in the trash, as this can be harmful to the environment.
In conclusion, model cement is an indispensable tool for scale modelers seeking to create realistic and detailed models. By understanding its uses, types, application techniques, and safety precautions, you can make the most of this versatile adhesive and achieve professional results in your modeling projects. Remember to choose the right type of model cement for your specific needs, follow proper application techniques, and prioritize safety when working with this adhesive. With the right knowledge and precautions in place, you can enjoy the benefits of model cement and bring your scale models to life with precision and craftsmanship.
