Model cement, also known as plastic cement or plastic model glue, is a type of adhesive used in the construction of scale model kits. Whether you’re building model cars, airplanes, ships, or trains, having the right type of model cement is essential for creating strong and durable bond between plastic parts.
There are various types of model cement available on the market, each with its own unique properties and uses. In this article, we will explore the different types of model cement, how to choose the right one for your project, and provide tips on how to use model cement effectively.
Types of model cement
1. Liquid Cement: Liquid model cement comes in a bottle with a brush applicator attached to the cap. This type of cement is easy to apply and provides a quick bond between plastic parts. Liquid cement works by melting the plastic surfaces and fusing them together once dried.
2. Tube Cement: Tube cement is a thicker version of liquid cement and comes in a tube with a fine applicator tip. This type of cement is ideal for precise applications and filling gaps between plastic parts. Tube cement dries slower than liquid cement, giving you more time to adjust the parts before the bond sets.
3. Plastic Welding Cement: Plastic welding cement is a specialized type of model cement that chemically bonds plastic parts together, creating a strong and permanent bond. This type of cement is ideal for joining dissimilar plastics and creating seamless joints.
4. Cement Pens: Cement pens are a convenient and mess-free way to apply model cement to small areas. The pen-like applicator allows for precise application of cement without the need for brushes or tubes.
Choosing the Right model cement
When choosing model cement for your project, consider the following factors:
1. Type of Plastic: Different types of plastic require specific types of cement. For example, polystyrene plastic is best bonded with liquid cement, while ABS plastic requires plastic welding cement for a strong bond. Make sure to read the labels on the cement bottles to ensure compatibility with the plastic parts you are working with.
2. Application: Consider the size and complexity of your model kit when choosing model cement. Liquid cement is ideal for large surface areas, while tube cement is better suited for small and detailed parts. Plastic welding cement is best for creating seamless joints and strong bonds.
3. Drying Time: Depending on the type of model cement you choose, the drying time can vary. Liquid cement dries quickly, while tube cement and plastic welding cement may require more time to set. Consider the working time you need before the bond sets to ensure a successful assembly.
Tips for Using model cement
1. Clean Surfaces: Before applying model cement, make sure to clean the plastic parts with soap and water to remove any dirt, grease, or residue. This will ensure a strong bond between the parts.
2. Test Fit: Dry-fit the plastic parts together before applying cement to ensure a proper alignment. Once you are satisfied with the fit, apply a thin layer of cement to the joining surfaces and press the parts together firmly.
3. Use in a Well-Ventilated Area: Model cement contains strong fumes that can be harmful if inhaled. Make sure to use model cement in a well-ventilated area or wear a mask to protect yourself from the fumes.
4. Clean Up: Clean any excess model cement with a cotton swab dipped in acetone or nail polish remover. Be careful not to spill acetone on painted surfaces, as it can damage the finish.
In conclusion, model cement is an essential tool for model builders looking to create strong and durable bonds between plastic parts. By choosing the right type of model cement for your project and following these tips for effective use, you can achieve professional-looking results in your scale model constructions. So go ahead, grab your model cement and get ready to bring your models to life!
