Model cement, also known as plastic cement, is a vital tool for anyone who enjoys building scale models. Whether you are creating model airplanes, tanks, cars, or ships, model cement is essential for securing parts together and creating a strong bond. In this article, we will discuss everything you need to know about model cement and how to use it effectively.
What is model cement?
Model cement is a type of adhesive specifically designed for bonding plastic models together. It is typically a liquid that dries to form a strong bond between plastic parts. Model cement works by softening the surfaces of the plastic parts being bonded, allowing them to fuse together as the solvent evaporates.
There are several different types of model cement available, including liquid cement, tube cement, and gel cement. Each type has its own unique properties and is suitable for different applications. Liquid cement is the most common type and is typically used for general plastic model assembly. Tube cement is thicker and often used for more precise applications, while gel cement is ideal for vertical surfaces and filling gaps between parts.
How to Use model cement
Using model cement is a straightforward process, but there are a few key tips to keep in mind to ensure a strong bond and professional finish. Here are the steps to follow when using model cement:
1. Prepare the parts: Before applying model cement, make sure the surfaces of the plastic parts are clean and free of any dirt, grease, or debris. This will help the cement form a strong bond and prevent any imperfections in the finish.
2. Apply the cement: Using a small brush or applicator, apply a thin layer of model cement to the surfaces of the parts that need to be bonded together. Be careful not to use too much cement, as this can cause the parts to bond incorrectly or create unsightly marks.
3. Press the parts together: Once the cement has been applied, gently press the parts together and hold them in place for a few seconds to allow the bond to form. Avoid moving the parts around too much during this time, as this can weaken the bond.
4. Allow the cement to dry: Model cement typically dries within a few minutes, but it is best to leave the parts undisturbed for at least an hour to ensure the bond is fully cured. Once the cement has dried, any excess can be cleaned up with a cotton swab or hobby knife.
Tips for Using model cement
– Work in a well-ventilated area when using model cement, as the fumes can be harmful if inhaled in large quantities.
– Use a small brush or applicator to apply the cement, as this will help ensure a controlled and even application.
– Store model cement in a cool, dry place to prevent it from evaporating or drying out.
– Practice using model cement on scrap plastic before working on your actual model to get a feel for how it behaves and how much to use.
In conclusion, model cement is an essential tool for anyone who enjoys building scale models. By following the tips and techniques outlined in this article, you can create strong bonds between plastic parts and achieve professional results in your model building projects. Whether you are a beginner or an experienced modeler, model cement is a must-have in your toolkit.
