Model cement, often referred to as plastic cement or polystyrene cement, is an essential tool for anyone interested in building scale models. Whether you’re a seasoned model builder or just starting out, understanding the different types of model cement and how to use them effectively will ensure that your model building projects are successful. In this article, we’ll cover everything you need to know about model cement and its various applications.
**What Is model cement?**
Model cement is a specialized adhesive designed specifically for bonding plastic models together. It is commonly used in the assembly of plastic scale models such as airplanes, cars, ships, and figures. Model cement is formulated to create strong bonds between plastic parts without damaging the surface details or causing warping.
**Types of model cement**
There are several types of model cement available on the market, each with its own unique properties and applications. The most common types of model cement include:
1. **Liquid Cement:** Liquid cement is a thin, watery adhesive that is applied using a brush or dropper. It works by softening the plastic surfaces of the parts being bonded, allowing them to fuse together to form a strong bond.
2. **Tube Cement:** Tube cement is a thicker, gel-like adhesive that is dispensed from a squeeze tube. It is ideal for bonding larger surfaces and provides a more controlled application than liquid cement.
3. **Thin Cement:** Thin cement is a solvent-based adhesive that is used for bonding small parts and delicate details. It has a low viscosity, allowing it to flow into tight spaces and create seamless bonds.
4. **Gap-Filling Cement:** Gap-filling cement is a thicker adhesive designed to fill in gaps and seams between parts. It is commonly used for repairing and reinforcing models that have been damaged or have missing parts.
**How to Use model cement**
Using model cement effectively requires careful preparation and application techniques. Here are some tips for using model cement:
1. **Prepare the Parts:** Before applying model cement, make sure the parts are clean and free of any debris or grease. This will ensure a strong bond between the surfaces.
2. **Apply the Cement:** Depending on the type of model cement you are using, apply a small amount of adhesive to one of the surfaces to be bonded. Press the parts together firmly and hold them in place until the cement sets.
3. **Avoid Excess Cement:** Be mindful of using too much cement, as it can cause unsightly smudges and excess material to ooze out from the seams. Use a small amount of cement and apply it sparingly for best results.
4. **Allow for Drying Time:** Model cement typically dries within a few hours, but it’s best to allow the bond to fully cure overnight before handling the model. This will ensure a strong and durable connection between the parts.
**Benefits of Using Model Cement**
Model cement offers several advantages over traditional adhesives such as super glue or epoxy. Some of the benefits of using model cement include:
1. **Strong Bonds:** Model cement creates strong and durable bonds between plastic parts, ensuring that they stay securely in place over time.
2. **Seamless Finishes:** Model cement dries clear and leaves no visible residue, creating seamless connections between parts for a professional-looking finish.
3. **Precision Application:** Model cement allows for precise control over the adhesive application, making it easy to bond small and delicate details without causing damage.
4. **Compatible with Polystyrene:** Model cement is specially formulated to bond polystyrene plastic, making it the ideal choice for plastic scale models made from this material.
In conclusion, model cement is an essential tool for model builders looking to create high-quality scale models. By understanding the different types of model cement and how to use them effectively, you can achieve professional results and bring your models to life. So next time you embark on a new model building project, be sure to have model cement on hand to ensure a successful build.
