Model cement, commonly referred to as plastic cement, is an essential tool for any hobbyist or model maker. Whether you are building model airplanes, cars, ships, or any other type of plastic model, model cement is crucial for creating strong and durable bonds between plastic parts. 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 used to bond plastic parts together to create a solid and permanent connection. This adhesive is specifically designed for plastic models because it works by melting the plastic surfaces and fusing them together as it dries. Unlike other types of adhesives like super glue or epoxy, model cement is formulated to bond plastic parts seamlessly without leaving any visible marks or residue.
Model cement is commonly used in building scale models of airplanes, cars, ships, and other plastic models. It is also used for repairing broken plastic parts or adding small details to models. Additionally, model cement can be used to scratch build custom models or dioramas by combining different plastic parts together.
Types of model cement
There are several types of model cement available on the market, each with its own unique characteristics and intended uses. The most common types of model cement include liquid cement, tube cement, and cement pens.
Liquid cement is a thin adhesive that is applied with a brush or applicator tip. It is ideal for bonding small plastic parts and creating seamless joints between pieces. Liquid cement works by capillary action, allowing it to flow into tight spaces and create strong bonds.
Tube cement is a thicker adhesive that is squeezed out of a tube and applied directly to the plastic surfaces. It is ideal for bonding larger pieces together or for filling gaps between parts. Tube cement dries quickly and creates a strong bond, making it perfect for structural components of a model.
Cement pens are a convenient and mess-free option for applying adhesive to plastic models. These pens have a fine applicator tip that allows for precise application of cement to small details or tight spaces. Cement pens are perfect for adding small parts or accessories to a model with ease.
Application Techniques
When using model cement, it is important to follow proper application techniques to ensure a strong and clean bond between plastic parts. Here are some tips for applying model cement effectively:
1. Clean the plastic surfaces: Before applying model cement, make sure to clean the plastic parts with soap and water to remove any dirt, dust, or oils that may interfere with the bond.
2. Apply a small amount of cement: Use a brush, applicator tip, or cement pen to apply a small amount of cement to the surfaces you wish to bond. Avoid using too much cement, as this can cause excess to ooze out and create messy joints.
3. Press the parts together: Once the cement is applied, press the plastic parts together firmly to create a strong bond. Hold the parts in place for a few seconds to allow the cement to dry and set.
4. Clean up excess cement: Use a cotton swab or toothpick dipped in cement thinner to clean up any excess adhesive that may have seeped out from the joints. This will help create a clean and seamless finish to your model.
Safety Precautions
While model cement is a safe and effective adhesive for plastic models, it is important to take proper safety precautions when using this product. Here are some safety tips to keep in mind:
1. Work in a well-ventilated area: Model cement can emit fumes that may be harmful if inhaled. Always work in a well-ventilated area or use a fume extractor to remove any vapors from the air.
2. Use gloves and eye protection: When handling model cement, wear gloves to protect your skin from irritation or contact with the adhesive. Additionally, wear safety goggles to protect your eyes from accidental splashes or spills.
3. Keep out of reach of children: Model cement should be stored in a safe place away from children and pets, as it can be harmful if ingested or inhaled.
In conclusion, model cement is an essential tool for any model maker looking to create professional and durable plastic models. By understanding the uses, types, application techniques, and safety precautions of model cement, you can confidently build and customize your own plastic models with ease. Next time you embark on a model making project, remember to reach for your trusty bottle of model cement to bring your creations to life.
