Model cement, often referred to simply as plastic cement, is a critical component in model building. Whether you are working on model airplanes, cars, ships, or any other kind of miniature scale model, having the right type of cement is essential for creating a strong bond between parts. In this comprehensive guide, we will delve into everything you need to know about model cement, from its different types to its application techniques.
Types of model cement
There are several types of model cement available in the market, each specifically formulated for different types of plastic materials. The most common types include:
1. Polystyrene cement: This type of cement is designed for use with polystyrene plastic models. It works by softening and partially melting the plastic, creating a strong bond when the parts are pressed together. Polystyrene cement is ideal for plastic model kits such as airplanes and cars.
2. Cyanoacrylate (super glue): Cyanoacrylate, also known as super glue, is a fast-acting adhesive that forms a strong bond between plastic parts. It works by bonding the molecules of the plastic together, creating a durable connection. Super glue is suitable for small-scale models and can also be used for other materials such as metal and wood.
3. Epoxy resin: Epoxy resin is a two-part adhesive that forms a very strong bond between plastic parts. It consists of a resin and a hardener that must be mixed together before application. Epoxy resin is ideal for bonding larger parts or for creating structural joints in models.
Application Techniques
Proper application of model cement is crucial for creating a seamless and strong bond between plastic parts. Here are some tips for effectively using model cement:
1. Clean the surfaces: Before applying the cement, make sure to clean the surfaces of the plastic parts to be bonded. Any dust, oil, or debris on the surfaces can prevent the cement from adhering properly.
2. Apply a small amount: Only a small amount of cement is needed to create a bond between plastic parts. Using too much cement can cause the parts to melt or warp, leading to a weak bond.
3. Press the parts together: After applying the cement, press the plastic parts together firmly to ensure a strong bond. Hold the parts in place for a few seconds to allow the cement to dry and set.
4. Avoid excessive handling: Once the cement has been applied and the parts have been bonded, avoid excessive handling of the model until the cement has fully cured. This will prevent any accidental breakage or weakening of the bond.
Safety Precautions
When working with model cement, it is important to take certain safety precautions to protect yourself and others. Some key safety tips include:
1. Work in a well-ventilated area: Model cement fumes can be toxic if inhaled in large amounts. Make sure to work in a well-ventilated area or use a respirator to avoid breathing in the fumes.
2. Use gloves: Model cement can be harsh on the skin and may cause irritation or allergic reactions. Wear gloves when handling the cement to protect your hands.
3. Keep out of reach of children: Model cement should be stored in a secure location away from children and pets. The cement can be harmful if ingested or inhaled by young children.
In conclusion, model cement is an essential tool for model builders looking to create strong and durable bonds between plastic parts. By understanding the different types of cement available, mastering the application techniques, and following safety precautions, you can effectively incorporate model cement into your model building projects. Whether you are a beginner or an experienced model builder, having the right cement on hand will ensure the success of your creations.
