Model cement, also known as plastic cement or polystyrene cement, is an essential tool for anyone who enjoys building plastic models. Whether you are building model airplanes, cars, ships, or any other type of plastic model, model cement is a crucial component in ensuring a strong and lasting bond between plastic parts. In this guide, we will take an in-depth look at model cement, its uses, application techniques, safety precautions, and much more.
What is model cement?
Model cement is a type of adhesive specifically designed for bonding plastic parts together. It is commonly used in the assembly of plastic model kits, such as scale models of vehicles, aircraft, ships, and figures. Model cement works by dissolving a thin layer of plastic on the surface of the parts being joined, creating a strong chemical bond as it dries.
Types of model cement
There are several different types of model cement available on the market, each with its own unique properties and applications. The most common types include:
1. Liquid Cement: Liquid cement comes in a small bottle with a brush applicator for easy and precise application. It is great for bonding small plastic parts together quickly and easily.
2. Tube Cement: Tube cement is a thicker consistency than liquid cement and is ideal for bonding larger plastic parts that require a stronger bond. It is typically squeezed out of a tube and applied with a separate brush or applicator.
3. Gel Cement: Gel cement has a thicker consistency than both liquid and tube cement, making it perfect for vertical applications or bonding parts with gaps. It provides a strong and durable bond when used correctly.
How to Use model cement
Using model cement is a straightforward process, but it requires precision and care to ensure a strong bond between plastic parts. Here are some steps to follow when using model cement:
1. Prepare your work area by laying down a protective surface, such as a plastic sheet or newspaper, to prevent any spills or accidents.
2. Ensure that the parts you are bonding are clean and free of any dirt, grease, or debris. This will help the model cement adhere to the plastic surfaces more effectively.
3. Apply a small amount of model cement to one of the surfaces you wish to bond. Use a brush or applicator to spread the cement evenly over the surface.
4. Press the two parts together firmly, making sure to align them correctly. Hold them in place for a few seconds to allow the cement to begin bonding the plastic surfaces.
5. Allow the model cement to dry fully before handling the bonded parts. This usually takes anywhere from a few minutes to several hours, depending on the type of cement used and the size of the parts being bonded.
Safety Precautions
While model cement is a relatively safe adhesive to use, it is essential to take some safety precautions to protect yourself and others from potential harm. Here are some safety tips to keep in mind when working with model cement:
1. Always work in a well-ventilated area to prevent inhaling fumes from the cement, which can be harmful to your health.
2. Wear gloves to protect your skin from coming into direct contact with the model cement, as it can cause irritation or allergic reactions in some individuals.
3. Keep the model cement away from children and pets, as it is toxic if ingested and can cause serious harm.
4. Store the model cement in a cool, dry place away from heat sources or open flames to prevent accidents or spills.
In conclusion, model cement is a valuable tool for anyone who enjoys building plastic models. By understanding the different types of cement available, how to use it correctly, and taking appropriate safety precautions, you can create professional-looking models that will stand the test of time. Whether you are a beginner or an experienced model builder, model cement is an essential component in your modeling arsenal.
