Model cement, commonly known as plastic cement or polystyrene cement, is an essential tool for any model maker. Whether you are building intricate scale models of planes, cars, or ships, or simply putting together a small plastic model kit, model cement is crucial for achieving a strong, long-lasting bond between plastic parts.
What is model cement?
Model cement is a type of adhesive specifically designed for bonding plastic components together. Unlike ordinary glue, which dries clear and is not ideal for plastic surfaces, model cement creates a chemical reaction that melts the plastic parts slightly, allowing them to fuse together. This results in a much stronger and more durable bond than what standard glue can offer.
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 include:
1. Liquid Cement: This is the most widely used type of model cement. It comes in a small bottle with a brush applicator, making it easy to apply to small parts and hard-to-reach areas. Liquid cement works by capillary action, seeping into the gaps between plastic parts and creating a strong bond once dried.
2. Tube Cement: Tube cement is similar to liquid cement but comes in a tube form with a nozzle for precise application. It is ideal for larger plastic parts or for filling in larger gaps between components.
3. Cement Pen: Cement pens are a convenient alternative to bottled cement. They are perfect for applying small amounts of cement to specific areas without making a mess.
4. Gel Cement: Gel cement has a thicker consistency than liquid cement, making it ideal for vertical surfaces or for bonding large plastic parts. It also has a longer drying time, allowing for adjustments to be made before the bond sets completely.
Benefits of model cement
Model cement offers several key benefits that make it an essential tool for model makers:
1. Strong Bond: Model cement creates a chemical bond between plastic parts, resulting in a strong, durable bond that can withstand the test of time.
2. Invisible Seam: When applied correctly, model cement melts the plastic parts slightly, allowing them to fuse together seamlessly. This results in an invisible seam between the parts, giving your model a professional finish.
3. Quick Drying: Most model cements dry within minutes, allowing you to work efficiently and move on to the next step of your model-making project.
Tips for Using Model Cement
To get the best results with model cement, follow these tips:
1. Prepare the Surfaces: Before applying model cement, make sure the plastic surfaces are clean and free of any debris or oils. This will ensure a strong bond between the parts.
2. Apply the Cement Sparingly: A little goes a long way with model cement. Apply a thin layer of cement to one of the plastic parts and press the parts together firmly to create a bond.
3. Use in a Well-Ventilated Area: Model cement contains strong fumes that can be harmful if inhaled. Make sure to use it in a well-ventilated area or wear a mask to protect yourself.
4. Practice Patience: While model cement dries relatively quickly, it is important to give it enough time to cure completely before handling the model. This will ensure a strong and long-lasting bond.
In conclusion, model cement is a versatile and essential tool for model makers of all skill levels. With its ability to create strong bonds between plastic parts and its ease of use, model cement is a must-have for anyone looking to take their model-making skills to the next level. Whether you are building a complex scale model or simply putting together a small kit, model cement will help you achieve professional results every time.
