The Essential Guide To Model Cement: Everything You Need To Know

When it comes to building models, whether they be scale models of cars, planes, or buildings, one of the most important tools in a modeler’s arsenal is model cement. Model cement, also known as plastic cement or polystyrene cement, is a type of adhesive specifically designed for bonding plastic models together. In this article, we will explore everything you need to know about model cement, from its different types to how to use it effectively.

Types of model cement

There are several different types of model cement available on the market, each with its own unique properties and uses. The most common types of model cement include:

1. Liquid Cement: Liquid cement is one of the most popular types of model cement. It comes in a small bottle with a brush applicator attached to the cap, making it easy to apply to small and delicate parts. Liquid cement works by softening the plastic surfaces it is applied to, allowing them to bond together when pressed firmly. This type of cement is ideal for fine detail work and for bonding small parts together.

2. Tube Cement: Tube cement, also known as gel cement, comes in a tube-like container and has a thicker consistency than liquid cement. Tube cement is great for bonding larger parts together, as it dries slower than liquid cement, giving you more time to adjust the parts before the bond sets. Tube cement is also less likely to run or drip, making it easier to control and apply.

3. Polystyrene Cement: Polystyrene cement is specifically formulated for bonding polystyrene plastic models. This type of cement works by chemically melting the plastic surfaces it is applied to, creating a strong bond between the parts. Polystyrene cement is great for bonding plastic models made from polystyrene plastic, such as model cars and airplanes.

4. Epoxy Cement: Epoxy cement is a two-part adhesive that forms an incredibly strong bond between plastic parts. Epoxy cement consists of a resin and a hardener that must be mixed together before application. Once mixed, epoxy cement sets very quickly, creating a bond that is resistant to heat, chemicals, and moisture. Epoxy cement is ideal for bonding heavy or load-bearing parts together.

How to Use model cement

Using model cement effectively requires some practice and skill, but with the right techniques, you can achieve strong, clean bonds between plastic parts. Here are some tips for using model cement:

1. Prepare the surfaces: Before applying model cement, make sure the surfaces you are bonding are clean and free of any dirt, grease, or debris. This will ensure a strong bond between the parts.

2. Apply a small amount of cement: Be sparing with the amount of cement you apply to the surfaces. A little goes a long way, and applying too much cement can cause excess to ooze out and create a messy bond.

3. Press the parts together firmly: Once you have applied the cement to the surfaces, press the parts together firmly to create a strong bond. Hold the parts in place for a few seconds to allow the cement to set.

4. Clean up any excess cement: If any excess cement oozes out from the bond line, clean it up quickly with a cotton swab or a clean cloth dampened with cement thinner. This will help create a clean and tidy bond.

In conclusion, model cement is an essential tool for any modeler looking to create strong bonds between plastic parts. By choosing the right type of cement for your project and using it effectively, you can achieve professional-looking results that will stand the test of time. So the next time you embark on a modeling project, make sure you have plenty of model cement on hand to help bring your creations to life.
