Model cement, also known as plastic cement or polystyrene cement, is a must-have tool for any model builder or hobbyist. Whether you’re assembling scale models, miniature figurines, or other plastic materials, model cement is essential for creating durable and long-lasting bonds. In this comprehensive guide, we’ll take a closer look at what model cement is, how it works, and some helpful tips for using it effectively.
What is model cement?
Model cement is a specially formulated adhesive designed for bonding plastic materials together. Unlike traditional super glue or epoxy, model cement is specifically formulated to bond plastic surfaces by actually melting the plastic and fusing the pieces together. This results in a strong and durable bond that is ideal for plastic model assembly.
How Does model cement Work?
Model cement typically comes in liquid form and is applied using a brush or needle-tip applicator. When applied to the surfaces to be bonded, the cement softens the plastic by dissolving the top layer of the material. This allows the plastic to fuse together as the cement evaporates, creating a strong and seamless bond.
It’s important to note that model cement is designed specifically for use with plastic materials such as polystyrene. It will not work on other materials like metal or wood, so it’s essential to use the right adhesive for the job.
Tips for Using model cement
1. Prepare Your Surfaces: Before applying model cement, make sure to clean and prepare the surfaces to be bonded. Remove any dust, grease, or debris that could interfere with the bonding process.
2. Use in a Well-Ventilated Area: Model cement can emit fumes that may be toxic if inhaled in large quantities. Always use model cement in a well-ventilated area to avoid breathing in harmful vapors.
3. Work Quickly: Model cement dries fast, so it’s essential to work quickly once you’ve applied the adhesive to your surfaces. Make sure to align the pieces properly before the cement sets to ensure a strong bond.
4. Be Precise: Model cement is a powerful adhesive, so it’s crucial to be precise when applying it to your surfaces. Use a small brush or needle-tip applicator to control the amount of cement applied and avoid excess glue.
5. Let It Cure: After bonding your plastic pieces together with model cement, allow sufficient time for the adhesive to cure completely. This will ensure a strong and durable bond that will stand the test of time.
Different Types of Model Cement
There are several different types of model cement available on the market, each with its own unique properties and applications. Here are some of the most common types of model cement:
1. Liquid Cement: Liquid model cement is the most popular and versatile type of adhesive for plastic models. It comes in a bottle with a brush or needle-tip applicator for easy application.
2. Tube Cement: Tube model cement is a thicker, gel-like adhesive that is ideal for bonding larger plastic pieces together. It typically comes in a tube with a nozzle for precise application.
3. Cement Pen: Cement pens are a convenient alternative to traditional model cement bottles. They feature a fine-tip applicator that allows for precise application of the adhesive.
In conclusion, model cement is an essential tool for any model builder or hobbyist working with plastic materials. By following these tips and guidelines, you can create strong and durable bonds that will last for years to come. Whether you’re assembling scale models, miniature figurines, or other plastic projects, model cement is sure to become your go-to adhesive for all your modeling needs.
