Model cement, often referred to as plastic cement or polystyrene cement, is an essential tool for anyone involved in scale model building. Whether you are a seasoned hobbyist or just starting out, understanding the ins and outs of model cement is crucial for achieving optimal results in your projects. In this article, we will delve into what model cement is, how it works, its various types, and some tips for using it effectively.
What is model cement?
Model cement is a type of adhesive specifically designed for bonding plastic components in scale model kits. It has a chemical composition that allows it to soften and partially dissolve the plastic materials it comes into contact with, creating a strong bond when the parts are pressed together. This characteristic makes model cement more effective than standard glue for attaching plastic pieces that need to be securely joined.
How Does model cement Work?
Model cement works through a process called solvent welding. When applied to the surfaces of two plastic pieces, the cement softens the plastic and creates a bond that is as strong as the original material itself. The solvent in the cement evaporates, leaving behind a joint that is seamless and durable. This method of assembly is especially useful for models that require precise alignment and tight fits, as the cement can fill in small gaps and imperfections.
Types of model cement
There are several types of model cement available on the market, each with its own set of properties and applications. The most common types include:
1. Liquid Cement: This type of cement comes in a bottle with a brush applicator, making it easy to apply to small areas. Liquid cement is ideal for joining small parts and creating fine details in scale models.
2. Tube Cement: Tube cement is thicker in consistency than liquid cement and is typically dispensed through a nozzle. It is more suitable for larger pieces and areas that require a stronger bond.
3. Cement Pen: A cement pen is a convenient tool for applying small amounts of cement precisely. It is often used for touch-ups and repairs on completed models.
4. Thin Cement: Thin cement has a lower viscosity than standard cement, allowing it to flow into tight spaces and crevices. It is ideal for bonding small, delicate parts that require a minimal amount of cement.
Tips for Using Model Cement Effectively
To achieve the best results with model cement, consider the following tips:
1. Work in a well-ventilated area: Model cement releases fumes that can be harmful if inhaled. Make sure to work in a well-ventilated space or use a respirator mask to protect yourself.
2. Use sparingly: A little bit of model cement goes a long way. Apply a thin layer of cement to the joining surfaces to avoid excess dripping and mess.
3. Hold parts in place: While the cement sets, hold the parts together firmly to ensure a tight bond. You can also use clamps or rubber bands to keep the pieces in place while the cement dries.
4. Clean excess cement: Use a cotton swab dipped in cement thinner to clean up any excess or spilled cement. This will help prevent unsightly marks on your model.
In conclusion, model cement is an indispensable tool for model builders looking to create professional-looking scale models with precision and durability. By understanding how model cement works, choosing the right type for your project, and following best practices for application, you can take your modeling skills to the next level. So, grab your trusty bottle of model cement, unleash your creativity, and start building your next masterpiece.
