Model cement, also known as plastic cement or polystyrene cement, is a crucial tool for any hobbyist or model maker. It is a type of adhesive specifically designed for bonding plastic components together, making it an essential item for assembling model kits such as airplanes, cars, ships, and scale models. In this comprehensive guide, we will explore everything you need to know about model cement, its types, uses, application tips, and safety precautions.
Types of model cement
There are two main types of model cement: liquid cement and gel cement. Liquid cement, often sold in small bottles with an applicator brush, is a thin, watery adhesive that works by softening the plastic parts it comes into contact with, allowing them to fuse together when pressure is applied. On the other hand, gel cement is a thicker, more viscous adhesive that is better suited for vertical surfaces and gap filling.
Uses of model cement
Model cement is primarily used for assembling plastic model kits. Whether you are building a miniature plane, car, ship, or any other plastic model, model cement is essential for joining the various parts together. It creates strong, permanent bonds that ensure your finished model is sturdy and well-built. Additionally, model cement can be used to repair broken or damaged plastic models by reattaching pieces that have come loose.
Application Tips
To achieve the best results with model cement, it is important to follow these application tips:
1. Clean the surfaces: Before applying model cement, make sure to clean the surfaces of the plastic parts to be bonded. Any dirt, grease, or mold release agents can prevent the cement from adhering properly.
2. Apply a small amount: Less is more when it comes to model cement. Only apply a thin layer to one of the surfaces to be bonded. Excessive use of cement can cause the parts to melt or warp.
3. Hold the parts together: After applying the cement, press the two parts together firmly and hold them in place for a few seconds. This will ensure a strong bond between the components.
4. Allow time to dry: Model cement typically dries within a few minutes to a few hours, depending on the type and brand. Be patient and avoid touching or moving the parts until the cement has fully cured.
5. Use in a well-ventilated area: Model cement can emit fumes that may be harmful if inhaled. Always work in a well-ventilated area or use a respirator mask to protect yourself.
Safety Precautions
While model cement is a valuable tool for model making, it is important to take proper safety precautions when using it. Here are some safety tips to keep in mind:
1. Work in a well-ventilated area: As mentioned earlier, model cement can release fumes that may be harmful if inhaled. Make sure to work in a well-ventilated area or use a fume extractor to remove any noxious vapors.
2. Avoid contact with skin and eyes: Model cement is a strong adhesive that can cause irritation or burns if it comes into contact with skin or eyes. Wear gloves and safety glasses when handling the cement to protect yourself.
3. Store properly: When not in use, store model cement in a cool, dry place away from direct sunlight and heat sources. This will help prevent the cement from deteriorating or drying out prematurely.
4. Keep out of reach of children and pets: Model cement contains toxic chemicals that can be harmful if ingested. Store it out of reach of children and pets to prevent accidents.
In conclusion, model cement is an indispensable tool for any hobbyist or model maker looking to create high-quality plastic models. By choosing the right type of cement, following application tips, and taking safety precautions, you can achieve professional-looking results while ensuring your safety. So, whether you are a seasoned model maker or a beginner, don’t forget to stock up on model cement for your next project.
