Plastic cement, also known as plastic welding adhesive, is a type of adhesive specifically designed to be the strongest glue for plastic bonding and joining plastic materials together. It is commonly used in various industries, including model-making, construction, and plumbing.

Model glue for Plastics or plastic cement, is a type of modeling glue, and it comes in a liquid form and is applied to the surfaces to be bonded. The adhesive works by chemically melting the plastic, creating a strong bond as the melted parts fuse together. This process is often referred to as "plastic welding" because it mimics the fusion of plastic that occurs during traditional welding processes.

Model glue for Plastics will be perfect for scale models made of Plasticard or polystyrene or ABS (acrylonitrile butadiene styrene) materials, Styrene, and HIPS, and they offer several advantages, such as:

Strong bond: It creates a durable and reliable bond between surfaces, ensuring they stay securely attached.
Seamless finish: The chemical melting action allows for a seamless connection between parts, eliminating visible seams or gaps.
Compatibility: It is formulated to work specifically with plastics, providing optimal adhesion and minimizing the risk of damaging the material.
Quick drying: It typically dries relatively quickly, allowing for efficient assembly and reducing the need for extended curing times.

It is important to note that plastic cement is a strong solvent and it should be used in a well-ventilated area due to the release of fumes during the bonding process.

Best glue for plastic

The best glue for plastic depends on the specific type of material you are working with and the intended use of the bonded items. Here are some commonly recommended options:

Cyanoacrylate Glue: Commonly known as Instant Glue, is a versatile and widely available option for bonding almost everything. It forms a strong and fast bond, but it can be brittle, so it may not be ideal for applications that require flexibility.
Epoxy Resin: Epoxy is a popular adhesive due to its strong and durable bond. It works well with a variety of materials and provides excellent structural strength. Epoxy resin is a two-part product that requires mixing before application.
Polyurethane Adhesive: It is known for its flexibility and versatility. It can bond with different types of plastics, including those that are difficult to bond with other options. It provides a strong bond and has good resistance to moisture.
Solvent-Based Adhesives - Skullglue: It works by chemically melting the surfaces, creating a strong bond. Solvent-based adhesives, such as acetone or MEK (methyl ethyl ketone), can be effective for bonding certain types of plastics. These adhesives also work by dissolving the surfaces, allowing them to fuse together when the solvent evaporates.

It's important to note that the best glue for plastic can vary depending on the specific material type and the application. It's always a good idea to test on a small, inconspicuous area before applying it to the entire project.
