Green Stuff World Cement Glue for Plastics 40ml - Plastic Weld Adhesive - Hobby Heaven 🔗 GREEN STUFF WORLD PLASTIC CEMENT 🔗 40ml Liquid Plastic Weld Brush Applicator | Chemical Welding | Invisible Seams 🧪 Chemical Welding vs Gluing This isn't glue in the traditional sense – it's a solvent-based cement that works by melting the plastic surfaces and fusing them together. When you apply plastic cement to polystyrene (the material most model kits are made from), it dissolves the surface layer slightly. Press the parts together and the molten plastic intermingles, then re-solidifies as one piece. You're essentially welding plastic at room temperature. This means the bond is part of the plastic itself, not a layer of adhesive stuck between two surfaces.
