Product Design - Adhesives 0.0 / 5 ? Design Technology: Product DesignAdhesivesASAQA Created by: AliceCreated on: 01-04-15 22:22 5246713 Across 1. Solvent, ideal for joining thermoplastics or other materials, bonds produced are very strong, non porous & resistant to weathering, ideal for outdoor signs, permanent, thermoplastics only, (7, 6) 5. Used for joining lightweight materials, stored in a pressurised can with a chemical expellant, even surface can be applied, easy to apply, accurate, not permanent (5, 4) Down 2. Desired image is cut out & self adheres to a variety of surfaces on a temporary basis, comes in range of colours, easy to apply, can have printable surface, not permanent, relatively weak, can be removed accidentally (8, 7, 4) 3. Thermosetting plastic, when the polymer & catalyst are mixed they heat & harden, extremely strong, resistant to heat, cannot easily be removed when set (5, 5) 4. Inexpensive, non toxic, temporary joining method, used in packaging industry & transparent containers on beauty products (8, 4) 6. Synthetic polymer, vinyl acetate is suspended in an emulsion of water making it good for porous materials (wood/paper), permanent, strong, hardwearing, inexpensive, not permanent (3) 7. Softens when heated, viscosity increases & becomes molten, solidifies when cools, quick to apply, joins variety of materials, can cause burns, only used for lightweight materials (3, 4, 4)
