Different types of plastic adhesives are used for bonding various materials in creative, assembly, maintenance, and repair applications. They have high bond strength, good insulating properties, and excellent resistance to impact, heat, and chemicals. Epoxy is the strongest adhesive, while hot-melt adhesive is used for assembling electrical and automobile parts. Cyanoacrylate is known as super glue and is effective in repairing skin and bones. However, plastic adhesives can emit strong fumes, so it’s important to use them in a well-ventilated area and wear protective gear.
Different types of plastic adhesives such as epoxies, resins, acrylics, silicones and hot-melt adhesives are regularly used to bond plastics, metals, glass and a host of other purposes. They are used to address creative, assembly, maintenance and repair problems in craft, construction, manufacturing and engineering applications. Such use of plastic adhesive is known to have high bond strength, good insulating properties, and excellent impact, heat, and chemical resistance. Plastic adhesive products can be purchased in ready-to-use packs, containers, glue gun cartridges and syringes.
Because a plastic adhesive can be quite strong, it’s important to read and understand the instructions on the labels before using. Some types of plastic
adhesives are available in solid, semi-solid, viscous or liquid form. Some adhesives are water-based, while others require careful handling as they must be mixed with organic solvents.
Epoxy adhesives, perhaps the strongest of all adhesives, are used to build aircraft, vehicles and sporting equipment. It is a solvent free, waterproof adhesive which, in addition to its strength, has the added benefit of being very durable and resistant to heat and chemicals. It can be cured by heat treatment and does not shrink much in the process. Epoxy comes in two parts, a resin and a hardener, and these must be mixed before use.
Hot-melt adhesive is a solid adhesive based on thermoplastic resins. It comes in solid or semi-solid form and does not need to be mixed with an organic solvent. It is first melted by heating, then applied in a layer where required, and then adheres to that surface as it cools and hardens. Hot melt adhesive is used to assemble electrical parts, automobile parts and packing cartons.
Cyanoacrylate, better known as super glue, is a water-resistant plastic adhesive that is known to bond well with metals, among other things; however, it doesn’t work well with smooth glass. Super glue can be used to glue a wide variety of items such as electronics, model making, corals and ballerina shoes. It has been found effective in repairing skin and bones and closing wounds in both humans and animals.
While plastic adhesive products can be very useful, they can have some health-related drawbacks. They may give off strong fumes which cause eye and skin irritation. Applying the plastic adhesive is a well-ventilated area, and wearing a protective skin cover can definitely come in handy.
