Various Kinds Of Adhesives And Their Uses
Adhesives, Loctite, paste or glue are materials that are used for sticking. Adhesives play key roles in everyday life. It is like it is going to be tough running our daily activities if these adhesives are missing.
There is a wide range of varieties of adhesives that are available on the market. You should not find it hard locating these precious items for your use. What you always need to remember, though, is that all adhesives are designed for use with different services. What is more, different adhesives have different strengths.
And of all the adhesives, synthetic resin glues are considered the strongest. And long-standing. They harden so well and smoothly. They can be used on different hard surfaces, including metals. Synthetic glue can also fix both porous and non-porous materials. They also become hardened and would not shrink at any one time. If you need them for your sticking; you can always find them in tubes.
Then there are also the polyester resins. They are almost like the epoxies but will not shrink easily. When they hardened, they are ideal for glass fibre.
Silicones are also commonly used adhesives. Silicones can withstand high temperatures. They are resistant to water and are frequently used in electric cabling.
There are also adhesives that are derived from parts of animals. Common ones are the glue cakes that are made from the hides and bones. Then there is the famous gelatin, an adhesive that is even used for cooking. Animal adhesive are used on fabrics, cards and even papers.
Then there are aerosols adhesives as well. They are available in low or moderate viscosity. They are designed to be applied or sprayed on the surface quickly so that the droplets land on the required surface before they dry up. Most of these aerosols adhesives are discharged using a spray gun or an aerosol can.
Designers often use these aerosol adhesives to cause an instant bond on the surface which they can reposition before they are set. One great advantage with the aerosol adhesive is that they are clear, stain-free and are very fine mist when they are sprayed. Even such a delicate paper can be sprayed, and it will not tear. One major disadvantage is that you need to spray in a ventilated area as the substance is highly flammable. You also need to be careful not to inhale the fumes – they can cause issues in your respiratory system.
The polyester resins are utilized in glass, plastics, and metals. Cellulose adhesives can be used in polystyrene, plastics, card, and paper. Urethanes can be used to stick metals, rubber, leather, wood, and plastics. Lastly, the epoxy resins can be used to repair metals, stones, glasses, plastics as well as wood. Vegetable glues will glue papers and cards.
