Types Of Adhesives And Their Application
Adhesives, Loctite, paste or glue are materials that are used for sticking. Adhesives are instrumental in our everyday life. It is almost as if our daily activities will be paralyzed if these adhesives are not available.
There are many varieties of adhesives that are available on the market. It should not be difficult for anyone to locate these precious items for their use. What you should need to remember, however, is that different adhesives are made for different purposes. What is more, different adhesives have different strengths.
And of all the adhesives, synthetic resin glues are considered the toughest. And durable. They harden so well and smoothly. They can be used on different hard surfaces including metals. Synthetic glue can also stick both porous and non-porous materials. What is more, they become rock hard and would not shrink at any one time. If you need them for your sticking; you will always find them in tubes.
Then there are 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 commonly used in electric cabling.
Then there are the adhesives that are derived from the animal products. Frequent 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. You can use animal adhesive on fabrics, cards, and even papers.
Then there are adhesives that are designed to be used as aerosols. They are typically available in low or moderate viscosity. They are applied or sprayed on the surface fast so that the droplets land on the intended surface before they dry up. Majority of these aerosols adhesives are dispensed using a spray gun or an aerosol can.
Designers often make use of these aerosol adhesives to cause an immediate bond on the surface which they can reposition before it gets sticky. One great advantage with the aerosol adhesive is that they are clear, stainless, and are very fine mist especially when they are sprayed. Even such a brittle paper can be sprayed, and it will not tear. One key drawback is that you should always spray in a ventilated area as the aerosol is highly combustible. 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.
