Types Of Adhesives And Their Application
Adhesives, Loctite, paste or glue are materials that are used for sticking. Adhesives play key roles in everyday life. It is almost as if daily activities will be paralyzed if these adhesives are not available.
There are kinds 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, the different adhesives that are there have varying levels of strengths.
And of all the adhesives, synthetic resin glues are considered the resilient. And long-standing. 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. They also 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 also the polyester resins. They are pretty much like epoxies but will not shrink when used. When they hardened, they are very good for glass fiber.
Another commonly used adhesive is the silicone. Silicones work best in high temperatures. They are also resistant to water and are often used for electric cabling.
There are also adhesives that are derived from parts of animals. Frequent ones are the glue cakes that are made from the hides and bones. Then there is the famous gelatin that is even used for cooking. You can use animal adhesive on fabrics, cards, and even papers.
There are also the adhesive in the form of aerosols. They are usually 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. Majority of these aerosols, adhesives are dispensed with the help of 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 payback that you gain by using an aerosol adhesive is that they are clear, free from any stain and are very fine mist 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 damages in your lungs.
The polyester resins are utilized in glass, plastics, and metals. Cellulose adhesives are 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.
