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 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. You should not find it hard locating these precious items for your use. What you need to remember, however, is that different adhesives are designed for use on different surfaces. 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 durable. They harden so well and smoothly. They can be used on different hard surfaces as well 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 pretty much like epoxies but will not shrink when used. When they hardened, they are ideal for glass fiber.
Silicones are also commonly used adhesives. Silicones can stand 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 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 usually 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 with the help of a spray gun or an aerosol can.
Designers frequently take advantage of 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 applied in the 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 fix metals, stones, glasses, plastics, and wood as well. Vegetable glues will glue papers and cards.
