Types Of Adhesives And Their Application
Adhesives, Loctite, paste or glue are materials that are used to stick items. Adhesives play key roles in everyday life. It is almost as if our daily activities will be paralyzed if these adhesives are not available.
There is a wide range of varieties of adhesives that are available on the market. You should not find it any difficulty locating them for your purchases. What you always need to remember, though, is that all adhesives are designed for use with different services. 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, including metals. Synthetic glue can also fix 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 can 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.
Another widely used adhesive is the silicone. Silicones can stand high temperatures. They are resistant to water and are frequently used in electric cabling.
Then there are the adhesives that are derived from the animal products. 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. You can use animal adhesive on fabrics, cards, and even papers.
Then there are aerosols adhesives as well. They are typically 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 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 major disadvantage is that you need to spray in a ventilated area as the substance is highly flammable. You also need to be cautious not to inhale the fumes – you will expose your health to hazards.
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 fix metals, stones, glasses, plastics and even wood. Vegetable glues will glue papers and cards.
