Various Kinds Of Adhesives And Their Uses
Adhesives, Loctite, paste or glue are materials that are used to stick items. 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 kinds 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, the strength of these adhesives vary.
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 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 resemble epoxies but will not shrink easily. When they hardened, they are ideal for glass fibre.
Another commonly used adhesive is the silicone. 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. 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 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 make use of these aerosol adhesives to cause an immediate bond on the surface which they can reposition before it gets sticky. 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 your delicate 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 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 wood as well. Vegetable glues will glue papers and cards.
