Types Of Adhesives And Their Uses
Adhesives, Loctite, paste or glue are materials that are used for sticking. Adhesives are instrumental in our 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, different adhesives have different strengths.
And of all the adhesives, synthetic resin glues are considered the toughest. And long-lasting. 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 commonly used adhesive is the silicone. Silicones can withstand high temperatures. They are also resistant to water and are often used for electric cabling.
There are also adhesives that are obtained from various animal parts. 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 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 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 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 fix metals, stones, glasses, plastics, and wood as well. Vegetable glues will glue papers and cards.
