Types 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 many varieties 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 strongest. And long-lasting. They harden so well and smoothly. They can be used on different hard surfaces as well metals. Synthetic glue can also fix both porous and non-porous materials. They also become hardened and would not shrink at any one time. If you need them, you will always find them in tubes.
Then there are the polyester resins. They resemble epoxies but will not shrink easily. When they hardened, they are very good for glass fiber.
Silicones are also commonly used adhesives. 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, 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 available in low or moderate viscosity. They are usually applied on a surface by spraying on the surface fast so that they adhesive 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 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 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 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 fix metals, stones, glasses, plastics, and wood as well. Vegetable glues will glue papers and cards.
