Types Of Adhesives And Their Application

Adhesives, Loctite, paste or glue are materials that are used to stick items. Adhesives play crucial roles in our 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 hard locating these precious items for your use. What you should need to remember, however, is that different adhesives are made for different purposes. What is more, different adhesives have different strengths.

And of all the adhesives, synthetic resin glues are considered the toughest. And long-standing. 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. They also become hardened 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 resemble epoxies but will not shrink easily. When they hardened, they are ideal for glass fiber.

Another widely 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 obtained from various animal parts. 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.

There are also the adhesive in the form of aerosols. They are usually 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. Most of these aerosols adhesives are discharged using 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 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 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 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.
