Types Of Adhesives And Their Application
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 daily activities will be paralyzed if these adhesives are not available.
There are kinds of adhesives that are available on the market. It should not be difficult for anyone to locate these precious items for their use. What you need to remember, however, is that different adhesives are designed for use on different surfaces. 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 strongest. And long-standing. They harden so well and smoothly. They can be used on different hard surfaces, including metals. Synthetic glue can also stick both porous and non-porous materials. They also become rock hard 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 are almost like the epoxies but will not shrink easily. When they hardened, they are ideal for glass fiber.
Silicones are also commonly used adhesives. Silicones work best in high temperatures. They are resistant to water and are commonly 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.
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 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 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 damages in your lungs.
The polyester resins are applied in the 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 repair metals, stones, glasses, plastics as well as wood. Vegetable glues will glue papers and cards.
