substances in engineering

An adhesive is an essential material in the construction process. Nails and other forms of binding are not appropriate for use in most surfaces. The liquid nature of this kind of a substance makes it ideal for bonding surfaces. Once dry, your surfaces will remain firmly intact and with a decent finish all together.

What are the various forms of Adhesives available


The making of an adhesive will depend on the intended use. Structural adhesives are made in such a manner that they can withstand a variety of elements such as high temperatures. They include epoxies and cyanoacrylates. These bonding items are also essential for aesthetic purposes such as is the case of rubber cement. Pressure sensitive adhesives are also available for use in in the bonding of wet surfaces.


Relevance of the substances in engineering


Engineering is all about design and construction of structures. For this to happen the various items used must remain intact otherwise the structure will fail. The unique bonding properties of an adhesive make it very useful for an engineer. In wooden structures, it has made it possible to minimise the use of nails and bolts. In the making of joints, an adhesive makes them tighter and in most cases even waterproof once dry. With so many applications in the construction process including aesthetics, it is one of the materials which engineers greatly rely on in their daily work.


What are the properties to look for when buying an adhesive


Adhesives are not universally ideal for all surfaces. They are specially made to suit a specific surface. Before buying one, it is crucial that you know what kind of surface you are likely to use them on. If the application is in places that experience extreme conditions such as heat or even chemicals, technical advise necessary before one makes a purchase. The expiry date of an adhesive is very important. The packaging should also be intact as exposure to air results in drying up of the substance.


Engineers advice on how to apply an adhesive


For proper bonding to take place, whoever is applying the substance needs to get it right. Make sure the surfaces to be bonded are free from dust. In case an adhesive is not meant for wet surfaces, make sure the area is completely dry as the wetness can interfere with the strength of the bond. Apply the adhesive evenly on the surface and keep the surfaces firmly in contact as the drying takes place. Allow the joint enough time to dry.


When using an adhesive, it is always important to exercise caution. Some are corrosive to the skin and require one to use protective clothing such as gloves when handling them. The fumes emitted may also be irritating to the nose if inhaled. In case your eyes or mouth comes into contact with the substances, it is wise to seek medical attention after getting first aid. Some adhesives have toxic properties which can harm sensitive parts of your body such as the eye.
