A typical place betterment shop carries many different adhesives for many different applications. The interaction of molecules is known as intermolecular bonding, or secondary bonding. Primary bonding, besides known as intramolecular bonding, is the interaction of atoms within a molecule and includes covalent and polar covalent bonding.

Similarly, Gooch defined adhesives as substances capable of holding together materials by surface attachments in a functional manner that resists separation, and they include paste, glues, mucilage and cement This report will discuss the chemistry, properties and industrial uses of adhesives and glues.
Chemistry of adhesives and glues Adhesives consist of different chemical components which have specific functions inside an adhesive as a well as the main polymer providing the adhesive properties.
Moreover, there are other compounds as the fillers and the additives that provide to the adhesives specific properties Miller According to Petrie, adhesives are polymers that can be categorised into two major classifications according to the way in which curing and crosslinking reached; physical curing adhesives, chemical curing adhesives The chemical curing adhesives often reach their cross-link or cured by series of chemical reactions such as polymerization or polycondensation, polyaddition that internally occurs between monomers Gooch The composition of such adhesives include the following compounds; monomers, prepolymers, fillers, pigments, and additives Miller Petrie pointed out that the base of the chemical curing adhesives is on a series of monomers that chemically react with them to produce structures of polymers with elastomers, thermoplastic or thermosets properties The physical curing adhesives contain already formed polymer but needs an energy such as pressure or heat to process the curing and adhesion process.
The composition of these adhesives include the following compounds; polymer, fillers, pigments and additives para 4. Properties of adhesives and glues According to Gooch, adhesives and glues have excellent physical, mechanical and chemical properties, and that is the reason of their use in performing joins requiring certain levels of security and strengths The properties of the adhesives and glues include; High temperature resistance above c, and for the adhesives that are silicone-based, it can go up to C High resistance to impact loads and against fractures.
Adhesives are moisture durable and are resistant to strength with exposure to liquid water and high humidity.
The adhesives and glues can wet and spread on the surfaces of the adherents being joined The mechanical properties of adhesives and glue include resistant to abrasion, flexible and toughened, dimensional stability, and low stress, resistant to vibration, shock and impact.
Adhesives are also chemically resistant, and this enables them to withstand degradation from solvents, diesel fuel and other chemicals. Industrial uses of adhesives and glues Adhesives and glues are used in different industrial applications. This also implies that there is a vast range of industrial adhesives for every industrial application, and they range from thread locker adhesives, structural adhesives, and pressure sensitive tape adhesives Miller Adhesives are designed to be used in industries and also to aid in manufacturing of materials and components.
Some of the industrial uses of adhesives as pointed out by Miller para 4 include: Metal bonding applications especially the weather tight flexible and elastic adhesives and glues2.
Consumer packaging of goods 3.
|Science Topics for Research Papers | Owlcation||Our entire universe is made up of matter which is constantly changing forms and evolving into other forms of energy.|
|Molecular biology & Genetics Topics||See Article History Adhesive, any substance that is capable of holding materials together in a functional manner by surface attachment that resists separation. Inorganic substances such as portland cement also can be considered adhesives, in the sense that they hold objects such as bricks and beams together through surface attachment, but this article is limited to a discussion of organic adhesives, both natural and synthetic.|
Rapid fixturing of plastics, rubber and Meta substrates in manufacturing operations such as the superglue 4. Lightweight materials bonding 6. School, home and office materials fixing and bonding Conclusion In conclusion, the report discussed the chemistry, properties and industrial uses of adhesives and glues.
The chemistry of adhesives and glues comprises of different components which has different functions in providing adhesive properties. Moreover, adhesives and glues have diverse properties ranging from mechanical, physical, chemical, and environmental which enables it to be applied in different industrial uses.
The industrial usage of adhesives and glues in different industries such as wood work, metal work, transport, schools and homes has been possible because of the diverse properties. References Petrie, Edward M.

Redox is the term used to label reactions in which the credence of an negatron (decrease) by a stuff is matched with the contribution of an negatron (oxidization). The developments of hot-melt adhesives, waterborne adhesives, and radiation-curable adhesives are vivid examples of successes in solving some of the problems.
As chemists, our hatural desire is to understand how those new adhesives and Pages: A bachelor's degree in chemistry or a related discipline usually is the minimum educational requirement for entry-level chemist jobs. Most research jobs in chemistry require a master's degree or, more frequently, a PhD.
