Adhesives are materials applied between two substrates (both metallic and nonmetallic substances) for gluing or bonding purposes. Today, adhesives have replaced bolts and rivets in several applications such as buildings, automobiles, and aerospace. Adhesives provide scope for innovating the design and shape of products. They are widely used in the automobile industry to make lightweight and fully efficient vehicles.

Nanofiltration (NF) is a membrane filtration-based process or liquid-separation technology that uses membranes with nanometer-sized pores to remove dissolved contaminants. NF membranes have pore sizes ranging from 1-10 nanometers, which is smaller than membranes used in microfiltration and ultrafiltration. However, the size of NF membranes is larger than RO membranes. NF membranes offer high rejection of multivalent ions (such as calcium) and low rejection of monovalent ions (such as chloride). The nanofiltration technology is used to recycle wastewater due to high flux rates and relatively lower energy consumption than RO technology. In addition, NF is often employed in the manufacturing process for pharmaceuticals, textiles, dairy products, and baked goods.

Degreasers are used to clean various types of equipment and machinery; they are used to clean or remove dirt, dust, and any foreign particles, and can be used for both residential or industrial purposes. Industrial degreasers are used to clean motor parts, machinery, and heavy equipment that are used in various end-user industries. They are powerful solvents that can handle numerous types of manufacturing parts, components, and heavy machinery. Hazardous substances such as paints, grime, grease, oil, lubricants, dirt, dust, corrosion, and sticky films that get accumulated over machines can easily be removed by using industrial degreasers. Industrial degreasers will remove these foreign particles as well as increase the shelf life of machines or equipment.

Oleochemicals are chemicals derived from plant and animal oils. Oleochemicals include the formation of basic oleochemical substances like fatty acids, fatty alcohols, glycerine, methyl esters, and others. Intermediate chemical substances produced from the basic oleochemical substances include alcohol ethoxylates, alcohol sulfates, alcohol ether sulfates, quaternary ammonium salts, monoacylglycerols, diacylglycerols, structured triacylglycerols, sugar esters, and other oleochemical products. Oleochemicals are biodegradable, eco-friendly, and less toxic. The major oleochemicals are fatty acids, fatty alcohols, methyl esters, and glycerines, which are referred to as basic oleochemicals.

Over the past years, cleaning products have become part and parcel of a consumer’s life. Consumer awareness is also growing every year, which is why manufacturers are focusing on elevating the quality of cleaning products with the best possible environmental conditions. Today's consumer is not just concerned about maintaining hygiene or cleanliness at a personal level but also keen on reducing the chances of infections in his/her surroundings. So, to fulfill the hygiene needs at home as well as at commercial places, different ingredients are used in cleaning products.

Desalination is a procedure that helps in separating dissolved salts and other minerals from seawater, brackish water, and groundwater & surface water. It is deemed as an alternative sustainable supply of freshwater with the requisite quality and quantity. The key advantage of desalination is that it can provide high-quality drinking water for consumption in areas of water scarcity. Desalination addresses diminishing freshwater supplies as the countries are looking for solutions to deal with water scarcity caused by climate change, industrial development, pollution, and population growth. Innovations in technology have improved energy efficiency, where larger economies of scale have also aided in reducing costs, thereby assisting in the growth of the overall water desalination market.

Plastics have become an inseparable part of modern lifestyle since their formation. Plastics are used for packaging, building and construction, automotive, consumer goods, electronics, and medical devices. To make plastics usable and to increase their processability, plastic additives are required to modify polymer resin. This helps in enhancing several characteristics that manifold the value of plastic materials. Various types of additives such as flame retardants, heat stabilizers, lubricants, and slip additives, blowing agents, antistatic agents, antioxidants, and light stabilizers are used for the modification of polymer resins.

UV curable coatings are based on UV curing technology that makes use of ultraviolet light to initiate the reaction. UV-based coating formulations can be applied to a variety of substrates such as paper, wood, metal, and plastic. The technology requires very less space and lesser curing time than conventional technologies. In many cases, the amount of heat generated while curing is also less; therefore, heat-sensitive substrates can also be coated. These UV coatings come in a variety of types such as 100% solids, water-based, solvent-based, pigmented, clear, and various gloss formulations.

Oral health is a vital part of overall general health, and therefore, good oral health is indicative of overall wellness. Most diseases start from the oral site and spread to the entire body. Although some of these oral infections are preventable, some are not, and therefore, taking care of oral health is of paramount importance. The lack of proper oral hygiene accelerates the growth of microbes and causes various dental disorders, such as halitosis and dental caries.

Wood-based products are often prone to corrosion, destruction, and stains. A glossy wood coating prevents damage and increases the durability of wooden products, thus boosting their sales. It also makes wooden products desirable and aesthetically pleasing, thus luring customers into buying them. There are many wood coatings, including exterior wood coating, waterborne wood coating, radiation cure coatings, and wood finishing. Exterior wood coatings are extremely important in the furniture industry as they offer a good finishing and make furniture sturdy.

Disinfecting is a procedure that uses chemicals/disinfectants to kill germs on surfaces and objects. Some common disinfectants include bleach and alcohol-based solutions. Disinfectants are usually left on target surfaces and objects for a certain period to kill germs. Also, the task of sanitizing can involve either cleaning or disinfecting or both. According to the Center for Disease Control and Prevention (CDC), sanitizing refers to lowering the number of germs on the surface to a safe level. The safe level depends on public health standards or requirements at workplaces, such as healthcare facilities. Some common ways of disinfecting and sanitizing include mopping a floor using a mop with disinfectants and water, disinfectant wipes or hand sanitizers, and others.

Silicone sealants are employed to seal objects/surfaces that may be exposed to extreme environments, weathering, temperature, or movement for a prolonged period. Sealants are effective solutions that are elastic, flexible, durable, and reliable. Hence, they can be put to application in harsh conditions, ranging from construction, space, electronics, automotive, medical, and packaging. Silicone sealants are composed of silicone as a primary ingredient. The other essential components that provide silicone sealant their inherent properties are polymers, plasticizers, active reinforcing fillers, passive non-reinforcing fillers, cross linkers, and special additives. Silicone sealants based on their specific application can be readily modified using biobased materials. Through the addition of specific additives and fillers, they can be imparted enhanced electrical/thermal conductivity, resistance to fluctuation temperatures, and optical clarity, among others.

Over the last few years, personal care products have become part and parcel of consumer’s life. It includes array of product such as soaps, liquid soaps, hair gel, hair oil, shampoos, anti-aging face creams, sunscreen products and others. Chemicals used in personal care products range from basic metallic salts and fatty acids used in ordinary bath soaps to the high-end cosmeceuticals that offer beautifying properties of cosmetics with useful benefits of pharmaceuticals and chemicals.
