Aliphatic Amines are highly-reactive curing agents, consisting of a short distance between the active sites. They are blended with epoxy molecules, which allows them to obtain densely cross-linked networks. Aliphatic amines are very common chemicals in the pharmaceutical industry and occupational settings. Most aliphatic amines have irritant, corrosive properties that can result in being very harmful to the skin, also resulting in chemical burns. Using Aliphatic amines in the curing agents provides several benefits that include a high degree of chemical resistance. It helps to achieve low viscosity, high heat distortion temperatures, and low color. It also prevents blushing in the longer time frame and increases the film performance. The aliphatic compounds are formed by the replacement of one or more hydrogen atoms in ammonia with one or two-three alkyls. All of the aliphatic amines are basic in solution, and they also form salts. There are a variety of things in which aliphatic amines are used. These include catalysts, emulsifiers, synthetic cutting fluids, and flotation agents.
Diethylamine is widely used in the metal industry as it is a corrosion inhibitor and is also a solvent in the petroleum industry.

Usage Of Aliphatic Amines In Curing Agents

There is a range of products that require the use of a hardener with some distinctive features. Our curing agents that are based on a backbone convey toughness into a final thermoset. This toughness works together with other features of the hardener in increasing the impact resistance, crack resistance and substrate adhesion to different surfaces. Our hardeners, including aliphatic amines, are particularly used to make the solvent-free coating. They are highly used in civil engineering systems to help make their ideal flooring, and with the patch repairs, to build highly chemical resistant tank linings that can be used to store different types of solutions. They are also used in the making of adhesives, composites, and molding. Our hardeners are also used as accelerators for other amine curing agents.The aliphatic amines hardeners are also used in casting, molding. These hardeners provide excellent water resistance, combined with toughness, and are also used in the formation of primer coatings, moisture barrier coatings, and electrical potting.

The amines can result in damage to the skin if they come into contact with the skin or are splashed in the eyes. Other than this, they have no toxic properties. The Lower aliphatic amines also occur in a large number of foods, precisely fish, as they are also present in the body tissues. Some aliphatic amines may react with nitrate or nitrite to form nitroso compounds, which are referred to as potent carcinogens in animals. Butylamine is one of the most important isomers available commercially. Its vapors have adverse effects on the central nervous system of animals and also have an intense effect on humans. It can also lead to depression and even cause unconsciousness. Butylamine is actively absorbed through the skin and is readily metabolized.
