www.threebond.co.jpAmines are called monoamine, diamine, tri-amine, or polyamine according to the number of amines in one molecule. Amines are classified into aliphatic, alicyclic (Three Bond 2106), and aromatic amines according to the types of hydrocarbons involved, and the all are important curing agents for epoxy resin. Aliphatic amine (Three Bond 2103) is curing

ncerthelp.comBasic Strength of Amines Amines act as Lewis bases due to the presence of lone pair of electrons on the nitrogen atom. More the K b (dissociation constant of base), higher is the basicity of amines. Lesser the pK b‘ higher is the basicity of amines. Aliphatic amines (CH 3 NH 2) are stronger bases than NH 3 due to the electron releasing +/ effect
