2-Methylpentamethylenediamine

It provides toughness, low blush, uniform finish, high gloss, and improves UV stability.

[3][4] Its derivatives like aspartic esters, secondary amines, aldimines and ketoimines serve as curatives in polyurea systems.

It lowers melting point, improves surface appearance, increases abrasion resistance, and dye uptake.

It also reduces water absorption, gelling, melt and quench temperatures.

[7] It can cause burns, is corrosive to skin, harmful when swallowed, and it can cause pulmonary edema and acute pneumonitis when inhaled in high concentrations.
