Product Name: 2-METHYL-1,5-PENTANEDIAMINE Product Code: MPMD CAS No.: 15520-10-2 Product Category: Aliphatic Diamine / Amine Intermediate 1. Product Information Item Information Chemical Name 2-METHYL-1,5-PENTANEDIAMINE Product Code MPMD Other Names 1,5-DIAMINO-2-METHYLPENTANE；2-Methylpentamethylenediamine；1,5-Pentanediamine, 2-Methyl CAS No. 15520-10-2 Molecular Formula C6H16N2 Molecular Weight 116.20 g/mol Category Aliphatic diamine compound     2. Product Description MPMD is an aliphatic diamine compound containing two primary amine functional groups. According to the company TDS, MPMD has unique properties such as low viscosity, high elasticity and good compatibility. It can be used in coatings, polyurethane, polyurea, hot melt adhesives, high performance polyamides, neutralizing or buffering agents and metalworking fluids. Using dibasic acids, high molecular weight polyamine polymers and copolymers are generated. Compared with polymers and copolymers prepared using hexamethylenediamine compounds, these compounds have low melting points and low crystallinity.   3. Structure Features and Key Advantages 1. Two primary amine functional groups MPMD contains two primary amine functional groups. According to the TDS, the two primary amine functional groups have different reactivity, which supports formulation design and reaction rate adjustment. 2. Low viscosity and good compatibility MPMD provides low viscosity and good compatibility, which helps improve mixing, flow and processing operation in resin systems. Application performance should be confirmed by testing in the final formulation. 3. Elasticity improvement According to the TDS, MPMD can improve the elasticity of polyamine hot melt adhesives and extend their air exposure time. The epoxy resin curing agent produced with 2-methylpentanediamine has a low adduct viscosity and can promote the improvement of resin formulation through its elasticity.   4.
