1,2 Propylendiamine (1,2-PDA) is an alphatic difunctional amine.
1,2-PDA is used in the production of polymers for adhesive and sealant applications.
As a building block, 1,2-Propylenediamine is a raw material for the production of polyurethane resins (polyester polyol and polycarbonate diol). It provides a balance between hardness and flexibility, adhesion, weatherability and hydrolysis resistance. It is also used as a chain extender in the production of polyurethane dispersions.
1,2-PDA is an essential ingredient for the production of elastomeric fibers. It is also used as a building block in the manufacture of medicines and plant protection products, colorants, textile auxiliaries, pigments and optical brighteners.
