Polypropylene glycol diamine

Polypropylene glycol diamine (CAS 9046-10-0) is a difunctional amine-terminated polyether used as a reactive building block in polymer systems.

Where is Polypropylene glycol diamine used?

• Epoxy coatings: flexible curing agent improving impact resistance and elongation
• Protective and floor coatings: durability
• Polyurethane and polyurea: chain extender tuning mechanical properties and processing in spray-applied membranes
• Adhesives: structural and elastic bonding systems with controlled flexibility
• Construction composites and grouts: toughened resin matrices with improved crack resistance
• Terminal amine groups enable direct participation in curing and crosslinking reactions.

Good to know: Molecular weight, typically 230 to 4000 g/mol, determines amine equivalent, reactivity, flexibility and curing speed. Specifications are defined by amine value and viscosity.
