Poly(propylene glycol) triamine terminated glycerol tetraether

Poly(propylene glycol) triamine terminated glycerol tetraether (CAS 64852-22-8), commercially recognized as Jeffamine T-5000, is a trifunctional polyetheramine built on a glycerol core. It features three poly(propylene glycol) amine-terminated arms.

Its three primary amine end groups enable it to act as a flexible curing agent and crosslinker in polymer systems where chain mobility and low rigidity are required. This makes it a versatile component for specialized industrial applications.

In epoxy formulations, it functions as a long-chain curing agent that imparts flexibility and impact resistance to coatings, adhesives, and structural composites. This enhances the durability of the final product under stress.

The high molecular weight and trifunctional architecture make it suitable for producing lightly crosslinked elastomeric networks. These networks are commonly used in sealants and flexible adhesive systems across various sectors.

Formulators in industrial and home care coatings use it to modify surface wetting behavior and improve substrate adhesion. It is effective in both aqueous and solvent-borne systems for superior performance.

Its amine functionality also supports rheology modification in polymer blends where controlled network density is a processing requirement. This allows for precise control over the physical properties of the polymer matrix.

The product is supplied as a viscous liquid at ambient conditions and is available in technical grade. Supply quantities range from drum to bulk depending on the specific distributor and logistics requirements.

Buyers should confirm amine hydrogen equivalent weight (AHEW) and amine value specifications when evaluating lot-to-lot consistency. This ensures the material meets the necessary standards for high-performance curing applications.
