Solving Thermoplastic Bonding Challenges in Aerospace Interiors With High-Performance Polyurethane FST Adhesives

The use of thermoplastics in aircraft interiors is significantly growing due to their lightweight and sustainability benefits, but reliable, compliant bonding remains a key challenge.

In this white paper, Huntsman explores how high-performance polyurethane FST adhesives can support durable thermoplastic bonding while helping manufacturers reduce long-term PFAS regulatory risk.

The paper highlights two URALANE® polyurethane adhesive systems, URALANE® 5774-1 A/C and URALANE® 5779-1 A/B, and their performance in aerospace interior bonding applications, including:

Mechanical performance (lap shear, T-peel, and tensile strength)
Environmental durability under hot/wet conditioning
FAR 25.853 flammability performance
Adhesion to thermoplastics and primed aluminum
PFAS-free compliance considerations
