Which type of adhesive is commonly used in aircraft fabric covering?

Polyurethane-based adhesives are commonly used in aircraft fabric covering due to their strong bonding properties and flexibility. This type of adhesive is particularly well-suited for the dynamic stresses experienced by aircraft, allowing for the fabric covering to adhere securely while accommodating movement and expansion that occurs with temperature fluctuations and airflow.

Polyurethane adhesives also provide good resistance to weathering, UV light, and chemicals, making them ideal for the aerospace environment where durability is critical. Additionally, they can bond well to various substrates, which is essential in aircraft construction where different materials are often used together. This adhesive's versatility and robust nature contribute significantly to the longevity and safety of the fabric covering on aircraft.

Other adhesive types, while having their own advantages, may not offer the same combination of flexibility, strength, and resistance needed for effective aircraft fabric covering applications.
