Description :

　　SY-P11 foam adhesive aviation material institute SYP11 film adhesive single component matching SY-14 adhesive film has samples

　　SY-P11 foam adhesive is a modified epoxy single component medium temperature curing film like structural adhesive with a certain degree of self adhesiveness. Can be used for metal honeycomb, non-metal honeycomb splicing, and filling and edge sealing of various components in sandwich structures. Can be used at -55~80 ℃. Used for cellular core splicing and edge connection in aircraft radar antenna covers.

　　[Product Features]

　　Appearance: Yellow carrier free strip adhesive film;

　　Curing volatile content: ≤ 1.2%;

　　Thickness: 1.65 ± 0.40mm:

　　Expansion ratio: (1.75-3.0): 1 (equivalent to an expansion rate of 75%~200%);

　　Dielectric constant after curing: 1.93;

　　Loss tangent after curing: 0.0112.

　　[Usage Process]

　　1. Surface treatment of the adhered object: 2A12T4 (formerly known as LY12CZ) aluminum alloy bonded parts or test pieces are recommended to be treated with phosphoric acid anodizing surface treatment according to HB/Z197. Aluminum alloy surface treatment can also be achieved by chromic acid anodizing or chromium chemical oxidation. Steel samples or parts can be treated with sandblasting.

　　2. Composite materials can be polished with sandpaper to a uniform roughness, and dust can be removed with a brush or cleaned. Any metal or non-metal honeycomb core material can undergo corresponding surface cleaning treatment according to process requirements, ensuring no oil pollution.

　　3. Adhesive laying: Cut the adhesive film according to the size requirements of the surface to be bonded. When laying the adhesive film, pay attention to eliminating bubbles. If the ambient temperature is too low, you can use a hair dryer to heat and stick it together, but the local temperature should not exceed 50 ℃.

　　4. Curing and insulation time and pressure: The bonding pressure is a contact pressure of 0.14MPa, and the heating rate is 1.5 ℃/min~3 ℃/min (recommended). After the temperature rises to 125 ℃± 5 ℃ (part temperature), the insulation time is 2.0h ± 0.5h, and the cooling rate after curing is 1.5 ℃/min~2.0 ℃/min. The specific curing process can be adjusted slightly according to the process of the relevant adhesive components.

　　Packaging, transportation, and storage

　　1. Packaging and transportation: Using polymer film as the isolation layer, packaged in rolls, wrapped in polymer bags, and packed into cardboard boxes or wooden crates. According to the transportation of non dangerous goods, transportation below 4 ℃ should not exceed 10 days or at room temperature should not exceed 5 days.

　　2. Storage: The foam adhesive should be stored in an environment with a temperature range of -5 ℃ to -18 ℃. The foam adhesive has an effective storage period of 12 months from the production date. Expired foam adhesive can still be used after passing the factory inspection, but the total storage period shall not exceed 24 months. The external exposure time between 4 ℃ and 28 ℃ should not exceed 5 days, and the cumulative external exposure time at room temperature should not exceed 20 days.

　　【 Application Fields 】

　　Aviation, aerospace or other civilian fields.
