Poly-Tak 855 Aircraft Fabric Cement

Poly-Tak Fabric Cement is a high-strength, fast-drying, one-part cement manufactured from a proprietary formula especially to attach polyester fabric to an airframe. It is FAA approved with the Poly-Fiber STC for use in making a 2˝ overlap cement seam on the wing leading edge and a 1˝ overlap cement seam on the balance of the aircraft, regardless of the wing loading or maximum speed (Vne).

Key Features:

• No other aircraft fabric cement has this approval
• Excellent cement for cotton, linen, and glass fiber and will adhere to most surfaces for shear load bonding
• No machine sewn or hand sewn seams are required when using Poly-Tak
• Can dry clear or opaque (white), depending on the speed of drying, thickness and how smooth is the dried surface
• Add Methyl Ethyl Ketone (MEK) when necessary to reduce viscosity due to solvent evaporation from an open container

Storage and Handling:

• Guaranteed two years unopened in protected storage under 100°F
• Not affected by freezing
• Poly-Tak should be clear. Discolored cement has been heat damaged

This professional-grade fabric cement is designed specifically for aircraft covering projects and provides reliable, high-strength bonds that meet FAA standards. Refer to the Poly-Fiber Manual for details on approved methods for cement seams.
