Profilm Transparent Yellow (model number 21-039-002) is a high-quality, 2-meter roll of iron-on polyester covering designed for R/C model aircraft. It is a transparent yellow, often categorized under Oracover, that is designed for easy application and durability. 

Key Features and Characteristics:

• Application: It is "temperature uncritical," meaning it is easy to apply without specialized skills.
• Adhesion: Features a high-quality adhesive that bonds securely to wood, and it is safe to use on foam as the adhesive activates at roughly 80°C.
• Durability: Resistant to fuel, it offers high tensile strength and resists punctures.
• Finish: Provides a smooth finish that resists sagging or wrinkling in the sun. It is also paintable.
• Repositioning: Allows for re-positioning during application without the risk of the color layer separating from the adhesive layer, thanks to its multi-layer construction.
• Specifications: The roll is 2 meters in length. 

This covering is designed to provide a transparent yellow finish for model aircraft, offering both structural strength and aesthetic appeal.
