Profilm Royal Blue (specifically SKU 28-059-002 or often referred to as Royal Blue 59) is a high-quality, professional-grade iron-on polyester covering film designed for radio-controlled (R/C) model aircraft. It is produced by Lanitz-Prena and is often considered equivalent to Oracover, offering a durable, glossy finish in a rich royal blue color. 

Key Characteristics and Features:

• Dimensions: Typically available in a 2-meter roll (2MT ROLL), providing enough material for covering medium-sized models.
• Material: A versatile polyester film known for high puncture resistance and tensile strength.
• Application: Heat-activated adhesive that melts onto wooden, composite, or foam surfaces, creating a strong, long-lasting bond.
• Appearance: Features a high-gloss, vivid royal blue finish.
• No Sagging: Designed to resist sagging, wrinkling, or slackening in sunlight. 

Key Performance Benefits:

• Temperature Flexibility: Highly "uncritical" regarding application temperature, allowing for easier handling when ironed on.
• Re-positionable: Permits re-positioning without fear of color-layer separation, providing a "second chance" during application.
• Fuel Resistant: Withstands residue from glow fuel and exhaust.
• Lightweight: Offers a lightweight finish suitable for maintaining aircraft performance.
• Multi-Layer System: The adhesive layer is separate from the color pigment layer, meaning that if the film is removed, it does not leave tacky pigment residue on the structure. 

This film is ideal for creating a smooth, durable finish on RC planes and can be used on various surfaces, including Styrofoam (when applied with proper low-temperature techniques).
