Monokote
One-step heat-shrink film for model aircraft covering.
MonoKote is a lightweight plastic shrink wrap film used to cover the surfaces of model aircraft. It features a heat-activated adhesive on one side and is applied using a hobby iron and heat gun. The material is notable for being a one-step covering system, eliminating the need for multiple coating layers.

Lore & Background
MonoKote was developed as a covering material that could be cut to size and applied directly to an airframe, simplifying the finishing process. Its heat-activated adhesive bonds the film to the surface when heated with a hobby iron, and a heat gun shrinks the material taut. The name MonoKote, a registered trademark of Top Flite, refers to its one-step application method.
The material was produced by General Formulations in Sparta, Michigan. The patent for Top Flite MonoKote is held by Sidney Axelrod. After Top Flite was acquired by subsequent owners, Horizon Hobbies discontinued the product.
Unrelated to model aircraft, MonoKote is also a fireproofing material—either gypsum- or cement-based and spray-applied—owned by GCP Applied Technologies Inc. This separate trademark is registered globally, including in the United States and Canada.
Reader's Guide
MonoKote's significance lies in its role as a pioneering one-step covering film for radio-controlled aircraft, simplifying what was previously a multi-step finishing process. Its heat-activated adhesive and shrink properties allowed hobbyists to achieve a smooth, durable finish with relative ease. The material became a standard in the industry, widely used for decades until its discontinuation by Horizon Hobbies.
The legacy of MonoKote is tied to the broader history of Top Flite and its parent company Hobbico. Hobbico filed for Chapter 11 bankruptcy protection in January 2018, followed by Chapter 7 bankruptcy and liquidation in June 2018. This corporate collapse contributed to the end of MonoKote production, leaving a gap in the market that alternatives like Ultracote have since filled. Despite its discontinuation, MonoKote remains a reference point in the hobby for its innovation and widespread adoption.
