Overview

Hangar 9 UltraCote® is a high tech polyester covering that features a unique multi temperature-controlled adhesive and shrinkage system, making it flexible and easy to apply. A patented polymerizing procedure completely fuses the color to the polyester film covering, eliminating the possibilities of color-layer separation and allows rearranging the covering on your design. UltraCote's distinct ability to both diminish and extend make it exceptional to other coverings for going around tight curves and wingtips.
 
Temp ranges are as follows:

Adhesion to wood starts at 200 to 220 degrees F.
Shrinkage beginning starts at 300 degrees F.
Maximum shrinkage is at 350 degrees F.



 



Surface area Preparation:

The covering task can only be as excellent as the surface of the surface area it's applied over. In order for the covering to properly adhere to a surface area, the surface area should first be smooth and tidy. Sand the design utilizing a sanding block and gradually finer sandpaper, with the final sanding being done with 320 grit paper. Vacuum away all of the dust, as specks of dust under the covering will leave undesirable bumps. Fill spaces and dents with a top quality filler. If utilizing light-colored UltraCote® (such as white or yellow), use a tan-colored filler that matches the wood color to avoid the filler from showing through.


Pro Idea - Some expert builders “raise the grain” then sand a second time with 320 or 400 grit paper for the ultimate surface. After the design is sanded, use a moist cloth to clean down the design. Some modelers choose to use a fine-mist squirt bottle filled with water to dampen the surface areas to be covered. As the surface area dries, inserted wood fibers in the surface area will “stand up.” When dry, sand the surface areas once again utilizing 320 or 400 grit paper. Raising the grain now and sanding it off will avoid the grain from raising later on under the covering, developing a bumpy surface. Vacuum the design thoroughly and prevent touching the design with oily hands.Your design is now all set for covering!



Trim Film to Size:

Start by covering the bottom of one wing half. Using scissors or sharp hobby knife, cut a piece of UltraCote® a couple of inches larger than needed to cover the wing. Eliminate the support (conserve for later on) and put the covering with the adhesive (dull) side down, focused over the wing. Set the covering iron to the application temperature of 220°F.


Pro Idea - If the iron you're utilizing does not show the real temperature, here is an idea that will ensure your iron is properly set.Water boils at 212°F. Allow your iron to warm up at a medium setting. When the iron reaches its stabilized temperature, carefully pour a couple of drops of water on the iron's surface area. Adjust the temperature until the water simply starts to boil off. This method is remarkably accurate and is generally within 10° (of the precise application temperature of 220).



Tacking Covering to Spar:

Tack the covering to the spar or the peak of the wing, utilizing your iron as revealed (an iron sock is highly recommened). Carefully pull the covering towards the root and towards the tip, as you work the iron from the center of the spar to the root and tip of the wing. Press carefully with the iron, permitting the heat (not pressure) to activate the adhesive and bond the covering to the peak. Ideally, the covering will naturally lay flat against the whole surface area with a minimum of wrinkles.



Covering a Solid-Sheeted Wing:

If covering a solid-sheeted wing, work from the center of the spar outward to the tracking edge then to the leading edge as revealed, utilizing the iron at 220°F. If a wrinkle develops, the covering can be carefully raised and reapplied.



Covering an Open-Structure Wing:

If covering an open-structure wing, work from the spar towards the tracking edge, carefully moving the iron (set at 220°) towards the tracking edge with the iron calling two ribs. Using your iron, adhere the covering to the remaining ribs, working toward the tip and the root. Now finish the open structure leading edge, utilizing the very same method. If the leading edge is sheeted, then follow the method listed above under “Covering a Solid-Sheeted Wing.”



Sealing the Edges:

With the iron set to 220°F, seal the leading and tracking edges. Using a straight edge and a sharp #11 hobby knife, carefully cut the excess covering from the leading and tracking edge, permitting a minimum of a 1/4" overlap to wrap around the leading and tracking edge of the wing. Now seal the leading and tracking edges firmly with the covering iron.



Wing Idea:

Depending on the quantity of the curvature of the wing tip, high heat (approximately 350°F) may be needed to diminish and extend the covering to get rid of all the wrinkles. Preset the iron to 300°F. Pull and extend the covering around the wing tip while using heat with the iron. Remember, UltraCote® can be carefully raised and rearranged to help get rid of wrinkles. This function is beneficial, especially when covering sharply curved wing suggestions. Continue working, pulling, and warming the covering around the tip until the covering is past the center of the tip. It may be required to increase the temperature of the iron to accomplish greater shrinkage to get rid of all wrinkles. Cut the excess covering utilizing a #11 hobby knife, then reseal the covering on the wing tip.


Pro Idea - If sealing the covering in tight locations such as corners or fillets, utilizing the Hanger 9 ProTrim Sealing Tool is extremely useful and leads to a professional surface.



Covering the Top of the Wing:

Using the support from the wing panel that you simply covered as a design template, cut a piece of UltraCote® to be applied to the top of the wing.
