Overview

Hangar 9 UltraCote® is a high tech polyester covering that features a unique multi temperature-controlled adhesive and shrinkage system, making it versatile and easy to apply. A trademarked polymerizing process completely merges the color to the polyester film covering, getting rid of the possibilities of color-layer separation and allows repositioning the covering on your design. UltraCote's distinct ability to both shrink and stretch make it superior to other coverings for walking around tight curves and wingtips.
 
Temperature ranges are as follows:

Adhesion to wood begins at 200 to 220 degrees F.
Shrinkage onset begins at 300 degrees F.
Maximum shrinking is at 350 degrees F.

 



Surface area Preparation:
The covering job can only be as good as the surface of the surface it's used|used} over. In order for the covering to effectively adhere to a surface area, the surface should {first|initially} be smooth and tidy. Sand the design using a sanding block and gradually finer sandpaper, with the final sanding being finished with 320 grit paper. Vacuum away all the dust, as specks of dust under the covering will leave unattractive bumps. Fill gaps and damages with a top quality filler. If using light-colored UltraCote® (such as white or yellow), use a tan-colored filler that matches the wood color to avoid|avoid} the filler from {showing|revealing} through.

Pro Idea - Some professional home builders “raise the grain” then sand a 2nd time with 320 or 400 grit paper for the ultimate surface. After the design is sanded, use a wet fabric to wipe down the design. Some modelers choose to use a fine-mist squirt bottle filled with water to moisten the surfaces to be covered. As the surface dries, inserted wood fibers in the surface will “stand.” When dry, sand the surfaces again using 320 or 400 grit paper. Raising the grain now and sanding it off will avoid the grain from raising later under the covering, developing a rough surface. Vacuum the design thoroughly and prevent touching the design with oily hands.Your design is now check outy|prepared|all set} for covering!



Trim Movie to Size:
Start by covering the bottom of one wing half. Utilizing scissors or sharp hobby knife, cut a piece of UltraCote® a few inches bigger than had to cover the wing. Remove the support (conserve for later) and put the covering with the adhesive (dull) side down, centered over the wing. Set the covering iron to the application temperature of 220°F.

Pro Idea - If the iron you're using does not display the actual temperature, here is an idea that will guarantee your iron is effectively set.Water boils at 212°F. Permit your iron to warm up at a medium setting. When the iron reaches its supported temperature, thoroughly pour a few drops of water on the iron's surface. Change the temperature till the water just begins to boil off. This technique is surprisingly precise and is normally within 10° (of the specific application temperature of 220).


Tacking Covering to Spar:
Tack the covering to the spar or the high point of the wing, using your iron as revealed (an iron sock is highly recommened). Carefully pull the covering toward the root and toward the idea, as you work the iron from the center of the spar to the root and idea of the wing. Press carefully with the iron, allowing the heat (not pressure) to trigger the adhesive and bond the covering to the high point. Preferably, the covering will naturally lay flat versus the entire surface with a minimum of wrinkles.


Covering a Solid-Sheeted Wing:
If covering a solid-sheeted wing, work from the center of the spar outside to the trailing edge then to the leading edge as revealed, using the iron at 220°F. If a wrinkle develops, the covering can be thoroughly raised and reapplied.


Covering an Open-Structure Wing:
If covering an open-structure wing, work from the spar toward the trailing edge, carefully moving the iron (set at 220°) toward the trailing edge with the iron contacting two ribs. Utilizing your iron, adhere the covering to the remaining ribs, pursuing the idea and the root. Now finish the open structure leading edge, using the very same technique. 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 trailing edges. Utilizing a straight edge and a sharp #11 hobby knife, thoroughly trim the excess covering from the leading and trailing edge, allowing a minimum of a 1/4" overlap to twist around the leading and trailing edge of the wing. Now seal the leading and trailing edges firmly with the covering iron.


Wing Idea:
Depending on the amount of the curvature of the wing idea, high heat (up to 350°F) may be had to shrink and stretch the covering to get rid of all the wrinkles. Preset the iron to 300°F. Pull and stretch the covering around the wing idea while using heat with the iron. Keep in mind, UltraCote® can be thoroughly raised and repositioned to help get rid of wrinkles. This feature is helpful, especially when covering dramatically curved wing pointers. Continue working, pulling, and warming the covering around the idea till the covering is past the center of the idea. It may be necessary to increase the temperature of the iron to attain higher shrinking to get rid of all wrinkles. Cut the excess covering using 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, using the Wall mount 9 ProTrim Sealing Tool is really practical and results in a professional surface.


Covering the Top of the Wing:
Utilizing the support from the wing panel that you just covered as a design template, cut a piece of UltraCote® to be used to the top of the wing. Make certain to cut a top panel, making sure that the adhesive is on the appropriate side. Apply the covering to the top of the wing using the very same techniques as described in steps 3 through 6. Make certain that the covering overlaps a minimum of a 1/4" when trimming the edges and firmly seal the edges with the iron.


Shrinking the Covering:
Now it’s time to shrink the covering. With the iron set to 300°F, apply heat using the very same pattern used to apply the covering beginning at the spar and working outside. It may be necessary to increase the temperature to 320°F to obtain rid of stubborn wrinkles. Use the minimum amount of heat necessary to tighten the covering.

Pro Idea - Use heat, not pressure, to shrink the covering taught. If pressure is used, gouges can be pushed into the wood. Let heat, not pressure, do the work.
Alternate Approach: A heat weapon can also be used to shrink the covering. This works especially well over an open structure. It can also be used over a solid structure if a Hanger 9 Covering Glove™ is used to carefully press the covering to the surface after heat is used.


Covering Fuselages and Other Strong Surfaces:
The method for covering fuselages and other simple flat surfaces corresponds covering a solid wing. Start with the bottom, then sides, and lastly the top. Initially, tack the center of the surface down using an iron set to 220°F.Work outside from the center, bonding the covering to the surface. Cut and seal the edges. About 1/4" or more overlap is advised when using the next piece of covering. Shrink the covering, using the very same technique as described above.

Important: Even if you're experienced in using other brands of covering, it’s important to read the following directions. UltraCote® incorporates a unique multi temperature controlled adhesive and shrinkage system that makes accomplishing professional covering outcomes easy.

Multi-Temperature Control System:
Understanding the benefits of this system and the best ways to use it will make covering with UltraCote® easy and help to make sure professional outcomes. When using UltraCote®, there are 3 important temperature levels to be conscious of.

Application Tempature-220°F (100°C):
At 220°, the adhesive on UltraCote® becomes active, allowing the covering to be connected to the model.While 220° will fully bond the covering to the design, it is well listed below the temperature that causes UltraCote® to shrink. This is exactly what's required when first attaching covering to the design to avoid the covering from distorting.

Pro Idea - Lots of professional home builders mark this temperature on their covering iron with a marker or striping tape for quick reference, as this temperature is used frequently whenever placing on covering.

Shrink On-Set Temperature-300°F (134°C)
At 300°F, UltraCote® begins to shrink. This is called the Shrink On-Set point. After the covering is connected using an iron set to 220°F, the next step is to shrink the covering. This initial shrinking is finished with the iron set at 300°F.
Maximum Shrinkage Temperature-350°F (162°C)
At 350°F, UltraCote® reaches its maximum shrinking point. Raising the temperature above this point will not trigger additional shrinking.

The rate of shrinkage is not straight in proportion to the temperature. The chart to the right shows how the majority of the shrinking rate occurs in between 300°F and 330°F. At higher temperature levels UltraCote® continues to shrink but at a much slower rate. The tiniest amount of shrinking occurs in between 340°F and 350°F. This is practical to bear in mind when shrinking and tightening covering.


Important:When UltraCote® is shrunk to a particular temperature, a greater temperature should be used to additional shrink the covering. For example, if the covering was shrunk using 320°F and wrinkles start to appear/reappear, it will be necessary to use over 320°F to attain additional shrinkage.

Pro Idea - Always use the minimum heat necessary to remove wrinkles when tightening the covering, hence allowing lots of shrinkage/temperature variety remaining if it's necessary to additional shrink the covering.



Valuable Tips

Multiple Colors:
When using covering with a 2nd color, it’s important that the light color be applied first (under the dark color) to prevent the dark color from showing through. Where colors fulfill or at the edge of the covering, it is very important to not overheat this area (over 300°F), as this will shrink and distort the straight edge.

Use a Sealing Iron Sock:
A covering sock placed over the iron is highly advised, as it generally prevents the surface of the iron from scratching. The sock soaks up heat and will require the user to work slower or to turn the heat up 10%. Nearly all professional home builders use covering socks. Hangar 9™ offers among the very best that features muslin on one side to avoid heat damage and soft cotton on the opposite for a soft, scratch-free finish.

Dryer is Better:
Wood naturally soaks up moisture.Wood designs really grow and shrink somewhat throughout various seasons. This can be experienced by traveling from the damp Midwest of the United State to the dry deserts of Las Vegas. After a few days in the desert, the design develops covering droops due to design shrinking. It is advise that you cover the design in a dry climate if possible. Putting the design in a room with a dehumidifier for several days prior to covering the design may avoid the covering from drooping due to design shrinkage.

Painting:
UltraCote® will accept most types of polyurethane, epoxy, and automotive acrylic paints. It’s advised that the surface be scuffed with 000 steel wool or Scotch® intense pads then thoroughly cleaned with acetone or thinner prior to painting. Design Dope or butyrate-based paint are not suitable with UltraCote®.

Bubbles and Blemishes:
Periodically the extreme heat from the sun can trigger bubbles and blemishes in the covering, especially when using dark colors. To remove these, heat the bubbled area using a heat weapon to broaden the air under the covering, triggering the bubble to increase. Rapidly pop the bubble using a needle then wipe the area using a cold, wet wash fabric. The wet wash fabric rapidly cools the area, allowing the covering to re-adhere. It may take several aim to completely remove the bubble/blemish, but this technique works great.

Clean Up:
The adhesive can be eliminated from the iron or design using acetone or a mild thinner.
