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 movie covering, eliminating the possibilities of color-layer separation and permits repositioning the covering on your model. UltraCote's unique ability to both diminish and extend make it exceptional to other coverings for walking around tight curves and wingtips.
 
Temp ranges are as follows:

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

 



Surface Preparation:
The covering task can only be as great as the finish of the surface it's applied over. In order for the covering to effectively abide by a surface, the surface should initially|initially} be smooth and tidy. Sand the model 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 unpleasant bumps. Fill spaces and damages with a high-quality filler. If using light-colored UltraCote® (such as white or yellow), use a tan-colored filler that matches the wood color to avoid the filler from revealing|revealing} through.

Pro Idea - Some expert builders “raise the grain” then sand a 2nd time with 320 or 400 grit paper for the supreme finish. After the model is sanded, use a damp fabric to clean down the model. Some modelers prefer to use a fine-mist squirt bottle filled with water to moisten the surfaces to be covered. As the surface dries, imbedded 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, producing a rough finish. Vacuum the model thoroughly and prevent touching the model with oily hands.Your model is now check outy|prepared|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 few inches larger than had to cover the wing. Remove the backing (save for later) and position 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 real temperature, here is a suggestion that will guarantee your iron is effectively set.Water boils at 212°F. Allow your iron to heat 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 until the water simply starts to boil off. This technique is remarkably accurate and is typically within 10° (of the precise application temperature of 220).


Adding 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). Gently pull the covering toward the root and toward the suggestion, as you work the iron from the center of the spar to the root and suggestion of the wing. Press gently with the iron, allowing the heat (not pressure) to activate the adhesive and bond the covering to the high point. Ideally, the covering will naturally lay flat against the whole surface 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 trailing edge and then to the leading edge as revealed, using the iron at 220°F. If a wrinkle establishes, the covering can be thoroughly lifted and reapplied.


Covering an Open-Structure Wing:
If covering an open-structure wing, work from the spar toward the trailing edge, gently sliding the iron (set at 220°) toward the trailing edge with the iron contacting 2 ribs. Using your iron, adhere the covering to the staying ribs, pursuing the suggestion and the root. Now complete the open structure leading edge, using the 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. Using 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 wrap around the leading and trailing edge of the wing. Now seal the leading and trailing edges safely with the covering iron.


Wing Idea:
Depending on the amount of the curvature of the wing suggestion, high heat (approximately 350°F) may be had 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 suggestion while applying heat with the iron. Remember, UltraCote® can be thoroughly lifted and repositioned to assist get rid of wrinkles. This feature is advantageous, particularly when covering dramatically curved wing tips. Continue working, pulling, and heating the covering around the suggestion until the covering is past the center of the suggestion. It may be necessary to increase the temperature of the iron to achieve higher shrinking to get rid of all wrinkles. Trim 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 Hanger 9 ProTrim Sealing Tool is really useful and results in an expert finish.


Covering the Top of the Wing:
Using the backing 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. Make certain to cut a leading panel, making certain that the adhesive is on the right side. Apply the covering to the top of the wing using the same strategies as described in actions 3 through 6. Make certain that the covering overlaps a minimum of a 1/4" when trimming the edges and safely seal the edges with the iron.


Shrinking the Covering:
Now it’s time to diminish the covering. With the iron set to 300°F, apply heat using the same pattern used to apply the covering starting at the spar and working outward. It may be necessary to increase the temperature to 320°F to obtain rid of persistent wrinkles. Utilize the minimum amount of heat necessary to tighten the covering.

Pro Idea - Usage heat, not pressure, to diminish the covering taught. If pressure is applied, gouges can be pressed into the wood. Let heat, not pressure, do the work.
Alternate Method: A heat gun can also be used to diminish the covering. This works particularly well over an open structure. It can also be used over a solid structure if a Hanger 9 Covering Glove™ is used to gently press the covering to the surface after heat is applied.


Covering Fuselages and Other Solid Surface areas:
The method for covering fuselages and other easy 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 outward from the center, bonding the covering to the surface. Trim and seal the edges. About 1/4" or more overlap is suggested when applying the next piece of covering. Diminish the covering, using the same technique as described above.

Important: Even if you're experienced in applying other brand names of covering, it’s important to read the following instructions. UltraCote® includes a unique multi temperature controlled adhesive and shrinkage system that makes attaining expert covering results easy.

Multi-Temperature Control System:
Comprehending the benefits of this system and ways to use it will make covering with UltraCote® easy and assist to make sure expert results. When using UltraCote®, there are three essential temperatures to be mindful of.

Application Tempature-220°F (100°C):
At 220°, the adhesive on UltraCote® ends up being active, allowing the covering to be connected to the model.While 220° will fully bond the covering to the model, it is well below the temperature that triggers UltraCote® to diminish. This is precisely what's needed when very first attaching covering to the model to avoid the covering from distorting.



Pro Idea - Numerous expert builders mark this temperature on their covering iron with a marker or striping tape for fast referral, as this temperature is used often whenever putting on covering.



Shrink On-Set Temperature-300°F (134°C)
At 300°F, UltraCote® starts to diminish. 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 diminish 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 optimum shrinking point. Raising the temperature above this point will not trigger more shrinking.


The rate of shrinkage is not straight in proportion to the temperature. The chart to the right demonstrates how most of the shrinking rate occurs between 300°F and 330°F. At higher temperatures UltraCote® continues to diminish however at a much slower rate. The tiniest amount of shrinking occurs between 340°F and 350°F. This is useful to keep in mind when shrinking and tightening covering.


Important:As Soon As UltraCote® is shrunk to a particular temperature, a greater temperature should be used to more diminish 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 achieve more shrinkage.

Pro Idea - Constantly use the minimum heat necessary to get rid of wrinkles when tightening the covering, hence allowing a lot of shrinkage/temperature range staying if it's necessary to more diminish the covering.



Handy Hints

Multiple Colors:
When applying 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 diminish and misshape the straight edge.

Use a Sealing Iron Sock:
A covering sock put over the iron is highly suggested, as it generally avoids the surface of the iron from scratching. The sock absorbs heat and will need the user to work slower or to turn the warm up 10%. Practically all expert builders use covering socks. Hangar 9™ deals among the very best that features muslin on one side to avoid heat damage and soft cotton on the other side for a soft, scratch-free finish.

Dryer is Much better:
Wood naturally absorbs moisture.Wood designs actually grow and diminish slightly throughout various seasons. This can be experienced by taking a trip from the humid Midwest of the United State to the dry deserts of Las Vegas. After a few days in the desert, the model establishes covering droops due to model shrinking. It is recommend that you cover the model in a dry climate if possible. Putting the model in a room with a dehumidifier for several days before covering the model may avoid the covering from drooping due to model shrinkage.

Painting:
UltraCote® will accept most kinds of polyurethane, epoxy, and automobile acrylic paints. It’s suggested that the surface be scuffed with 000 steel wool or Scotch® intense pads then thoroughly cleaned with acetone or thinner before painting. Model Dope or butyrate-based paint are not compatible with UltraCote®.

Bubbles and Imperfections:
Sometimes the extreme heat from the sun can trigger bubbles and blemishes in the covering, particularly when using dark colors. To get rid of these, heat the bubbled area using a heat gun to expand the air under the covering, triggering the bubble to increase. Quickly pop the bubble using a needle then clean the area using a cold, damp wash fabric. The damp wash fabric rapidly cools the area, allowing the covering to re-adhere. It may take several tries to entirely get rid of the bubble/blemish, however this technique works great.

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