Overview

Hangar 9 UltraCote® is a high tech polyester covering that includes a unique multi temperature-controlled adhesive and shrinkage system, making it flexible and easy to use. A patented polymerizing process completely fuses the color to the polyester film covering, eliminating the possibilities of color-layer separation and permits repositioning the covering on your design. UltraCote's distinct capability to both diminish and stretch make it superior to other coverings for going around tight curves and wingtips.
 
Temperature ranges are as follows:

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

 



Surface area Preparation:
The covering job can only be as excellent as the finish of the surface area it's used over. In order for the covering to effectively abide by a surface, the surface area should {first|initially} be smooth and clean. Sand the design using a sanding block and gradually finer sandpaper, with the last sanding being finished with 320 grit paper. Vacuum away all the dust, as specks of dust under the covering will leave unsightly bumps. Fill spaces and dents with a high-quality filler. If using light-colored UltraCote® (such as white or yellow), utilize a tan-colored filler that matches the wood color to avoid|avoid} the filler from revealing|revealing} through.

Pro Pointer - Some expert contractors “raise the grain” then sand a 2nd time with 320 or 400 grit paper for the ultimate finish. After the design is sanded, utilize a wet cloth to wipe down the design. Some modelers choose to utilize a fine-mist squirt bottle filled with water to moisten the surface areas to be covered. As the surface area dries, anchored wood fibers in the surface area will “stand.” When dry, sand the surface areas once again using 320 or 400 grit paper. Raising the grain now and sanding it off will prevent the grain from raising later on under the covering, creating a bumpy finish. Vacuum the design thoroughly and avoid touching the design with oily hands.Your design is now check outy|prepared|all set} for covering!



Trim Film 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 larger than had to cover the wing. Get rid of the backing (conserve for later on) and position the covering with the adhesive (dull) side down, focused over the wing. Set the covering iron to the application temperature level of 220°F.

Pro Pointer - If the iron you're using does not display the real temperature level, 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 level, thoroughly pour a few drops of water on the iron's surface area. Adjust the temperature level up until the water just starts to boil off. This approach is remarkably precise and is typically within 10° (of the exact application temperature level of 220).


Adding Covering to Spar:
Tack the covering to the spar or the high point of the wing, using your iron as shown (an iron sock is extremely recommened). Gently 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 gently with the iron, permitting the heat (not pressure) to activate the adhesive and bond the covering to the high point. Ideally, the covering will naturally lay flat versus the entire 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 trailing edge and then to the cutting edge as shown, 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, gently moving the iron (set at 220°) toward the trailing edge with the iron getting in touch with 2 ribs. Utilizing your iron, adhere the covering to the staying ribs, pursuing the idea and the root. Now complete the open structure leading edge, using the same approach. If the leading edge is sheeted, then follow the strategy noted 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, permitting 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 securely with the covering iron.


Wing Pointer:
Depending upon the amount of the curvature of the wing idea, high heat (as much as 350°F) may be had to diminish and stretch the covering to eliminate all the wrinkles. Preset the iron to 300°F. Pull and stretch the covering around the wing idea while applying heat with the iron. Keep in mind, UltraCote® can be thoroughly raised and repositioned to help eliminate wrinkles. This function is advantageous, specifically when covering dramatically curved wing suggestions. Continue working, pulling, and warming the covering around the idea up until the covering is past the center of the idea. It may be essential to increase the temperature level of the iron to attain higher shrinking to eliminate all wrinkles. Trim the excess covering using a #11 hobby knife, then reseal the covering on the wing tip.

Pro Pointer - If sealing the covering in tight areas such as corners or fillets, using the Hanger 9 ProTrim Sealing Tool is very helpful and leads to an expert finish.


Covering the Top of the Wing:
Utilizing the backing from the wing panel that you just covered as a template, cut a piece of UltraCote® to be used to the top of the wing. Make certain to cut a top panel, making certain that the adhesive is on the proper 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 securely seal the edges with the iron.


Shrinking the Covering:
Now it’s time to diminish the covering. With the iron set to 300°F, use heat using the same pattern utilized to use the covering beginning at the spar and working outward. It may be essential to increase the temperature level to 320°F to obtain rid of stubborn wrinkles. Use the minimum amount of heat essential to tighten up the covering.

Pro Pointer - Use heat, not pressure, to diminish 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 utilized to diminish the covering. This works especially well over an open structure. It can also be utilized over a solid structure if a Hanger 9 Covering Glove™ is utilized to gently push the covering to the surface area after heat is used.


Covering Fuselages and Other Strong Surfaces:
The strategy for covering fuselages and other easy flat surface areas is identical to covering a solid wing. Start with the bottom, then sides, and finally the top. First, tack the center of the surface area down using an iron set to 220°F.Work outward from the center, bonding the covering to the surface area. Trim and seal the edges. About 1/4" or more overlap is recommended when applying the next piece of covering. Shrink the covering, using the same approach as described above.

Important: Even if you're experienced in applying other brand names of covering, it’s important to read the following guidelines. UltraCote® integrates 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 the best ways to utilize it will make covering with UltraCote® easy and help to ensure expert results. 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, permitting the covering to be connected to the model.While 220° will completely bond the covering to the design, it is well listed below the temperature level that causes UltraCote® to diminish. This is precisely what's required when very first connecting covering to the design to prevent the covering from distorting.

Pro Pointer - Numerous expert contractors mark this temperature level on their covering iron with a marker or striping tape for quick reference, as this temperature level is utilized regularly 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 Shrinking Temperature-350°F (162°C)
At 350°F, UltraCote® reaches its optimum shrinking point. Raising the temperature level above this point will not cause further shrinking.

The rate of shrinkage is not straight in proportion to the temperature level. The chart to the right shows how most of the shrinking rate happens between 300°F and 330°F. At higher temperature levels UltraCote® continues to diminish but at a much slower rate. The tiniest amount of shrinking happens between 340°F and 350°F. This is helpful to remember when shrinking and tightening covering.


Essential:As Soon As UltraCote® is diminished to a specific temperature level, a greater temperature level should be utilized to further diminish the covering. For instance, if the covering was diminished using 320°F and wrinkles begin to appear/reappear, it will be essential to utilize over 320°F to attain further shrinkage.

Pro Pointer - Always utilize the minimum heat essential to remove wrinkles when tightening the covering, hence permitting plenty of shrinkage/temperature range staying if it's essential to further diminish the covering.



Valuable Tips

Numerous 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 necessary to not overheat this location (over 300°F), as this will diminish and distort the straight edge.

Use a Sealing Iron Sock:
A covering sock put over the iron is extremely recommended, as it usually prevents the surface area 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%. Almost all expert contractors utilize covering socks. Hangar 9™ deals among the best that includes muslin on one side to prevent heat damage and soft cotton on the opposite for a soft, scratch-free finish.

Dryer is Much better:
Wood naturally soaks up moisture.Wood models in fact grow and diminish a little throughout various seasons. This can be experienced by taking a trip 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 environment if possible. Positioning the design in a space with a dehumidifier for a number of days before covering the design may prevent the covering from sagging due to design shrinkage.

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

Bubbles and Imperfections:
Periodically the intense heat from the sun can cause bubbles and blemishes in the covering, specifically when using dark colors. To remove these, heat the bubbled location using a heat weapon to expand the air under the covering, causing the bubble to increase. Rapidly pop the bubble using a needle then wipe the location using a cold, wet wash cloth. The wet wash cloth quickly cools the location, permitting the covering to re-adhere. It may take a number of aim to totally remove the bubble/blemish, but this approach works great.

Clean Up:
The adhesive can be gotten rid of from the iron or design using acetone or a moderate thinner.
