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 use. A trademarked polymerizing process completely fuses the color to the polyester movie covering, getting rid of the possibilities of color-layer separation and permits rearranging the covering on your design. UltraCote's special ability to both shrink and stretch make it remarkable 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 start starts at 300 degrees F.
Maximum shrinkage is at 350 degrees F.

 



Surface area Preparation:
The covering job can only be as great as the surface of the surface area it's used over. In order for the covering to properly adhere to a surface, the surface area needs to initially|initially} be smooth and clean. Sand the design using 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 unpleasant bumps. Fill gaps and damages 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 prevent the filler from {showing|revealing} through.

Pro Suggestion - Some professional contractors “raise the grain” then sand a second time with 320 or 400 grit paper for the ultimate surface. After the design is sanded, utilize a moist fabric to clean down the design. Some modelers choose to utilize a fine-mist squirt bottle filled with water to dampen the surface areas to be covered. As the surface area dries, anchored wood fibers in the surface area will “stand up.” When dry, sand the surface areas 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 surface. Vacuum the design completely and prevent 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 couple of inches larger than needed to cover the wing. Eliminate the backing (conserve for later on) 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 Suggestion - If the iron you're using does not show the actual temperature, here is a pointer that will guarantee your iron is properly set.Water boils at 212°F. Enable your iron to warm up at a medium setting. When the iron reaches its supported temperature, carefully put a couple of drops of water on the iron's surface area. Change the temperature till the water just starts to boil off. This method is surprisingly precise and is normally within 10° (of the exact 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 shown (an iron sock is extremely 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 gently with the iron, allowing the heat (not pressure) to trigger 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 tracking edge and after that to the cutting edge as shown, using the iron at 220°F. If a wrinkle establishes, 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, gently sliding the iron (set at 220°) towards the tracking edge with the iron contacting 2 ribs. Utilizing your iron, adhere the covering to the staying ribs, working toward the tip and the root. Now complete the open structure leading edge, using the same method. If the leading edge is sheeted, then follow the technique listed above under “Covering a Solid-Sheeted Wing.”


Sealing the Edges:
With the iron set to 220°F, seal the leading and tracking edges. Utilizing a straight edge and a sharp #11 hobby knife, carefully trim the excess covering from the leading and tracking edge, allowing a minimum of a 1/4" overlap to twist around the leading and tracking edge of the wing. Now seal the leading and tracking edges firmly with the covering iron.


Wing Suggestion:
Depending upon the quantity of the curvature of the wing tip, high heat (as much as 350°F) may be needed to shrink and stretch the covering to remove all the wrinkles. Preset the iron to 300°F. Pull and stretch the covering around the wing tip while using heat with the iron. Keep in mind, UltraCote® can be carefully raised and repositioned to help remove wrinkles. This function is advantageous, especially when covering greatly curved wing tips. Continue working, pulling, and warming the covering around the tip till the covering is past the center of the tip. It may be necessary to increase the temperature of the iron to accomplish higher shrinkage to remove all wrinkles. Cut the excess covering using a #11 hobby knife, then reseal the covering on the wing tip.

Pro Suggestion - If sealing the covering in tight locations such as corners or fillets, using the Wall mount 9 ProTrim Sealing Tool is very valuable and results in an expert surface.


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 sure to cut a leading panel, making sure that the adhesive is on the appropriate side. Use the covering to the top of the wing using the same methods as explained in actions 3 through 6. Make sure 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, use heat using the same pattern utilized to use the covering starting at the spar and working outward. It may be necessary to increase the temperature to 320°F to get rid of persistent wrinkles. Use the minimum quantity of heat necessary to tighten the covering.

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


Covering Fuselages and Other Strong Surfaces:
The technique for covering fuselages and other basic flat surface areas is identical to covering a solid wing. Start with the bottom, then sides, and lastly the top. Initially, 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. Cut and seal the edges. About 1/4" or more overlap is suggested when using the next piece of covering. Diminish the covering, using the same method as explained above.

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

Multi-Temperature Control System:
Comprehending the benefits of this system and how to utilize it will make covering with UltraCote® easy and help to guarantee professional outcomes. When using UltraCote®, there are three essential temperature levels to be mindful of.

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

Pro Suggestion - Lots of professional contractors mark this temperature on their covering iron with a marker or striping tape for quick reference, as this temperature is utilized often whenever placing on covering.

Shrink On-Set Temperature-300°F (134°C)
At 300°F, UltraCote® starts 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 preliminary shrinking is done with the iron set at 300°F.
Maximum Shrinking Temperature-350°F (162°C)
At 350°F, UltraCote® reaches its maximum shrinking point. Raising the temperature above this point will not trigger additional shrinkage.

The rate of shrinkage is not straight in proportion to the temperature. The chart to the right shows how most of the shrinkage rate happens between 300°F and 330°F. At greater temperature levels UltraCote® continues to shrink but at a much slower rate. The smallest quantity of shrinkage happens between 340°F and 350°F. This is valuable to remember when shrinking and tightening up covering.


Important:Once UltraCote® is shrunk to a particular temperature, a higher temperature needs to be utilized to additional shrink the covering. For example, if the covering was shrunk using 320°F and wrinkles begin to appear/reappear, it will be necessary to utilize over 320°F to accomplish additional shrinkage.

Pro Suggestion - Always utilize the minimum heat necessary to get rid of wrinkles when tightening up the covering, therefore allowing plenty of shrinkage/temperature range staying if it's necessary to additional shrink the covering.



Valuable Tips

Multiple Colors:
When using covering with a second 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 essential to not overheat this area (over 300°F), as this will shrink and misshape the straight edge.

Use a Sealing Iron Sock:
A covering sock positioned over the iron is extremely suggested, as it normally prevents the surface area of the iron from scratching. The sock absorbs heat and will require the user to work slower or to turn the warm up 10%. Nearly all professional contractors utilize covering socks. Hangar 9™ offers among the best that features muslin on one side to prevent heat damage and soft cotton on the other side for a soft, scratch-free finish.

Dryer is Better:
Wood naturally absorbs moisture.Wood models in fact grow and shrink 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 couple of days in the desert, the design establishes covering droops due to design shrinkage. It is recommend that you cover the design in a dry environment if possible. Placing the design in a space with a dehumidifier for numerous days before covering the design may prevent the covering from drooping due to design shrinkage.

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

Bubbles and Acnes:
Periodically the intense heat from the sun can trigger bubbles and imperfections in the covering, especially when using dark colors. To get rid of these, heat the bubbled area using a heat weapon to expand the air under the covering, triggering the bubble to increase. Rapidly pop the bubble using a needle then clean the area using a cold, damp wash fabric. The damp wash fabric quickly cools the area, allowing the covering to re-adhere. It may take numerous tries to entirely get rid of the bubble/blemish, but this method works great.

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