Hangar 9 UltraCote 10 Meter, Orange

Summary

 



Surface area Preparation:
The covering job can just be as excellent as the surface of the surface it's applied over. In order for the covering to effectively comply with a surface, the surface should {first|initially} be smooth and clean. Sand the design using a sanding block and progressively 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 unattractive bumps. Fill spaces and damages with a premium 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 Idea - Some expert home builders “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 damp 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 dries, inserted wood fibers in the surface will “stand.” 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 under the covering, producing a bumpy surface. Vacuum the design completely and prevent touching the design with oily hands.Your design is now {ready|prepared|all set} for covering!



Trim Film to Size:
Start by covering the bottom of one wing half. Using scissors or sharp pastime knife, cut a piece of UltraCote® a couple of inches bigger than needed to cover the wing. Get rid of the support (save for later) 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 using does not show the actual temperature, here is a tip that will guarantee your iron is effectively set.Water boils at 212°F. Allow your iron to warm up at a medium setting. When the iron reaches its supported temperature, thoroughly put a couple of drops of water on the iron's surface. Change the temperature up until the water simply begins to boil off. This approach is surprisingly accurate and is usually within 10° (of the specific application temperature of 220).


Adding Covering to Spar:
Tack the covering to the spar or the peak of the wing, using your iron as shown (an iron sock is highly recommened). Gently pull the covering towards the root and towards 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, permitting the heat (not pressure) to activate the adhesive and bond the covering to the peak. Ideally, the covering will naturally lay flat versus 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 outside to the routing edge then to the leading 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 towards the routing edge, carefully sliding the iron (set at 220°) towards the routing edge with the iron calling 2 ribs. Using your iron, adhere the covering to the remaining ribs, pursuing the idea and the root. Now complete the open structure leading edge, using the very same approach. If the leading edge is sheeted, then follow the method noted above under “Covering a Solid-Sheeted Wing.”


Sealing the Edges:
With the iron set to 220°F, seal the leading and routing edges. Using a straight edge and a sharp #11 pastime knife, thoroughly trim the excess covering from the leading and routing edge, permitting a minimum of a 1/4" overlap to wrap around the leading and routing edge of the wing. Now seal the leading and routing edges safely with the covering iron.


Wing Idea:
Depending upon the quantity of the curvature of the wing idea, high heat (up to 350°F) might be needed to shrink 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 idea while using heat with the iron. Keep in mind, UltraCote® can be thoroughly raised and repositioned to assist get rid of wrinkles. This feature is helpful, particularly when covering sharply curved wing suggestions. Continue working, pulling, and heating the covering around the idea up until the covering is past the center of the idea. It might be essential to increase the temperature of the iron to achieve greater shrinkage to get rid of all wrinkles. Cut the excess covering using a #11 pastime 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 extremely helpful and results in an expert 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. Make sure to cut a leading panel, making sure that the adhesive is on the right side. Use the covering to the top of the wing using the very same techniques as described in steps 3 through 6. Make sure 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 shrink the covering. With the iron set to 300°F, apply heat using the very same pattern used to apply the covering starting at the spar and working outside. It might be essential to increase the temperature to 320°F to obtain rid of persistent wrinkles. Use the minimum quantity of heat essential to tighten the covering.

Pro Idea - Usage heat, not pressure, to shrink 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 likewise be used to shrink the covering. This works particularly well over an open structure. It can likewise 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 applied.


Covering Fuselages and Other Strong Surface areas:
The method for covering fuselages and other simple flat surface areas is identical to covering a solid wing. Start with the bottom, then sides, and lastly the top. First, 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 suggested when using the next piece of covering. Shrink the covering, using the very same approach as described above.

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

Multi-Temperature Control System:
Comprehending the advantages of this system and ways to utilize it will make covering with UltraCote® simple and help to ensure expert outcomes. When using UltraCote®, there are three crucial temperatures to be mindful of.

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

Pro Idea - Lots of expert home builders mark this temperature on their covering iron with a marker or striping tape for quick reference, as this temperature is used regularly whenever putting 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 Shrinking Temperature-350°F (162°C)
At 350°F, UltraCote® reaches its maximum shrinking point. Raising the temperature above this point will not cause additional shrinkage.

The rate of shrinkage is not directly in proportion to the temperature. The chart to the right demonstrates how most of the shrinkage rate happens between 300°F and 330°F. At higher temperatures UltraCote® continues to shrink however at a much slower rate. The smallest quantity of shrinkage happens between 340°F and 350°F. This is helpful to remember when shrinking and tightening up covering.


Crucial:As Soon As UltraCote® is shrunk to a specific temperature, a higher temperature should be used to additional shrink the covering. For instance, if the covering was shrunk using 320°F and wrinkles start to appear/reappear, it will be essential to utilize over 320°F to achieve additional shrinkage.

Pro Idea - Always utilize the minimum heat essential to get rid of wrinkles when tightening up the covering, hence permitting a lot of shrinkage/temperature variety remaining if it's essential to additional shrink the covering.



Practical Tips

Several 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 satisfy or at the edge of the covering, it is essential to not overheat this location (over 300°F), as this will shrink and misshape the straight edge.

Use a Sealing Iron Sock:
A covering sock put over the iron is highly suggested, as it normally 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%. Almost all expert home builders utilize covering socks. Hangar 9™ offers among the very 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 Better:
Wood naturally soaks up moisture.Wood designs really grow and shrink slightly throughout different seasons. This can be experienced by traveling 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 develops covering droops due to design shrinkage. It is recommend that you cover the design in a dry climate if possible. Placing the design in a room with a dehumidifier for several days before covering the design might prevent the covering from sagging due to design shrinkage.

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

Bubbles and Acnes:
Sometimes the extreme heat from the sun can cause bubbles and imperfections in the covering, particularly when using dark colors. To get rid of these, heat the bubbled location using a heat gun to broaden the air under the covering, causing the bubble to rise. Quickly pop the bubble using a needle then clean the location using a cold, wet wash fabric. The wet wash fabric rapidly cools the location, permitting the covering to re-adhere. It might take several attempt to entirely get rid of the bubble/blemish, however this approach works great.

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