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 patented polymerizing process permanently fuses the color to the polyester film covering, eliminating the possibilities of color-layer separation and permits repositioning the covering on your model. UltraCote's unique ability to both shrink and stretch make it superior to other coverings for going around tight curves and wingtips.
Temp ranges are as follows:
Adhesion to wood begins at 200 to 220 degrees F.
Shrinkage onset begins at 300 degrees F.
Maximum shrinkage is at 350 degrees F.
When applying 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 meet or at the edge of the covering, it is 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 recommended, as it usually prevents the surface of the iron from scratching. The sock absorbs heat and will require the user to work slower or to turn the heat up 10%. Almost all professional builders use covering socks. Hangar 9 offers one of 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 actually grow and shrink slightly throughout different seasons. This can be experienced by traveling from the humid Midwest of the United State to the dry deserts of Las Vegas. After a few days in the desert, the model develops covering sags due to model shrinkage. It is recommend that you cover the model in a dry climate if possible. Placing the model in a room with a dehumidifier for several days before covering the model may prevent the covering from sagging due to model shrinkage.
UltraCote® will accept most types of polyurethane, epoxy, and automotive acrylic paints. It’s recommended that the surface be scuffed with 000 steel wool or Scotch® bright pads then thoroughly cleaned with acetone or thinner before painting. Model Dope or butyrate-based paint are not compatible with UltraCote®.
Bubbles and Blemishes:
Occasionally the intense heat from the sun can cause bubbles and blemishes in the covering, especially when using dark colors. To remove these, heat the bubbled area using a heat gun to expand the air under the covering, causing the bubble to rise. Quickly pop the bubble using a needle then wipe the area using a cold, wet wash cloth. The wet wash cloth rapidly cools the area, allowing the covering to re-adhere. It may take several tries to completely remove the bubble/blemish, but this method works great.
The adhesive can be removed from the iron or model using acetone or a mild thinner.
