Detailed Instructions

striping tape for quick reference, as this temperature is used frequently 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
attached using an iron set to 220°F, the next step is to shrink the covering. This initial shrinking is done
with the iron set at 300°F.
Maximum Shrinkage Temperature-350°F (162°C)
At 350°F, UltraCote® reaches its maximum shrinking point. Raising the temperature above this point
will not cause further shrinkage.
The rate of shrinkage is not directly in proportion to the
temperature. The chart to the right shows how the
majority of the shrinkage rate occurs between 300°F
and 330°F. At higher temperatures UltraCote®
continues to shrink but at a much slower rate. The
smallest amount of shrinkage occurs between 340°F
and 350°F. This is helpful to remember when shrinking
and tightening covering.
Important:
Once UltraCote® is shrunk to a specific temperature, a higher temperature must
be used to further shrink the covering. For example, if the covering was shrunk using 320°F and
wrinkles begin to appear/reappear, it will be necessary to use over 320°F to achieve further
shrinkage.
Pro Tip - Always use the minimum heat necessary to remove wrinkles when tightening the covering,
thus allowing plenty of shrinkage/temperature range remaining if it's necessary to further shrink the
covering.
Helpful Hints
Multiple Colors:
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.
