88 • WRAPS • 2 0 1 7 TOOLS & EQUIPMENT Worldwide – What is Cast? When I started traveling worldwide for workshops, I was really surprised to see installers who had no clue what cast film was. I was also introduced to more brands outside of the U.S. and Europe like Alltak in Brazil or Teckwrap in China. I even saw installers doing full wraps with films that would never even be consid- ered in the U.S. or Europe like Orafol 651, an intermediate calender cut vinyl film. The wrap companies and installers were not using these films because they liked the challenge (or pain). They use these films due to price point, availability, and, in some cases, lack of seeing the big picture. Teckwrap is a calendar film from China that has a lot of cool colors and the company brands itself well. However, an installer may not know that Teckwrap films have a much higher post-heating temperature. With Mactac Tuning film, also a calendar film, the post-heating temperature is 180 F while for Teckwrap films its 220F. This is because Teckwrap is a multi-layered film and thicker than standard colorchange calendar films. Not knowing this post-heating temperature can mean the difference between a happy client with a cool color/finish or a redo because of lifting. Alltak, a private manufacturer in Brazil, makes calendar full-print and colorchange film with a water-based adhesive that has air egress. One very successful direction they have taken is with textured films that have a medium to heavy sand-like grain (Jateado and Krusher correspondingly). For colorchange films, this texture creates a cool 3 D effect either subtle or dynamic. For full-print films, this texture means no solid overlaminate can be applied (this is not a problem because hardly any client in Brazil will pay for lamination). With flat-faced full-print films, no lamination means scratches and fading. Alltak's tex- ture actually helps minimize scratches and fading, which means their unlaminated wraps actually hold up well. Keep in mind that Teckwrap and Alltak, both polymeric calender films, have a 3-5 percent natu- ral shrinkage so be sure to wrap the film And the winner is: Great reaction from the winners of this year's Cambea #7 contest – install- ers in countries like Brazil have to learn how to wrap with unlaminated calender film, even on the curviest cars. Installers use films like Avery Dennison 800 for full-coverage wraps, but it's not made for two- or three-year colorchange wraps. With no lamination layer built in, the colors fade, the mate- rial breaks down and removals come off in pieces that leaves all the adhesive behind. 180F is the standard post-heating temperature installers know. For Teckwrap it's 220F. Not knowing this can mean the difference between an edge lifting or staying.
