I translate what is written in the info Tec of Piccole Ali:

PVC is one of the materials used in technological applications. It owes its versatility to the possibility of being mixed in various proportions to products plasticizers that make flexible and modeling. VQ models are clad in vinyl films Model pre-printed. The construction technique is also called "print-over-film. Unlike other manufacturers who adopt other ARF kits coatings based on polyesters, VQ Model employs a sturdy vinyl films on heat-sensitive adhesive (more like the film used to decorate the cars). The main motivation for this kind of choice comes from the type of livery kits VQ Model. Just look at the PC-6 Bird, P51 DAGORED the CAP10B ARF 60, the stick F-1500 and, in general, the camouflage paint schemes to note the complexity and richness of the same special graphs, such as: rivets , bolts, access doors, paneling lines, vintage look. To make the idea of the level of detail sufficient to consider that on some liveries the screw heads reproduced in the coating have different angles! VQ Model then chose the coating material according to the possibility of reproducing, complex and original liveries in the best manner possible and without the use (or with minimal use) of stickers and "decals." This type of graphic result is difficult to obtain (with the same qualitative result) with other types of coating. Another important motivation is linked to greater resistance of the coating mixture and the engine exhaust blast. The vinyl coating film thus has a number of advantages and disadvantages, like any other alternative technological solutions. The main strengths of the coated vinyl films are: - Possibility to make ARF kit with liveries graphically rich and complex and with the best level of detail - Major durabilit and resistance of the coating mixture and by discharges from internal combustion engines Increased torsional stiffness of open structures coated The main disadvantages are: - Covering heavier than some polyester film (specific gravity similar to that of solid MonokoteTM) - Increased sensitivity to heat Increased sensitivity to heat the vinyl film takes a few tricks to allow for acclimatization to the same temperature. During the hottest periods of the year, the exposure of the coating to the outside temperature or strong sunlight can induce relaxation of the film. As the coating is "acclimatizes" (ie, the temperature rises and the coating becomes uniform) the same tender to retire within 3-5 minutes removing the wrinkles induced by first exposure to heat. In these particular circumstances, may be sufficient to bring the model in a shaded area to quickly eliminate the "wrinkles" above. VQ different models (such as: the FW-190 ARF 60, the P-40 ARF 60, the Ki61 ARF 60, etc.) have the structures of the fuselage, wing and tail stabilizers fully lined with balsa. In this case, the vinyl coating being completely bound to balsa tends not to suffer the phenomenon of wrinkling when exposed to heat. RECOMMENDATIONS 1) The coating is applied at the factory with the utmost prudence to avoid the formation of wrinkles. However, due to changes in temperature and humidity of the coating may show wrinkles (just as can happen for the other covering materials) at the open facilities. To eliminate these wrinkles is enough hot air to inflate with a normal hairdryer initially set a low temperature. At first, the film will relax forming wrinkles. After blowing the hot air the film will begin to retire Eliminado wrinkles. If necessary, you should increase the temperature of hot air and / or repeat the cycle until you get the desired result. 2) DO NOT USE THE IRON OR HOBBY, USE ONLY THE FON. 3) In the hottest days and more sunlight, allow the acclimatization of the film to external conditions. At first, the film forming tender to relax wrinkles. Later, after a few minutes, the film itself inizier retire automatically eliminating wrinkles. The process can be accelerated by bringing the model in the shade. 4) To clean the excess glue during assembly not use alcohol or thinners pure pure (like acetone). Use a product for cleaning glass or alcohol dliluito to 60% max. You may want to try in the corner. 5) Do not clean the coating using the card as it has the same abrasive effect (on all covering materials). Use a soft cloth. 6) To clean the waste mixture and / or residues of combustion engine exhaust products used for cleaning the glass or alcohol at 60% max. Do not use pure alcohol or pure solvents. REPAIRS Minor repairs for minor repairs you can use scraps of film eventualmenti present in the packaging of the kit. Alternatively, you can also use strips of adhesive shrink film commercially available. Major Repairs For repairs that involve large areas can have, on order, with the color of the sheets of model specific. For further information write to: [email protected]
