A solution that really hits the mark

The flaws might be small, but covering them up is a big job! That’s a fact of life
for anyone who’s ever performed professional spot touch-up work on paintwork flaws. Depending on the extent of the faults, dabbing, drying, rubbing down and polishing tiny spots can take an exceptionally long time. Up till now that is, because adphos has developed the NIR MICROSPOT REPAIR system which reduces the drying and curing process from 15–30 minutes to 20–50 seconds.n.

NIR (Near Infrared) wavelengths are shorter than any other form of infrared radiation
and generate the highest energy output. NIR penetrates most materials extraordinarily fast
and heats them up extremely rapidly. Precisely targeted NIR radiation generates the
required process temperature in a very short space of time.

Simple and compact
In car manufacture, small flaws in the top coat are often repaired using paint spots. These are applied to the pre-buffed flawed area with a dabbing tool, then either dried for 15 –30 minutes with IR stand-type dryers at a spot repair station or returned to the top coat dryer.With the NIR MICROSPOT REPAIR system —a simple, compact hand-held device—the drying and curing process can now be reduced from 15 – 30 minutes to just 20 – 50 seconds. Precisely targeted, controlled NIR radiation dries and cures the surface of the paintwork in the radiation area with a defined temperature profile, and does so with such speed that the paint spot is then immediately ready for rubbing down and polishing. The following systems are available for this purpose, depending on your requirements: NIR MICROSPOT REPAIR for small top-coat flaws on steel and SMC. NIR MICROSPOT REPAIR Plus for small top-coat flaws on steel, SMC and aluminum. NIR MICROSPOT REPAIR PP Plus for small top-coat flaws on steel, SMC, aluminum and plastics.

Fast and precise

A whole range of uses
adphos consulted system users throughout the development of NIR MICROSPOT REPAIR. We worked together with a car manufacturer to investigate the thermal procedure during the dabbing process, develop the system to series production stage and launch it worldwide. NIR MICROSPOT REPAIR repairs dimples and pinholes, wetting defects, larger occlusions that cannot be polished, scratches and stone impacts in the top coat on steel, aluminum, SMC, PP and other plastics.

1. The device is lined up above the spot that has been dabbed with paint. Non-slip, silicon free spacers ensure exact positioning.
2. Within the radiation area, which has a diameter of 35 mm, the paint spot is dried in around 20 – 50 seconds using high-energy NIR radiation.
3. The next dabbed spot can then be treated, or the rubbing down and polishing process can be initiated immediately.

Ideal for drying and curing with NIR MICROSPOT REPAIR:series clear coating systems (single-component, dual-component). Special dual-component clear coatings for scratch-resistant surfaces ,Dual-component repair coatings ,Water-based top coats (single-component, dual-component) ,Solvent-based top coats (single-component, dual-component) High solid coatings. The NIR treatment causes no damage either to the coating surface or the substrate because the maximum temperature reached during this controlled process is below the temperature at which damage can occur.

From the manufacturer to the coating plant

A large range of applications
NIR MICROSPOT REPAIR can be used to perform repairs on the production line and in spot painting booths, assembly areas, dispatch areas, processing centers, car manufacturing branches, car workshops and paint shops. The system removes tiny paintwork flaws cost effectively and brings an extremely fast return on investment. In the spot booths of car manufacturers, for example, process costs at full capacity are reduced by up to 90 % and material consumption up to as much as 98 % compared with spot/partial painting. Integrating the repair technology into the series production workflow significantly increases capacity in the spot/partial painting booths and on the production line. Because vehicle bodies do not need to be fed back into the coating or drying processes, productivity is not impaired. NIR MICROSPOT REPAIR also provides the perfect conditions for processing stationary vehicle bodies at team workstations. What’s more, the fact that the system is extremely user-friendly means it can also be used fast and flexibly on vehicles in the repainting and assembly stages.
