SPAP (Symach Paint Application Process) represents the proper painting method that integrates the use of both Drytronic technology and the robot.

Since it dries the paint in just a few seconds, the Drytronic technology enabled us to develop a painting process that significantly reduces flash-off times, as the robot performs the process even faster.

Drytronic drying quality is superior to any other drying process involving the use of hot air ovens or electric infrared heaters, because reticulation is instantaneous and 100% complete. The painting product is chemically stable and inert. This prevents the appearance of any future defects, while at the same time allowing for immediate sanding and polishing. The SAP application and drying process – is ideal for all painted products and for any brand name, even using different drying formulas, all while fully complying with the indications provided on the manufacturer’s technical data sheet. The time required to apply the paint to the products is reduced by 60% to 70%, while drying time is reduced by 80% to 90% with respect to any conventional system.

Preparation: SPAP Process for Bodyfiller

This application and drying process allows for filling operations to be completed with a single application, offering superior compactness and quality with respect to the application of two coats using the traditional cycle, in less than half the time. For example, the continuous and uninterrupted filler application and drying takes place in less than five minutes.

SPAP SYSTEM

Example of a job of 2 panels

The filler is applied to the surface to be repaired with a thin and compact initial layer. The time required for applying the filler is about 01:00 minute.


CONVENTIONAL SYSTEM

Example of a job of 2 panels

Application of the filler to the sheet metal in a thickness greater than necessary.The time required for applying the filler is about 4:00 minutes.


Drying is immediately performed by the robot upon completing the application of the filler, at a speed of approx. 80 linear cm per minute. The time required for drying with the robot is about 02:00 minutes


Drying is performed at ambient temperature over the course of 30 to 40 minutes, or else by using an electric IR lamp. The time required for drying with an electric IR lamp is about 16:00 minutes (2 positioning, 8:00 minutes each one).


The application of the filler is completed while the dried surface is still warm, without sanding. The time required for applying the filler is about 02:00 minutes


The first sanding operations do not provide for optimal surface results due to the porosity and the residual undulation of the surface itself. These are caused by the rough modelling of the high thickness application, which does not allow for precise work to be carried out. The time required for sanding is about 30:00 minutes.


Drying is immediately performed by the robot upon completing the final application of the filler, at a speed of approx. 60 linear cm per minute. The time required for drying is about 03:00 minutes.


The second filler application stage involves the application of a thinner coat of filler in order to eliminate any porosity and undulation. The time required for applying the filler is about 2:00 minutes.


Sanding operations are simplified thanks to the excellent drying quality and the complete absence of porosity. The time required for sanding is about 20:00 minutes


Drying is performed at ambient temperature over the course of 30 to 40 minutes, or else by using an electric IR lamp. The time required for drying with an electric IR lamp is about 16:00 minutes (2 positioning, 8:00 minutes each one).



The time required for sanding is about 16:00 minutes


The total time required for carrying out the entire filler application cycle on two panels using SPAP system is about 28:00 minutes.


The total time required for the entire filler repair cycle using the conventional system is about 84:00 minutes.

Preparation: SPAP Process for Primer

The undercoat application process is carried out without interruption, because the flash-off between coats is performed by the robot. For example, the application and drying of three coats of Undercoat can be performed in less than eight minutes. Drytronic technology even allows for the Undercoat to be applied using a roller, in thicknesses and with application and drying times identical to that of spray applications, but with a 60% savings in paint product and a 100% savings in terms of masking times and materials.

Paint: SPAP Process for Water Base

Depending on the brand, the application of the two or three coats takes place consecutively and without interruption. For example, less than six minutes are required for application and drying of three painted panels.

SPAP SYSTEM

Example of a job of 3 panels

With the SPAP system, the water base is applied in three consecutive coats: 1) Spraying the initial coat; 2) Spraying the full coat (complete coverage); 3) Spraying the shaded coat. The applications take place consecutively, with no need to wait for flash-off times in between. The time required for water base spraying is about 3:00 minutes. The indications above refer to the application of the base with drop coat on wet surface. If applying the drop coat over a dry surface, the work time is extended by about 5 minutes.
