![]() ![]() Cleaning the instrument won’t be an obstacle either: A drip pan and paper holder are part of the standard supply.įor more information about the TQC Automatic Film Applicator ‘Compact’, contact the TQC headquarters in The Netherlands. The price level of the AFA Compact should be no obstacle for any lab to start producing reproducible and accurate draw downs. This results in a very intuitive operating system which is enhanced with information on the machine’s display. At each step of the operating menu the interface detects which buttons are active and indicates these by means of an illuminated red centre. This unique system guides the operator through the interface of TQC lab-machines. Different paint types (oil, water) and substrates (metal, wood, fiberglass) are replicated by using different types of drawdown cards. Operating is easy through the standard TQC operating interface with Triple i technology. By measuring reflectance values of both parts of the card one can gain a quantitative opacity value of a paint sample. The thickness of this film is directly related and. Black and white cards are used to measure both opacity and contrast ratio. Moving the drawdown bar at a constant velocity causes the paint to be spread over the card, in a thick film. The AFA Compact is available with a glass – or perforated vacuum bed. Drawdown cards are used for testing paints and coatings through wet film preparation. Laboratory Drawdown Rods (N008-026, N008-026A) are designed for users producing test samples up to 8½' wide. The AFA Compact is suitable for both wire wound rod applicators and block applicators. For further explanation please follow the link below. To sum up: Request draw downs from your painter whenever you are getting a colour match done. These lines are created by draw down bars that are strictly calibrated using different gauges of wire to tightly control the thickness of the coating being applied to a metal panel. ![]() Application speed can be set from 1 to 150 mm/s. The small parallel lines visible on some lab prepared panels are known as draw-down lines. ![]() This entry level film applicator accepts charts up to A4 size. Especially the speed of application is determinative for the final thickness of the draw down.įor those laboratories that are still applying paint films manually the TQC Automatic Film Applicator ‘Compact’ has been developed. A manual draw down is affected by many variables such as application speed, applied force on the applicator block/barcoater and above all the operator. A reproducible film is crucial to run meaningful tests in a paint laboratory. ![]()
