Provides accelerated method for determining wear resistance of surface coatings and performance of cleaning compounds
Wet Abrasion Scrub Tester
• Tests coatings’ scrub and abrasion resistance and washability
• Provides precisely controlled conditions
• Yields repeatable, measurable results
Using two suspended brushes or sponges with a scrub rate of 37 cycles per minute (±1), the machine can be set for up to 100,000 strokes. Washing agent is precisely dosed via a peristaltic pump, free from cross-contamination by design. Stroke length is adjustable between 100 and 300 mm in 50 mm steps. Test items up to 1.5 cm thick can be clamped easily in the machine’s frame. Applications include testing for gloss retention or deterioration, soil or print removal and effectiveness of waxes or protectants. Material tested can include: paints, varnishes, inks and plastics; floor coverings, carpets and upholstery; glazed and unglazed ceramics; woods, leather, natural surfaces; metal including anodized or plated items. Unit is fan-cooled and includes a glass viewing panel. Includes two Nylon Bristle Brushes, two Rubber Mats and 2 Shims (12.7 x 0.25 mm).
Four Head Washability Tester (6411C10)
The four head tester adds these features to the wet abrasion tester above:
• Four heads enable four product tests at once
• Weights from 300 to 1,000 gm (in 100 gm increments) can be added to accelerate wear
• Motor speeds include 20, 25, 30, 35 and 37 strokes per minute
• Movable carriage enables test media direct application sponges
Optional automatic stroke counter has four large LCDs which indicate the number of strokes for each track. The tester allows the user to stop one or more counters while the others continue. Carriage lifts off for cleaning. Dimensions: 650 x 400 x 330 mm; weight 29 to 32 kg depending on configuration. For Scrub Media, see 6411C26 series.
