Descrição

The TQC Scrub Abrasion and Washability Tester is used to test the resistance of paint, varnish or coatings to scratching, wearing, and color loss due to wet or dry abrasion, by simulating everyday wear from cleaning actions or general use. The test is either used as a “pass or fail” test by testing to a specified number of strokes or defining the minimum number of strokes at which a coating fails by checking at regular intervals. The TQC Scrub Abrasion and Washability Tester is suitable for a wide range of scrub, abrasion and washability tests that are in use. FEATURES

Preset range option.
Easy intuitive operating interface with Triple i Control (Intelligent Illumination Interface).
Full color display.
Easy to update software.
Manual movement.
Compatible with a large range of accessories.

INSTRUMENT CONTROLS AND FUNCTIONS

Flexible adaptation to many tests

The TQC Scrub Abrasion and Washability Tester allows for the most flexible adaptation of the wide range of scrub, abrasion and washability tests that are in use. First the base apparatus has to be selected from two models. The TQC Scrub Abrasion and Washability Tester - Basic (Art. Nr. AB6010) without pumps for dry tests, and the TQC Scrub Abrasion and Washability Tester - Standard (Art. Nr. AB6000) with pumps for dry and wet tests. Each base unit is completely flexible and allows for easy exchange of the tools used for testing. A variety of tests are possible, with just small modifications to make the device suitable for other tests. This modular system significantly decreases the costs for laboratories to comply to many standards. To select the right parts, we refer to the custom Ordering Matrix and the Standard Configuration Table.

Case Study

Customer - Confidential (Yachtbuilder)
Question - Test and quantify the wear on yachtcoatings caused by fendermaterial.
Apparatus - AB6000 TQC Scrub Abrasion and Washability Tester AB5020 Universal Material Holder Tool + additional weights
Procedure - Yachtbuilder was experiencing customers claims about marks and wear in the topcoat of their yachts located at the positions of the fenders. It was suspected that either the fender material or the plasticizers in the fender material was somehow aggressive to the yacht’s topcoat.
- Two different trays were used to perform two tests simultaneously (wet and dry) .
- Test panels, coated with the proper topcoat were positioned at the bottom of the scrub tester.
- The tools holders were each equipped with the fender material and an additional weight of 1000 gram.
- One test was performed dry.
- One test was performed with dosing sea (salt) water at rate of 0.2ml/min .
- Stroke length was set at 300mm.
- Stroke speed was set at 30 strokes per minute.
Result - Clear signs of wear are observed after 2000 strokes with both the wet and dry test. It was shown that the wet test showed more severe results than the dry test. Multiple tests showed that the AB5020 provides reproducible results and therefore it has been proven the TQC scrub test performs well as system to test and quantify the wear resistance of yachtpaints.
