Cross Hatch Adhesion Tester &Cross-Cut Tester Kit According to ISO2409-1992 standard design and manufacture. Applicable to GB / T9286-98, BS 3900 E6 / ASTM D3359. Uses: The instrument is mainly suitable for organic coating adhesion assay Hatch. Applies not only to the laboratory, the construction site can also be used under various conditions. Working principle and scope The instrument is a certain specification tool that will make the coating lattice graphics cut andpenetrate, Hatch completed by six graphic classification, assess the effect of the coating adhesion separated from the substrate. Technical instructions 1, multi-blade cutter spacing are: 1 + 0.01mm, 2 + 0.01mm. 2, multi-blade cutter addendum straightness were: ?0.003mm?0.006mm. 3, multi-blade cutter working tooth tip width: ?0.05mm. Operation and Use 1, the specimen must be prepared according to ISOR1514 and ISO2828 requirements. 2, the test piece is placed on the tablet hardness sufficient. 3, handheld Hatch handle, so multi-blade cutter perpendicular to the specimen plane. 4, with uniform pressure, steady approach does not vibrate and 20-50mm / S cutting speed cutting program. 5, the specimen is rotated 90 degrees on the cutting stroke cuts repeat the above operation, so as to form a lattice graphics. 6, with a soft bristle brush on both sides of the diagonal lattice pattern gently back 5 times, 5 timesforward brush specimens. 7, the test at least at three different locations on the test piece is completed, if the test results of three different positions, the experiment should be repeated at more than three positions, all whilerecording the results. 8. To replace the multi-blade cutter, use a screwdriver blade Loosen the two screws, put the knives, knifeblade attached to the handle side of the site, and tighten the screws. Precautions 1. All cuts should be through the coating, but not too deep cut substrates. 2, as a result of the coating is too thick and hard and can not penetrate the material in the end, theexperiment is not valid, but it should be stated in the test report. 3, the test must be a US company 3M tape produced 610-1PK special tape test. The tape posted on the wholecross-hatch, and then tore off the minimum angle, the result may be in proportion to the gum off the areadetermined according to the film surface. 4, the test should be carried out at a temperature of 23 ± 2 °C and relative humidity of 50 ± 5%.
