Multivariate Cross Hatch Cutter

Introduction

TQC CC1000 series multi-element cross-cutters include five models: VF1839, VF1842, VF1844, VF1846, and VF1847, corresponding to different coating film thicknesses. The CC1000 series scratcher has an automatically adjustable blade holder, which ensures a balanced pressure on the blade. This round cutter has eight cuts.

Product acessories

The tool box for the TQC CC1000 series multi-element grating Tester contains: a soft and easy-to-grip handle, a hard cutting blade (the blade is replaceable, see above), a nylon brush, an illuminated magnifying glass, and tape.

Principle

TQC CC1000 series multi-element cross-hatch device uses the Principle of the cross-hatch method. The cross-hatch method is a test method for measuring the adhesion of dry coating on the surface. It uses a row of 6/11 blades between two outer conductors. Mark out 25/100 squares and determine the evaluation level through comparison. Measures the adhesion of a dry coat of paint to a substrate through a series of cuts. Cut out two parallel lines that cross at right angles to get 25 or 100 squares. Assess the area where the parallel lines intersect on a table and treat it briefly with a stiff brush or with tape on a hard substrate.

FAQ

[Q]

Is the soft copper foil with a thickness of less than 1mm a soft substrate? Can the VF1842 film scratching knife be tested?

[A]

Hello, yes, it belongs to flexible substrate. This model of TQC VF1842 can test soft substrate with 0~ 60 micron Film thickness.

[Q]

Are All Multivariate Cross Hatch Cutters Available for Detection in the ASTMD3359 Standard?

[A]

Not necessarily, but this VF1842 Multivariate Cross Hatch Cutter can be considered.

[Q]

Coated steel adhesion measurement, need to develop 2mm spacing cutter teeth, is it referring to this one?

[A]

This one meets your selection requirements. The following is the technical paper written by Fu Lei "Test Technology of Coated steel" for your reference: Coated steel coating is suitable for evaluating the adhesion of the substrate or the ability to resist separation between coats in a multi-layer coating system. It is on the coating surface of the sample, cut out the checkerboard grid pattern with six or eleven cuts in each direction with a cutter, and cut all the way to the substrate, stick the scotch tape on the grid, and then tear it off. The adhesion of the coating is evaluated by the peeling face of the coating. The scotch tape is required to be 25mm wide and the bond strength is (11 ± 1) N/25mm wide. The coating is not more than 50μm, the 11-edge, 1mm-spaced scribe is selected, the coating is between 50μm-125μm, the 6-edge, 2mm-spaced scribe is selected, and then the surface of the sample is 60 °. The force in the direction of the angle quickly pulls down the tape, and tests are carried out on 3 different parts of the sample. The worst evaluation grade is reported, which is divided into 6 grades, divided into 6 grades by the size of the peeling coating area (0, 5%, 15%, 35%, 65%).
