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
QDetermination of water-based interior-wall Coating adhesion, is this cross-cutting knife suitable?
A This model is suitable for the determination of water-based inner and outer wall Coating adhesion in architectural coatings. The cross-cut test is mainly carried out with knives, and the firmness of the Coating to the substrate is judged according to the number of squares of the film peeling. Use a sharp blade and a scale steel ruler to cut 11 cuts with a distance of 1mm in the vertical and horizontal directions of the test plate, and the vertical and horizontal cuts intersect into 100 squares. So it is applicable.
QIs this Cross Hatch Cutter ISO 2409 compliant?
A The Multi-Cross Hatch Cutter is suitable for ISO2409, please consult customer service for detailed application definition
QDo you have a video on how to use the adhesion scratching knife?
