Cross-Cut Tester Kit

Par­al­lel
Groove Adh­e­sion Test

This method is used for deter­min­ing the par­al­lel groove adh­e­sion of one or many coat­ing lay­ers on a sub­s­trate, gen­er­ally a metal panel. Cross-Cut Tester Kits are avai­l­able in 2 dif­fer­ent blade ver­sions, one is a multi-cut blade with 6 cutt­ing edges, the other ver­sion has one cutt­ing edge. The Cross-Cut Tester blades are made of har­d­ened steel alloy. The blades are designed for retain­ing a sharp cutt­ing edge and reduce the fre­quency of blade replace­ment.

ASTM method D3359 requires 11 cut lines:
1 mm cut­ter for films up to 50 µm (2 mils) thick
2 mm cut­ter for films between 125 µm (2 - 5 mils) thick

ISO stan­dards pre­scribe that the num­ber of cuts shall be 6, and that the cut in each direc­tion must be accord­ing to the film thick­ness and type of coat­ing used as shown below:
0 - 60 µm          1 mm space for hard sub­s­trates (metal)
0 - 60 µm          2 mm space for soft sub­s­trates (plas­tic)   
61 - 120 µm      2 mm space for hard or soft sub­s­trates
121 - 250 µm    3 mm space for hard or soft sub­s­trates

Comes com­plete with:
Cross-Cut Tester kit with blade
Hex wrench for chang­ing blades
Mag­ni­fier
Clean­ing brush
Plas­tic car­ry­ing case
Oper­at­ing instruc­tions
One roll of adh­e­sive tape in accor­dance with the stan­dard
