Cross Cut Adhesion Test

The TQC Cross Cut Adhesion Test KIT (CC1000) is used to test the adhesion of dry coats of paint on their substrate by means of a series of cuts through the coating. Two series of parallel cuts cross angled to each other to obtain a pattern of 25 or 100 similar squares. The ruled area is evaluated by using a table chart after a short treatment with a stiff brush, or adhesive tape for hard substrates.

Description

Product Description

Features :

•Self-adjusting knife-holder ensures equal pressure on the cutting knife

•Round cutting knife with eight cutting edges for longer lifetime

•Ergonomically shaped handle

•Easy to change round cutting knife

•Wide range of knife sizes available for different coating thicknesses and substrates and according to different standards

 

USE

• Make two cuts/scratch, perpendicular to each other, drawing the handle with the appropriate cutter (depending on coating thickness and substrate) through the coating into the substrate thus making the lattice pattern.

 • Brush the pattern lightly with the supplied brush several times back and forth along each of the diagonal lines of the lattice pattern.

 • For hard substrates only the test can be extended by applying the adhesive tape parallel to one set of cuts over the lattice pattern and pull it off steadily in 0.5 to 1 sec. at a 60° angle within 5 minutes after applying acc. to ISO. Acc. to ASTM within 90s (±30s) at a 180° angle.

• Carefully examine the cut area, if required using the magnifier and classify the test

 

SPECIAL CARE

• Clean with a soft and dry cloth. Do not use water or solvents.

 • Avoid mechanical shocks or contact with sharp objects

 • Always use high quality alkaline batteries. (Illuminated magnifier)

 

SAFETY PRECAUTIONS

• A knife is a sharp object. Be careful when using it.
