Cross Hatch Cutting and Adhesion Tester T110

The Cross Hatch Cutting and Adhesion Testing provides a relative movement of  the scratch head to the surface of the material, and finally evaluates the  sensory level of the scratch after scratching, the chromatic aberration of the  scratched area and the unscratched area, or peeling condition of the surface  coating of the sample after being scraped and adhered by tape, which is a common  test instrument for evaluating the scratch resistance of the surface of the  material and the coating. The good repeatability of the experimental data can  help the manufacturer to effectively control the production and verify the  performance of the product.

1. The LCD screen is used to control and display the test process. The test  grid number, length, and speed can be freely set according to user' s  requirements. Unique sample holder enables the sample clamping is firm and easy  to use.

2. The equipment adopts the stepping motor of high quality, and adopts the  guide rail structure transmission in the horizontal and vertical directions.  With characteristics of small gap, uniform movement, lower noise, higher test  precision, good repeatability and long service life.

Application

It is suitable for testing automotive interior materials, plastics, rubber,  leather, coated fabrics, coating materials, composite materials, paints, inks,  soft metals and other industries. It is widely used in product quality control,  new product development performance verification, testing mechanism testing and  other fields.

It is applicable to the performance verification of new products, quality  control of the production department, and the of material properties for the  third-party testing organization, the product performance verification  laboratory, and the quality and technical supervisiondepartment, etc.

Features

Interchangeable multi-range weights

The instrument has a wide load range and can meet different standard tests.  And also, the different pressurization loads can be customized according to  customer' s requirements.

Simple and reliable sample fixation

The spinning type fixed sample enables that the sample is easy to install and  not easy to slide, the replacement type stationary fixture is replaced according  to the type and size of the friction head to meet a certain friction area.

Smart touch screen operation

The touch screen operation interface is simple and easy to use, and can be  selected in both Chinese and English. It is convenient to select the stroke,  speed, and scraping grid number, and can achievedifferent pressure tests at the  same time.

Rail positioning

The device adopts guide rail transmission with high precision, low noise and  long service life.

Multiple test suites

The flexible fixture can be interchanged with the imported friction head to  meet different standards and different test requirements.

Test Procedure

1. First, prepare the accessories and test samples.

2. Place the test sample into the fixture and tighten securely. Attach the  scraper head to the bottom of the guide rod and tighten securely. Attach the  weight to the top of the guide rod and tighten securely.

3. Turn on the power switch to enter the LCD operation interface. Set  parameters such as speed, grid count, spacing, and stroke.

4. The guide rail drives the scratching head to perform a scraping motion  against the material surface. When the set value is reached, the second-stage  dialog box automatically pops up.

5. Remove the screws on both sides, rotate the test fixture horizontally by  90 degrees, and reconfigure parameters such as speed, number of passes, spacing,  and stroke.

6. The scratching head performs a scraping motion against the material  surface. It automatically stops upon reaching the set value. Remove the sample  for observation.

7. Shut down the instrument to end the test. Remove the sample for analysis  and comparison. Evaluate the visual grade of post-scratch marks, color  difference changes between scratched and un-scratched areas, or coating peeling  after tape adhesion treatment on the sample surface.

FAQ

1.What is the cross hatch test for adhesion?

This basic and very subjective test method involves the user cutting an “X”  through the coating, down to the substrate, using a sharp utility knife. The  blade of the knife is then used to determine how easily the coating lifts off  the substrate at the intersection point of the cut.

2.What is the ISO standard for cross hatch adhesion test?

Cross Hatch Adhesion testing is a proven technique for estimating the  adhesion of coatings, including painted surfaces. This method, which is carried  out in accordance with DIN EN ISO 2409, is explicitly not used to measure the  adhesive strength, but rather to estimate it.

3.What is the ISO 4624 adhesion test?

ISO 4624:2016 specifies three methods (i.e. one dolly or two dollies on a  painted panel and two dollies, one as painted substrate) for determining the  adhesion by carrying out a pull-off test on a single coating or a multi-coat  system of paint, varnish or related product.

4.What is the purpose of an adhesion test?

An adhesion test measures the force required to separate two surfaces that  have been brought into contact under controlled conditions. It quantifies a  product's adhesive strength, tack, and cohesiveness, helping manufacturers  understand how strongly a product sticks to another surface or itself.

5.What is the ISO standard for adhesion test?

ISO 4624 – It is the standard for the pull-off test for paint and varnish  adhesion. ASTM D2197 – It is the standard for the scrape test for testing the  adhesion of organic coatings. ASTM D6677 – It is the standard for the knife test  for testing adhesion.
