Cross Hatch Cutting and Adhesion Tester
Category：Interior Material Tester
Introduction
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.
- 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.
- 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.
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.
