Adhesion Testing / Adhesives Testing

Adhesion is the bond strength measurement of a coating to a substrate. When an adhesive is bonded to an item or surface numerous physical, mechanical and chemical forces come into play, which may have an effect on each other. These need to be tested before a product can be used.

Typical test measurements include

²  180 degree and 90 degree peel tests

²  Lap shear tests for evaluating the shear strength of adhesives for bonding two surfaces together and welds such as metal and plastic welds

²  Tensile strength

²  Seal strength, peel strength and adhesion strength tests to determine adhesion strength of flexible plastic packaging

²  and so on

Some of adhesive standards developed by ASTM

²  D1002 - 10 Standard Test Method for Apparent Shear Strength of Single-Lap-Joint Adhesively Bonded Metal Specimens by Tension Loading (Metal-to-Metal)

²  D2095 - 96(2008) Standard Test Method for Tensile Strength of Adhesives by Means of Bar and Rod Specimens

²  D3165 - 07 Standard Test Method for Strength Properties of Adhesives in Shear by Tension Loading of Single-Lap-Joint Laminated Assemblies

²  D2339 - 98(2011)Standard Test Method for Strength Properties of Adhesives in Two-Ply Wood Construction in Shear by Tension Loading

²  and so on, please refer to http://www.astm.org/Standards/adhesive-standards.html

Adhesion testing can be carried out on a range force and material testing systems which will depend on your application needs, force capacity, and the data you require from your test results. We have a wide variety of force gages, motorized force test stands, and material testing systems and software to meet your application needs.

u  NLW-20 Adhesive Tensile & Shear Tester

This Instrument is professionally applicable to the determination of tensile, shearing, and pulling properties of various adhesives, which conforms to various ASTM standards ASTM D1002, ASTM D2095, ASTM D3165, and ASTM D2339.

u  CZY-G Initial Adhesive Tester

This instrument is used to test the initial adhesion property of adhesive tapes. It is based on falling ball method and the initial adhesion property of adhesive taps could be obtained by observing adhesive effect occurred immediately after rolling ball and adhesive specimen come into contact.

This Instrument conforms to JIS Z0237.

u  CZY-6S Adhesive tapes retention adhesive tester

This Instrument is used to measure the retention adhesion properties of adhesive tapes in a relative long time. The test plate with adhesive specimen is vertically hanged on the stand and its bottom is attached with a standard weight. The retention adhesive property could be obtained by measuring the displacement of specimen on vertical test plate or the time to failure at such load.

The Instrument has 6 work stations, which highly improved the efficiency of the testing. It is controlled by computer and timing is automatic finished.

u  There is another instrument can be used to test the tensile strength and peel strength of adhesives, Labthink XLW Tensiletester. This is an universal testing machine, besides tensile test and peel test, it can also used for tear test, seal strength test for hundred kinds of materials.
