90° Peel Testing (Adhesion)

ASTM D6862/D3330

Peel testing (ASTM D6862) and adhesive tape test (ASTM D3330), is a type of test used to measure the peel strength of coatings and tapes. It is a destructive test that involves peeling the coating, shell material or tape off while maintaining a 90-degree angle.

Do you want to know the adhesive strength of your paint, tape or elastic shell such as LEPs?

What is Peel Testing?

The force required to remove the tape is measured and used to determine the coating’s energy release rate (peel strength). The peel strength of a coating is an important indicator of its adhesion properties, and it can be used to evaluate the coating or tape’s performance and durability.

Peel testing can be used to test a variety of coatings, tapes and bonded polymeric shells.

The equipment used for peel testing can vary, but it typically involves a tensile testing machine and a strip of adhesive tape.

Peel testing is a quick and easy way to evaluate the adhesion properties of coatings and it can be used to compare the performance of different coatings or to monitor the performance of a coating over time. In summary,

Peel testing is a destructive method used to evaluate the adhesion strength of coatings by measuring the force required to remove an adhesive tape from the coating.

This test is commonly used to evaluate the performance and durability of coatings and it can be done on different substrates, scales and thickness of the coating.

Tailored to your needs

There are different types of peel testing methods, depending on the type of coating and the material being tested.

The most common method is the 180-degree peel test, which is used to measure the force required to remove a strip of tape from the coating.

This method is suitable for tapes that have a thickness of less than 1mm.

Another common method is the 90-degree peel test, which is used for coatings that are thicker than 1mm.

Peel testing can be performed on a variety of substrates, such as metals, plastics, and composites, and it can be done on a variety of scales, including small coupons, full-size panels, or entire structures.

Combine and Conqueur

It is important to note that peel strength is only one aspect of coating performance, and it should be combined with other tests to fully evaluate the coating’s performance and durability.

We offer non-destructive coating fatigue testing in combination with peel tests to test and compare how dynamic fatigue of the coating affects it’s adhesive strength.
