Adhesion Test Apparatus Model 525 – ERICHSEN

The Adhesion Tester, Model 525, is an advanced instrument designed to measure the adhesion strength of coatings as per ASTM D 4541 standards. It is suitable for use with any coating materials that can adhere to a test cylinder using adhesives, functioning entirely mechanically without the need for electricity, which makes it ideal for field applications.

The Model 525 features manual drive, a scale of 0.5 N/mm² and 100 lb/in², a 20 mm dolly diameter, testing force range of 0-5 N/mm², measuring area of 5 N/mm² and 700 lb/in², with a total weight of 3.0 kg in the carrying case, and the testing instrument alone weighs 1.2 kg. Its dimensions in the carrying case are approximately 350 x 265 x 85 mm (L x W x H), while the device itself measures about Ø 82 x 185 mm.

The Model 525 measures adhesion by employing a test cylinder (dolly) that is affixed to the coating surface with an adhesive. It then measures the tensile strength required to detach this cylinder from the surface. This force is applied perpendicular to the coating surface to accurately measure adhesion strength.

Yes, the Model 525 is perfectly suited for mobile field applications. Its entirely mechanical design requires no electrical supply, allowing it to be used in various locations without the need for power connectivity.

Yes, the Model 525 is designed to work with all types of coating materials that can adhere to a test cylinder using conventional adhesives. It is a versatile tool for assessing the adhesion quality of a wide range of coatings.

Unlike other testing methods that might apply shear forces, the Model 525 applies force perpendicular to the coating surface. This approach provides more accurate and reliable measurements of the coating's adhesion strength, making it an essential tool for industries that require strict quality control over their coating applications.

The Model 525 is constructed to withstand severe conditions, making it highly durable and reliable for rigorous testing environments. Its robust construction, combined with user-friendly operation, ensures long-term and efficient performance in testing coating adhesion strength.
