Adhesion Test Apparatus Model 525 - ERICHSEN

Detailed Overview

The Adhesion Tester, Model 525, is a premier tool designed to measure adhesion according to ASTM D 4541. This model is compatible with all coating materials that can adhere to a test cylinder using existing adhesives. Its entirely mechanical design requires no electrical supply, rendering it perfect for mobile field applications.

Boasting a robust construction and user-friendly operation, the Model 525 excels under the most severe conditions. By employing a test cylinder (dolly) affixed to the coating with an adhesive, and measuring the tensile strength required to detach it, this apparatus provides critical insights into the adhesive quality of coatings.

Unlike other methods, the adhesion test delivers distinct results by applying force perpendicular to the coating surface, rather than through shear forces. This accurate and reliable equipment is crucial for industries requiring stringent quality control measures for their coating applications.

Frequently Asked Questions

What is the Adhesion Tester Model 525?
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.
What are the technical specifications of the Model 525?
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.
How does the Model 525 measure adhesion?
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.
Can the Model 525 be used in field applications?
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.
Is the Model 525 suitable for all types of coatings?
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.
What makes the Model 525 unique compared to other adhesion testing methods?
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.
How robust is the construction of the Model 525?
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.
