Adhesion testing is performed to maintain quality control process in the manufacturing units. It is also done to adhere the production as per the industrial standards and customer demands. Depending upon various applications, the need for maintaining the adhesion strength varies. Paint and coating application can range from a small consumer product to the large scale productions in an industry. But the common factor between both is an untimely failure of adhesion that has a substantial cost. The most popular adhesive failure in automotive industry involves failure of paint and coating on a particular material.
Adhesion testing is done to determine the resistance of paint and plating to separation from a material when the tensile force is applied to it. Coated substrates can be anything, i.e. plastic, metal, concrete, glass or wood. Generally, coating, lining, and finishes are totally different as they are done with different things which include, powder coating, paint films, UV curved, epoxies, ceramics, thermoplastic resins like plastisols, vinyl and polyethylene, varnishes, laminates, lacquers, elastomers and specialty resin like polyesters, phenolics, etc.
There are very few applications and industries that are defined in the standards, but adhesion testing is done for all paint and plated products and is widely done by the manufacturers of paint and plating industry. The expected results of adhesion testing are determined by the concerned manufacturers. Depending on the repeatability and accuracy of test results, numerous variations are recorded between the different testing equipment and hence considered by the manufacturers accordingly. To minimize these variations, it is necessary to utilize the best testing equipment supplied by a reputed supplier to enhance the quality of the production. Conical Mandrel Bending testing instrument is specially designed to fulfill the same purpose.
The conical mandrel bending laboratory test equipment is widely used to cure the coated test specimens over a cone-shaped mandrel of the instrument to judge the resistance and elasticity, elongation or detachment, finish to cracking properties of painted and coated substrates as per domestic and international standards ASTM D522 and ISO 6860. It is also used to analyze the sticking properties of coated material deeply when the sample is subjected to bending stress. The conical contour of the instrument permits deformation of a panel to examine the elasticity range of the coating. The thickness of any rupture in the paint or coating and the distance of break from the small end, from where it cracks, is then measured as its coating resistance for a comparative result.
