ASTM D7187 Temperature Effect Using Nanoscratching

ASTM D7187, the resistance of the paint to scratch and mar plays a vital role in its end use. Automotive paint susceptible to scratches makes it difficult and costly to maintain and repair. Different coating architectures of the primer, basecoat, and clearcoat have been developed to achieve the best scratch/mar resistance. Nanoscratch testing has been developed as a standard test method to measure the mechanistic aspects of scratch/mar behavior of paint coatings as described in ASTM D7187. Different elementary deformation mechanisms, namely elastic deformation, plastic deformation and fracture, occur at different loads during the scratch test. It provides a quantitative assessment of the plastic resistance and fracture resistance of the paint coatings.

Paint Drying Morphology Monitoring Using 3D Profilometry

Paint is usually applied in a liquid form and progressively dries into a solid. The drying process involves evaporation of the solvent and formation of a solid film. The paint surface progressively changes its shape and texture during the drying process. Different surface finish and texture can be developed by using miscellaneous additives to modify the surface tension and flow properties of the paint. However, undesired failures of the paint may occur in the cases of bad paint recipe or improper treatment of the surface. Accurate in situ monitoring of the shape evolution during the paint drying period can provide direct insight into the drying mechanism. Moreover, real-time evolution of surface morphologies is very useful information in various applications, such as 3D printing. The Nanovea 3D Non-Contact Profilometer measures the surface morphology of materials without touching the sample, avoiding any shape alteration which may be caused by contact technologies such as sliding stylus.

Industrial Coating Scratch & Wear Evaluation

The wear process of the acrylic urethane floor paints with different topcoats is simulated in a controlled and monitored manner using the Nanovea Tribometer as shown in Fig. 1. Micro scratch testing is used to measure the load required to cause cohesive or adhesive failure to the paint. In this study, we would like to showcase that Nanovea Mechanical Tester and Tribometer are ideal tools for evaluation and quality control of commercial floor and automotive coatings.

Textile Abrasion Wear By Tribometer

The measurement of textile abrasion resistance of fabrics is very challenging. Many factors play a role during the test, including the mechanical properties of the fibers, the structure of the yarns and the weave of the fabrics. This may result in poor reproducibility of test results and create difficulty in comparing values reported from different laboratories. Wear performance of the fabrics is critical to the manufacturers, distributors, and retailers in the textile production chain. A well-controlled quantifiable and reproducible Tribometer wear resistance measurement is crucial to ensure reliable quality control of the fabric production.

Textile Texture Measurement Using 3D Profilometry

Understanding textile texture, consistency and patterns of the fabrics allows the best selection of processing and control measures. Traditional stylus-based profilometers determine the surface morphology of the coatings by sliding in contact across the measured surface, which may deform the soft fabric and induce inaccurate measurement. The Nanovea 3D Non-Contact Profilometer utilize chromatic confocal technology with unmatched capability to provide a comprehensive analysis of the surface feature of fabrics, making it an ideal tool for reliable product inspection and quality control.
