Scratch & Shear Resistance Testers evaluates resistance to shearing, scratching, gouging, marring, scraping and engraving. It is used in quality control, materials and product development, the applications are diverse. It is ideal for evaluating adhesive qualities of surface coatings, detecting the lack of homogeneity in comparative materials, rating similar or competitive materials, or analyzing the effects of age under controlled environmental conditions. Precision, calibrated weights provide a flexible testing range for a variety of products. It test rigid organic materials, adhesive coatings, paints, powder coatings, anodized materials, soft metals, synthetics, linoleum, laminates, plastics, glass, plus many others. It offers tremendous versatility to simulate abrasion and scratch resistance of virtually any product. It incorporates a horizontal arm that reciprocates in a linear motion. It allows the operator to conduct wear tests using an abradant the diameter of a pencil eraser and to expand the range of testing, a variety of optional interchangeable attachments are available to evaluate a products resistance to scratch, gouge, scrape, rub, mar, coin scrape, and crock testing.
