Advanced Polymer Inc. (API), of Carlstadt, New Jersey, US, has introduced APW-342C, a water-based emulsion concentrate that can be used to produce a one-step cleaner, polish and surface protectant for stainless steel. APW-342C dries quickly, leaving a self-healing, durable film that resists fingerprints, smudges, dust and dirt. APW-342C can be formulated for “spray and wipe” or application via pre-moisten towelettes.
