摘要:
An electrodeposition process is provided for applying an elastomeric thermosetting, film-forming polymer to a corrosion-resistant electrically conductive substrate that is free of an electrodeposited coating. The elastomeric polymer typically is a polyurethane, a polyurea or a poly(urethane urea). The film-forming coating applied by this process provides chip resistance to the substrate. A coated article that is prepared according to the process is also provided.
摘要:
A method for determining the thickness of a dryable or curable film-forming coating by incorporating a fluorescent component into the coating. The fluorescent component is either a resin solid of the coating, a fluorescent dye or a fluorescent dye attached to a resin solid of the coating. The coating is exposed to ultraviolet or visible light which causes the fluorescent component to fluoresce. The intensity of the fluorescence of the coating is measured and the thickness or weight of the coating is determined from a known mathematical relationship between the fluorescence intensity of the coating when exposed to the light and the thickness or weight of the coating. Additionally, a curable or dryable film-forming coating composition including a curable or dryable organic resin reacted with a fluorescent tag is provided.
