The decision as to whether a colored or fluorescent penetrant test should be favored usually depends on several factors. In addition to the probability of detection, the environmental requirements or the cost factor, it also depends on the nature of the workpiece surface, component compatibility and the properties of the test equipment. In addition, test conditions, customer requirements or specifications must be adhered to. There is therefore a lot to consider when choosing a suitable penetrant.<\/p>\n\t\t\t\t\t<\/div>\n\t\t\t\t\n\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

At MR Chemie, we offer numerous alternatives with our wide range of product families for many applications, whether colored or fluorescent. Without going into too much detail, which is difficult due to the extensive subject matter, I would like to give you a brief overview of our available penetrant types.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Note<\/u>: A precise description of the required test agent properties for the respective areas of application can be found, for example, in the DIN EN ISO 3452 series of standards.<\/em><\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

In the Type I variant, i.e. the purely fluorescent penetrants, you will find products in sensitivity classes 0.5 to 3 with approvals according to ISO, AMS, ASME, PMUC, RCC-M and also for the NSF area. The test agents are solvent- or oil-based and some are also available in the container form as Eco-Line products, i.e. label-free.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Type III penetrants, colored and fluorescent, are available in sensitivity class 2, classified according to the dye penetration test system. In addition to the solvent and oil-based variants, our MR\u00ae 67<\/a> is also available as a water-based test agent.<\/p>\n

For component temperatures above 100\u00b0C, our MR 68 H<\/a> is also available, as is our MR\u00ae 312<\/a> for component temperatures down to -30\u00b0C.<\/p>\n

\n\t\t\t\t\t\t\t\t\tThe choice of a suitable test agent is difficult to generalize and must always be made on an individual basis. We offer solutions for many applications, whether aerosol-based, in containers or for fine applications in the form of our Piccolo and Jumbo Pens. The appropriate cleaners and developers, as a sample-tested product family, as well as a comprehensive range of accessories for applying and removing test agents are available from us, as are the devices for monitoring the test parameters. Our test agents are suitable for many materials such as metals, plastics, ceramics and glass.\r\n\r\nIf you are interested, or if you have any questions or suggestions, please contact us and let us work out a suitable solution for you.\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
