Oil-resistant, Acid- And Alkali-resistant Marker Pen Product Usage Scenarios

The various application scenarios of marker pens in industrial marking, because of the different use environments, the effects are also very different. In the hardware and electrical industry, the most commonly used is the surface of metal molds. There are oil stains and use environments that are exposed to oil immersion and wiping. Most marker pens are easily wiped off after marking and soaking in engine oil. After sorting out the use effects of most customers, I tested several pens with relatively good adhesion. After preliminary screening, G-380 can still maintain obvious marking force after being soaked in engine oil. G-380 is an acid and alkali resistant oily marker pen with good oil resistance. Many metal surface marks on molds still have marks after wiping. The acid resistance test has also been done before, and the marks are soaked in sulfuric acid. The markings are still clearly visible after 12 hours.
