PM-500 WUA 特种UV固化字符油墨UV Curable Marking Ink
PM-500 WUA是专门为PCB客户开发的双组份特种UV固化字符油墨。该产品特别适合用于双面字符板，
在防焊显影成像后先印刷第一面字符，UV预干后，即可印刷第二面。第二面可采用传统热固字符油墨，
丝印后直接高温热固化；若使用本品，丝印后UV固化再加高温热固化。较传统UV字符比，此产品兼有
热固字符的白度高，附着力好，耐热及耐化学性能优良等特点。
PM-500 WUA is a two-component special UV curing character ink specially developed for PCB
customers.This product is especially suitable for double-sided character board. The first
character is printed after anti-welding imaging, and the second character can be printed
directly after UV predrying, and then into UV and high temperature curing.Compared with
traditional UV characters, this product has the advantages of high whiteness, good adhesion,
good heat and chemical resistance.
