Wornow SR1000 Solder Mask

[tarun172]

Hi,
I was asked to find out if a regular soldermask could be used instead of Wornow SR1000. I have a drawing that specifies this particular soldermask, and I have been unable to find an equivalent one. Is anyone aware of whether the Wornow SR1000 solder mark is still used in the PCB industry as a soldermask resist? Are there any alternatives?

Thanks,
Tarun S
