I have several cans of PPG DP epoxy primer and catalyst but don't know what they mix with. I think I have figured out the DP LF but still not sure about the DP 402. Can I use the 402 with the DP 74 LF Or do I need to a primer that is not in the LF class? I know the LF series needs to be allowed to sit for 30 minutes to activate but the straight 402 can be sprayed immediately.


I understand the K 201 is a catalyst for the High Fill Primer, just ordered a Qt. of K 36 High Fill primer. What do I need to use up my DP 402 catalyst, or do I already have it???
