DP40lf; what additive?

I found several quarts of DP40lf primer that I'd like to use. What activator do I need?

DP401LF or DP402LF

 

Note that the 401 hardener has to be added at least 1/2 hour before it can be sprayed. The 402 does not have an induction time required and can be sprayed right away. Pot life is also longer with 401.

 

that's good to know---thanks.

 

Use the 401, it makes dplf a decent epoxy. Avoid the 402.
