Handling
Stir well the 10% solution before application.
We suggest to cross-link the primer with isocyanate to improve cohesion and anchorage of the adhesive tape. CURING AGENT RF/AEDE, CURING AGENT D or CURING AGENT CH (Ichemco) should be added, remembering that the pot-life of the primer will be reduced, as the crosslinking mechanisms starts immediately after the addiction of the isocyanate.
Ratio between isocyanate and PRIMER EPA-SOL (10% solution): 0.5 -1.5 %.
