This 1:1 Two-part, high-solids epoxy primer is an ideal coat under high-gloss urethane topcoats to maximize adhesion, improve gloss, and aid in gloss retention. We say improves gloss and aides in gloss as epoxies once topcoated too soon tends to cause dye back issues.
This epoxy will not have those issues. Dries quickly for faster overcoating, easy to sand once cured, (in as little as 3 hours above 70) and provides excellent corrosion control.
The Surfacing primer formula is ideal for easy sanding, very high build uses on all substrates. Ideal for a underwater marine primer, but not solely intended for marine use. This epoxy can be used on ANY substrate. The 770 series epoxy unlike our HP660 series epoxy is solely Direct to rust! 3 coats of this epoxy is all the protection you need against rust!
Our 660 series epoxy was always a “sealer” coat epoxy. Never intended for build, you always needed to use our 53xx primer over it (at least 12 hours later) for the build and sandable properties. You no longer need to do that with this unique epoxy.
You now have a new option!
If you want a high build, quick sanding, non shrinking epoxy. Consider the 770 series epoxy
