Epoxy vs urethane primer
The Nason 491-10 epoxy primer needs 60 min. before a 2nd coat and has up to 48 hours for a topcoat without sanding. I assume "topcoat" in that case means the urethane 2K primer also? The Nason 421-10 urethane primer will then go over that and needs to flash 8-10 min. between coats and max. flash of 2 hours without sanding.Urethane and epoxy are polymers. Both products have big molecules that repeat structure and link. Epoxy resins are epoxide, polyamine, and hardener. Urethane, a carbon-based substance produced from organic linkages, reacts with monomer. Uses; Urethane is majorly the auto body primer. Consistency of urethane makes it easy to sand and fill minor ...Thornton, CO. Apr 28, 2008. #5. I'm not a paint expert, but I will pass on what I have read. Epoxy primer is used on bare metal (it is like an etching primer). It is a 2 part paint, meaning it has a catylist. It does not sand well, so it is merely a place to start for bare metal. Urethane primer is a sandable primer.
