Series 394 | PerimePrime

Generic Type Aromatic Polyurethane, Mio-Zinc Filled Primer
Common Usage Specially formulated, one-component, moisture-cured, micaceous iron oxide and zinc filled primer that offers superior bonding to marginally prepared rusty steel and tightly adhered old coatings. This high performance primer is ideal for corrosion resistance with a triple barrier mechanism of zinc, mio and urethane resin built into the dry film. It is suitable as a corrosion resistant primer under certain fireproofing systems. Contact your Tnemec representative for specific information.
Colors 0250 Greenish-Gray
Primers Self-priming, 90-97, 90G-1K97
Topcoats Series 27, 27WB, 66, 66HS, L69, L69F, N69, N69F, 73, 113, 114, 115, 161, 161HS, 740, 750, 1026, 1028, 1029, 1074, 1074U, 1075, 1075U.
Note: If Series 394 is exterior exposed for 1 year or more it must be scarified or recoated with itself before topcoating. Scarification or recoating with itself is required if the Series 394 has been exterior exposed for 3 days or longer and Series 113 is the specified topcoat. Note: Series 115 requires the use of Series 44-900 adhesion promoter when topcoating Series 394. Note: Certain topcoat colors may not provide one coat hiding depending on method of application. Contact your Tnemec representative. Note: Series 394 must be exterior exposed for one day prior to topcoating with 27WB or three days prior to topcoating with 1028 or 1029.
