Topcoats
Series 1, 21, 27, 46H-413, 66, L69, L69F, N69, N69F, V69, V69F, 73, 104, 113, 114, 115, V115, L140, L140F, N140, N140F, 141, 161, 406, 1028, 1029, 1094, 1095, 1096.
Note: If Series 1 is exterior exposed for one year or more it must be scarified or recoated with itself before topcoating. Scarification or recoating with itself is required if the Series 1 has been exterior exposed for three days or longer and Series 113 is the specified topcoat. Note: Series 115 and V115 require Series 44-900 adhesion promoter when topcoating Series 1. Note: Certain topcoat colors may not provide one coat hiding depending on the method of application. Contact your Tnemec representative. Note: Series 1 requires three days exterior exposure before topcoating with Series 1028 or 1029.
Curing Time
Without 44-710
| Temperature †|| To Touch || To Handle || To Topcoat |
| 75°F (24°C) || ¼ hour || 1 ½ hours || 16 hours |
| 65°F (18°C) || ¼ hour || 2 ¾ hours || 16 hours |
| 55°F (13°C) || ¼ hour || 5 hours || 20 hours |
---† 50% Relative Humidity. Note: Refer to product listings on www.nsf.org for specific potable water return to service information. Curing time will vary with surface temperature, humidity, and film thickness. Note: When recoating Series 1 with itself, the minimum recoat time is 2 hours at 70°F (21°C).
Ventilation: When used in enclosed areas, provide adequate ventilation during application and cure.
With 44-710: The use of 44-710 can greatly reduce dry to handle cure times. Note: Series 44-710 Accelerator must be used when the surface temperature falls below 50°F (10°C).
