Series 1448
Vinester
Generic Type
Novolac Vinyl Ester
Common Usage
A high-build, vinyl ester lining with corrosion resistant graphite fillers. Use where silica free coatings perform best, such as high alkali environments, spent bleach solutions and hydrofluoric and fluosilicic acids, in elevated temperature conditions for both dry, fume and wet services. The graphite also provides good electrical conductivity and is a high wear finish.

Primers
Self-priming on steel or Series 1402, 1407. Note: For services above 180°F (82°C), do not use a primer.
Surfacer/Filler/Patcher
Series 215, 217, N218, primer with 211-9111 or fumed silica. Note: Series N218 should be used for filling or patching small areas only. For areas in need of full resurfacing, select one of the other recommended products.
Curing Time
| Temperature | To Recoat | Immersion | Maximum Recoat |
|---|---|---|---|
| 90°F (32°C) | 3 hours | 24 hours | 3 days |
| 75°F (24°C) | 4 hours | 48 hours | 5 days |
| 60°F (16°C) | 12 hours | 4 days | 7 days |
Recoat times are typical for coating to be dry-to-touch and ready for the next application. Immersion and certain other services may require longer cure times and/or elevated temperature post cure for optimal performance. ASTM D2583 Barcol Hardness check is also recommended, minimum 20. Coating that has exceeded its maximum recoat time should be checked for styrene or acetone sensitivity or uniformly scarified to assure secondary bonding. Consult Tnemec Technical Services and Technical Bulletin 22-119 R1.
