Series 1444
Vinester
Generic Type
Novolac Vinyl Ester
Common Usage
A high-build, vinyl ester lining with corrosion resistant graphite and other specialty fillers to create a low surface energy film imparting a high degree contact angle resulting in improved non-stick characteristics. Use this enhanced, silica-free material in prevention of process material build-up such as fly ash, caking by-products and slurry deposits. Save time and costs with the improved cleaning properties of this coating versus other non-release type linings. An ideal finish coat for hot caustic and non-silica preferred lining applications such as hydrofluoric acid.

Curing Time
| Temperature | To Recoat | Immersion | Maximum Recoat |
|---|---|---|---|
| 90°F (32°C) | 3 hours | 24 hours | 3 days |

Note: Certain service applications may require elevated temperature cure for maximum performance. 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. Consult Tnemec Technical Services.
