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
75°F (24°C) 4 hours 48 hours 5 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.
