PENNTROWEL™ Vinyl Ester L/F System - Silica and Carbon Grade

1/8 in Mat Reinforced Vinyl Ester Lining

PENNTROWEL Vinyl Ester L/F System is a nominal 1/8 in – 3/16 in multi layer monolithic lining system that offers the benefits of increased strength and chemical resistance by incorporating 10 oz woven glass mat reinforcement and multiple layer build into the lining. PENNTROWEL Vinyl Ester L/F utilizes a vinyl ester novolac backbone resin for maximum service temperature and chemical resistance. It is packaged with pre- proportioned graded fillers based on either quartz or carbon aggregates (for strong caustic or hydrofluoric acid service).

The system has been formulated to perform in chemical immersion service, and to withstand the various temperature extremes that can be encountered in sumps, trenches, pits and vessels. For complete installation details, consult Corrosion Engineering installation specification CES 352.


PENNTROWEL Vinyl Ester L/F System is used both in and out-of-doors to protect concrete and steel substrates from to a wide variety of corrosive agents, including: oxidizing and non-oxidizing acids, salts, oils, (mineral and vegetable) and many alkaline-based cleaners, as well as organic solvents.

• manways
• floors

Note: Use PENNTROWEL Vinyl Ester L/F Carbon System in hydrofluoric acid service.
