HTAC™ Veil

Characteristics

• HTAC™ technology significantly extends the performance and life of pipes, tankers, and vessels.
• With a tolerance to pH 1-14, HTAC™ outperforms PVDF and PTFE, providing superior corrosion resistance.
• HTAC™ is engineered to withstand high temperatures and fire exposure.
• Available in a range of weights and apertured versions, offering flexibility for diverse applications.
• Ideal for chloro-alkalis chemical processing, semiconductor fabrication, and pharmaceutical industries.

Case Study: Composites USA

HTAC™ Veil – Apertured ECTFE Meltblown media is effectively being used as a surfacing veil in specialized FRP ventilation system components. HTAC Veil will withstand high temperatures and resist corrosion and abrasion in ducting for semiconductor manufacturing.

The HTAC Veil 3.0 osy is specified and has been used by Composites USA, North East, MD, USA in the corrosion barrier of their Dual-Guard 2000 FRP ducting used in clean rooms of semiconductor plants.

This duct will withstand corrosive fumes and smoke exhausts and bears the Factory Mutual 4922 test approval #4B1A5.AM as a Non-Sprinkled smoke removal duct and the Factory Mutual 4910 test approval #3003307 as a Clean Room material.

In addition, the duct is listed by Underwriters Laboratories per U.L. 181 as a Class 1 Air Duct material report demonstrating compliance with the Uniform Building Code and the B.O.C.A. Code.

The use of the HTAC Veil and a phenolic resin not only gives the corrosion resistance, but also achieves a Flame Spread index of 5 and a Smoke Development of 10, per the ASTM E-84 tunnel test.

Case Study: Tankcon FRP, Quebec, Canada

An FRP demonstration tanker was fabricated in January, 2024 by Tankcon FRP, Blainville, Quebec, Canada. The tanker is five feet in diameter by 40 feet long. Fabrication was by hand layup.

After spraying the Derakane Signia 510C resin with a BPO-DMA cure on the mandrel, one layer of the

HTAC Veil 3.0 osy was applied from a 50-inch-wide roll. Then a C-veil followed by two plies of ECR mat were applied to achieve a 110 mils corrosion barrier. Derakane Signia 510C resin with an MEKP cure was used for the structure. The finished FRP tank was postcured using hot air from a salamander heater to achieve the full curing.

This demo tanker is rented to Brentagg Distribution, Toronto, Ontario, Canada, to haul a 20% sodium hypochlorite solution across North America. The tanker will be inspected at six-month intervals to evaluate the performance of the HTAC Veil 3.0 osy.
