HTAC™ Veil

ECTFE Apertured Veil

This binder free apertured veil is produced with meltblown ECTFE (ethylene chlorotrifluoroethylene) fluoropolymer resin.

HTAC Veil provides a corrosion barrier for fiberglass reinforced plastic (FRP) tanks, tankers, scrubbers, pipes, ducts, and stacks. 

Superior to other veils on the market, the benefits of HTAC Veil include very high chemical and abrasion resistance at high temperatures, and excellent fire retardancy (flame spread index of 0 per ASTM E-84).

Product characteristics include very high chemical resistance against strong acids, sodium hydroxide, sodium hypochlorite, chlorine dioxide and solvents.

With a high permeation resistance, it reduces blistering in hot concentrated hydrochloric acid. It has an apertured hole pattern of IPS-10 and is easy to inspect in a 100 mil FRP corrosion barrier.

HTAC Veil is easy to laminate and wet-out. It can be applied by both hand lay-up and roll/tape winding in an orthowinding or filament winding process.

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.
