3B Direct Rovings consist of continuous filaments bonded into a single strand and wound onto a bobbin shape. A proprietary sizing applied on the fibres assures an excellent resin-to-glass bonding. Corrosion resistant 111A Direct Rovings made of Advantex® glass are specifically designed for weaving processes. The silane sizing of 111A is specifically designed for excellent adhesion with thermoset resins and is also drinking water contact approved. 11A Direct Rovings made of Advantex® glass are also used in filament winding process and in production of uni-directional fabrics under specific conditions; contact us for further assistance.

Advantex® glass is a boron-free glass and presents significantly improved corrosion resistance across a wide range of aggressive environments. Advantex® glass is an E-CR glass in accordance with ASTM D578 and ISO 2078. This translates into important benefits for end-users over traditional E glass: longer service life, larger safety coefficients for the same design, and material savings. Traditional E-glass includes boron and often contains added fluorides. By using new manufacturing technology to eliminate these components from the glass composition, Advantex® glass has become a benchmark for integrated pollution prevention and the highest energy efficiency, all in an optimized process. 3B measures its efforts and works continually to minimize its impact on the environment and to set new standards within the global fibreglass industry. This is our commitment.
