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. SE2020 Direct Rovings made of Advantex® glass are specifically designed for the production of Non Crimped Fabrics. The sizing of SE2020 Direct Rovings is specifically designed for excellent adhesion with epoxy resin systems. SE2020 Direct Rovings made of Advantex® glass present high level of fatigue performances, superior inter-fibre strength and interlaminar shear. The SE2020 roving is approved by Germanischer Lloyd for the use in wind-turbine rotor blades. SE2020 Direct Rovings made of Advantex® glass can allso be used in prepreg, filament winding process 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.
