Nexstar continues to invest in research and development to create synthetic filament blends designed to reproduce key performance characteristics of natural bristle. By combining tapered synthetic filaments with different diameters and geometries, Nexstar can influence product release, application uniformity, softness and feel during use.
Nexstar's research also focuses on the requirements of professionals accustomed to using brushes made with 100% natural bristle.
These users are not simply looking for a material that visually resembles natural bristle, but for synthetic solutions capable of providing comparable characteristics and performance during use.
For this reason, Nexstar has developed specifically designed synthetic filament blends, combining filaments with different diameters, taper profiles and geometries.
Beyond simply replacing natural bristle
Simply replacing part of the natural bristle with conventional synthetic material does not necessarily provide the same feel and performance required by professionals accustomed to brushes made with 100% natural bristle.
Natural bristle has a characteristic tapered profile, with the diameter changing along its length. This contributes to the way a brush behaves during application, including its flexibility, product release and overall feel.
Nexstar's research therefore focuses on reproducing these functional characteristics through synthetic filaments with carefully designed taper profiles and different diameters. By combining filaments with different characteristics and geometries, it is possible to develop synthetic blends that more closely reproduce the behaviour of natural bristle.
New synthetic filament blends and the development of Vibris
Nexstar has developed new synthetic filament blends that represent a further evolution of Vibris, with improvements in appearance, feel during use and performance.
These solutions are designed to increase the amount of product released by the brush and provide highly uniform application, while maintaining a feel similar to that associated with robust natural bristle.
Softness, loading capacity and finish quality
Nexstar has also developed synthetic filament blends designed to reproduce the softness associated with finer natural bristles, while maintaining good product-holding capacity and uniform release.
These characteristics make them particularly suitable for paints, stains and wood coatings with matt, satin and chalky finishes.
The ability to hold and release the appropriate amount of product can make application more efficient and contribute to a uniform, high-quality finish. Combining synthetic filaments with different diameters, taper profiles and geometries also makes it possible to create a dense and homogeneous brush with a pleasant feel during use.
