Exilva improves cold weather painting opportunities
(16.09.15) Exilva is Borregaard’s innovative new microfibrillar cellulose (MFC) that decreases mud-cracking in exterior acrylic paint when applied in cold weather.
Mud-cracks are a phenomenon occurring when paint is applied too thickly or allowed to build up in corners during application, or when the surface is not properly repaired. Mud-cracks look like irregular cracks in a surface, resembling cracks in dried mud. New tests in acrylic exterior paints, conducted by Marschall labs (US), show that Exilva reduces the tendency for mud-cracking during drying of acrylic pigmented systems (see Figure 1). This in turn provides the opportunity to reduce coalescent levels and related VOC levels in paint.
Exilva®, a Microfibrillar/Microfibrillated Cellulose (MFC), is characterised by its ability to form stable three-dimensional networks of microfibers in solvents and is a unique solution for high quality products. The secret behind Exilva’s® excellent performance, is its unique combination of characteristics from soluble polymers and insoluble particles, enabling it to both physically and chemically interact with its surroundings.
Borregaard operates one of the world's most advanced biorefineries. By using natural, sustainable raw materials, Borregaard produces advanced and environmentally friendly biochemicals and biomaterials that replace oil-based products. The Borregaard Group has 1080 employees in 16 countries.
