The reason glass fibers are sized is to ensure that their filaments are protected during processing, handling, and subsequent composite processing and compounding. Nowadays, waterborne polyurethane is used in sizing to improve the mechanical properties of glass fibers.
Water-based polyurethanes increase the tensile strength of glass fibers and make them resistant to chemicals, impact, and fatigue. Additionally, sizing promotes the hydrolytic and thermal stability of the glass.
SIWO US takes pride in offering waterborne polyurethane solutions to glass fiber manufacturers.
Waterborne Polyurethanes for Coatings
Industrial coatings are essential to painting applied for protective and aesthetic reasons. Polyurethane polymers are used for glass coating and fiber sizing to maintain the quality of the glass. Anionic polyurethane dispersions are suitable for glass coating due to their excellent adhesion to glass and high molecular weight.
Polyurethanes For Glass Fiber Sizing
Waterborne polyurethanes are increasingly used to size glass fibers because of their high binding abilities, tensile strength, and blend stability. It means it creates excellent film by drying and controlling fiber fluffing as a nonionic polymer, it also blends with different materials and its tensile strength makes it high heat resistant.
These glass fibers are used in various industries including marine, aerospace, leisure goods, civil engineering, sporting, construction, and automobile. Their high performance as compared to the cost of manufacturing is their principal advantage.
Our Goal for Sustainable Practice
As a polyurethane manufacturer and water-based polyurethane suppliers across the world, we focus on quality and sustainability. While our product lifecycle involves an intensive quality assurance process, we also continue to eliminate wasteful operations to assure sustainable practice at each stage of our production.
SIWO US emerged as a solution to solvent-based polyurethanes that offered better glass fiber sizing and industrial coating but also had a detrimental impact on the environment. Our waterborne polyurethane addresses the latter issue because water-based polyurethanes are eco-friendly and have low VOC.
Say yes to sustainable practice and project success by switching to our waterborne polyurethane for glass fiber sizing.
