PVA 1788 is a medium-viscosity, partially hydrolyzed polyvinyl alcohol recognized for its balanced performance across adhesion, film strength, and processing stability. With viscosity typically ranging from 20–26 mPa·s and hydrolysis between 86–90%, this grade offers excellent water solubility at ambient conditions while delivering strong cohesive strength after drying. It is commonly applied in textile sizing, where uniform film formation improves yarn abrasion resistance and weaving efficiency. In paper coating and surface treatment, PVA 1788 enhances smoothness, printability, and binding strength. Construction-related uses include putty powders and general-purpose water-based adhesives, where consistent viscosity control is essential for workability. The material’s compatibility with fillers, plasticizers, and other polymers allows formulators to adjust performance without sacrificing stability. Due to its versatility, PVA 1788 is often selected as a standard grade for multi-purpose production lines.
