PVA 098-60 Application
PVA 098-60 is a high-viscosity, fully hydrolyzed PVA grade with high molecular weight.
Used for high viscosity adhesive
PVA 098-60 is a core raw material for high-viscosity, high-performance water-based adhesives. Its high-molecular structure delivers powerful thickening capacity, excellent initial tack, and stable ultimate bonding strength. It forms tough, transparent and durable adhesive films with outstanding water resistance and aging resistance. It is ideally applied for wood bonding, paper composite lamination, heavy-duty packaging adhesion and various high-viscosity structural adhesive systems.
Used for industrial coatings
As a premium functional additive for high-end coatings, it possesses excellent thickening, anti-settling and leveling properties. It stabilizes pigment dispersion uniformly, improves construction workability, and effectively prevents coating delamination and precipitation. After curing, it significantly enhances coating hardness, abrasion resistance, water resistance, and weather durability, greatly improving surface smoothness and the comprehensive performance of high-grade architectural and industrial coatings.
Used for textile wrap sizing
With outstanding film toughness and strong fiber adhesion, it is specially suitable for sizing high-count and high-density yarns. It forms dense, smooth, and wear-resistant protective films on yarn surfaces, effectively improving yarn tensile strength and friction resistance during weaving. It maintains stable sizing performance and allows thorough desizing without affecting subsequent finishing processes.
Used for high-performance building materials
PVA 098-60 works as a key modifier for high-standard dry-mix mortar, wall putty, and architectural coatings. It provides excellent water retention, thickening and anti-cracking performance, improving construction usability and substrate adhesion. It effectively enhances the compactness and long-term durability of building materials, preventing common defects such as peeling, hollowing and dry-shrinkage cracking.
