CCP Changchun BF-03 (0399) Ultra-Low-Viscosity Fully Hydrolyzed Polyvinyl Alcohol for Remoistenable Glue & Printing Colloid

Full Name: CCP Changchun BF-03 Ultra-Low Viscosity Fully Hydrolyzed Polyvinyl Alcohol (Model 0399) Lowest viscosity fully hydrolyzed grade in BF series with hydrolysis degree 98~98.8%; formed film owns better water resistance than BP series, suitable for low-viscosity & high water-resistance paper & printing systems, only dissolvable in hot water above 85℃. Core Technical Parameters Viscosity (4% aqueous solution, 20℃) 3~4 mPa·s Degree of Hydrolysis 98~98.8 mol% Appearance   White pellets / customizable powder form Volatile Content ≤5.0 % Ash Content   ≤1.0 % pH Value (4% aqueous solution) 5~7 Purity ≥99.0 % Standard Package 20kg/bag CAS No. 9002-89-5   Core Advantages 1.Ultra-low viscosity ensures good fluidity under high dosage without roller blockage in high-speed printing & coating lines. 2.Fully hydrolyzed molecular structure provides superior water & grease resistance of dried film compared with BP series. 3.Fast activation by water for remoistenable glue; stable viscosity without overflow for stamp & label back glue. 4.Water-resistant film formed as emulsion protective colloid, suitable for outdoor water-based printing ink. 5.Strong penetration of low-viscosity slurry for uniform impregnation without accumulation on thin paper & filter paper. Main Application Fields Core Applications: Stamp / label remoistenable back glue, low-viscosity water-resistant printing ink protective colloid, thin paper impregnating agent Compatible Fields: Water-resistant indoor coating additive, small ceramic part binder, water-soluble printing varnish Forbidden Scenarios: Oral food raw materials, production lines requiring ambient-temperature low-temperature dissolution, hydrophobic chemical fiber sizing (weak adhesion)
