Core Advantages
1. Fully hydrolyzed film owns far better water & abrasion resistance than BP series; less size shedding after washing of pure cotton fabric.
2. Excellent affinity to cotton, viscose & rayon; stiff & smooth sized yarn with low breakage rate during weaving.
3. No delamination or collapse after water contact for water-resistant paper coating & waterproof cardboard forming.
4. High bonding strength of water-based wood waterproof adhesive without debonding under humid environment.
5. Good barrier property of film after emulsion polymerization, oil & water resistance for packaging printing.
