Key Characteristics and Applications
- Grade Details: PVA 2299 has a high degree of hydrolysis (approx. 98.0–99.9%), indicating it is fully hydrolyzed, with a high viscosity (often between or higher depending on the manufacturer).
- Construction/Building: It is used as a modifier in cement, dry-mix mortars, and building adhesives, providing high-strength bonding, increased water retention, and improved workability.
- Adhesives & Coatings: Due to its excellent film-forming properties, it is used in paper sizing, PVA adhesives, and adhesive applications.
- Textiles: It acts as a warp sizing agent in the textile industry.
- Physical Form: Commonly supplied as a white to light yellow flocculent, powder, or granule.
- Storage: It is highly soluble in hot water and should be stored in dry, well-ventilated areas to prevent moisture absorption.

Are PVC and PVA the same?
PVC-E (poly (vinyl chloride)) is softer and more rubbery, and more hydrophobic or water repellent, while PVA (poly (vinyl acetate)) is harder and stiffer, with a more wettable surface and a greater tendency to absorb a little water and become a little softer.Mar 14, 2011
