PVA-2488
(Polyvinyl alcohol-2488)
This product is a white granule or powder derived from the alcoholysis of polyvinyl acetate; it is a widely used water-soluble polymer additive in the construction materials industry. Even at low dosage levels (typically just 0.5%–3.0%), it significantly enhances the bonding, film-forming, and slurry-retention properties of mortar.
Four core functions:
Enhances initial tack and interfacial bond strength
Provides excellent film-forming properties, improving mortar flexibility
Improves water retention and workability
Increases cohesive strength and reduces the risk of dusting/powdering
Key application areas:
Interior and exterior wall putties
Dry-mix construction adhesives and tile adhesives
Gypsum-based plasters and jointing/leveling compounds
Mortars for external wall insulation systems
Various dry-mix coatings and repair mortars
