Cold Water Soluble PVA 2488 for Construction Putty And Tile Adhesive

This is a partially hydrolyzed polyvinyl alcohol (PVA) grade 2488, produced by HOPEWAY CHEMICAL. With a degree of polymerization of approximately 2400 and hydrolysis of 87–89%, it dissolves rapidly in cold water and is a primary binder for interior wall putty, tile adhesive, and waterproof mortar. It improves adhesion, water resistance, and crack resistance in cement-based formulations. Our PVA 2488 has been supplied to a Brazilian construction chemical distributor for over two years, achieving a 60% reduction in terminal product return rate due to reduced delamination and powdering.

Key Selling Points

Cold Water Soluble: Rapid dissolution in cold water facilitates efficient mixing and application in putty and adhesive production.
Optimal Viscosity (44–55 mPa·s): Provides stable viscosity for consistent batch control and smooth application.
Strong Adhesion: Enhances bonding strength between cement, fillers, and substrates, reducing powder falling and delamination.
Crack Resistance: Improves flexibility of dry mortar, helping to prevent hairline cracks in wall putty and tile adhesive.
Water Resistance: Forms a durable film that boosts water resistance, suitable for high-humidity environments.
Low Ash and Low VOC: Low impurity levels help avoid efflorescence and meet indoor building material standards.

Models and Options

This product is available under the model PVA 2488. For construction applications, we also offer PVA 1788. Custom mesh sizes (80–200 mesh) and packaging options are available to suit your production line.

Materials and Structure

PVA is manufactured by alcoholysis of polyvinyl acetate (PVAc). It is a water-soluble polymer in white powder/flake form with excellent film-forming and adhesion properties.

Applications

Interior wall putty
Tile adhesive
Waterproof mortar
High-viscosity construction glue
Thick coating formulations

Customization

We offer adjustable mesh size (80–200 mesh) to match automatic feeding lines, as well as custom packaging. Our technical team provides formulation guidance and remote online support to optimize your specific application.

Case Study

Brazilian Construction Chemical Distributor: A local distributor in Brazil has been using PVA 2488 and 1788 for over two years to produce interior wall putty and repair mortar. The uniform particle size ensures fast dissolution without agglomeration, improving production efficiency. The adhesion, water resistance, and crack resistance of the putty comply with local NBR standards, reducing the return rate by over 60%. Customized 80–200 mesh sizes and complete export documentation supported smooth customs clearance.

FAQ

What is the difference between PVA 2488 and PVA 1788?

Both are partially hydrolyzed, but PVA 2488 has a higher viscosity (44-55 mPa·s) and degree of polymerization (~2400) compared to PVA 1788. PVA 2488 is often preferred for applications requiring higher adhesion and thickening.

How should PVA 2488 be dissolved?

It is cold water soluble, but for faster dissolution, it is recommended to add PVA powder slowly to water with gentle stirring to avoid clumping. Heating can speed up dissolution, but high temperatures should be avoided.

What is the MOQ?

The MOQ is 5 tons. We accept FOB, CIF, and other trade terms.

Can you provide samples before bulk order?

Yes, we can send samples for testing. Contact us to arrange a trial.

Do you support customization of mesh size?

Yes, we can adjust the mesh size from 80-200 mesh to suit your automatic feeding system.

What documents do you provide for export?

We provide COA, MSDS, TDS, and certificate of origin to support customs clearance and meet local regulations.

What is the typical delivery time?

We maintain constant stock and can usually arrange shipment within a short time after order confirmation. For bulk orders, please contact our sales team for detailed lead times.
