Introduction
Waterborne and PVA-based wood flooring adhesives are environmentally friendly bonding materials formulated to provide strong adhesion, flexible film formation, and excellent workability for parquet and engineered wood installations. These adhesives are widely used due to their low VOC profile, ease of use, and strong bonding performance on porous wooden substrates.
Production Procedure (Step-By-Step)
1. Preparation of the Mixing Tank
Make sure the tank is clean, moisture-free, and equipped with a low–medium shear mixer.
2. Water Phase Formation
Add the required amount of water and start agitation.
3. Addition of PVA (Polyvinyl Acetate Emulsion)
Slowly add the PVA emulsion while mixing. Maintain steady agitation to prevent coagulation.
4. Incorporation of Plasticizers
Typical options: dibutyl phthalate alternatives, glycol ethers, or environmentally compliant plasticizers.
These improve flexibility and reduce brittleness.
5. Addition of Thickener / Rheology Modifiers
HPMC, HEMC, or associative thickeners are commonly used to reach the correct viscosity suitable for flooring applications.
6. Incorporation of Fillers
Calcium carbonate or talc is added gradually to enhance body, coverage, and mechanical strength.
7. pH Adjustment
Use ammonia solution or a suitable alkaline agent to reach pH 4.5–6.0, depending on formulation needs.
8. Biocide & Preservative Addition
Waterborne adhesives require antimicrobial protection to prevent spoilage.
9. Final Homogenization
Mix until a smooth, uniform, stable adhesive is formed.
10. Packaging
Fill into moisture-tight buckets or drums.
