What Is Waterborne and PVA Emulsion Based Adhesive for Wood Flooring
Waterborne and PVA emulsion–based adhesive for wood flooring is an environmentally friendly, low-VOC, high-bond-strength glue formulated specifically for bonding parquet, laminate, and engineered wood panels. It offers excellent tack, flexibility, and water resistance suitable for indoor flooring installations.
Description
This adhesive is a polyvinyl acetate emulsion modified with plasticizers, fillers, rheology modifiers and performance additives, enabling durable adhesion between wood and common subfloor materials such as concrete screeds, cement-based leveling compounds, and plywood.
Definition
A waterborne, polymer-dispersion flooring adhesive formulated with PVA emulsion as the primary binder, designed to deliver strong adhesion, easy spreadability, and controlled open time for professional flooring applications.
Overview
The adhesive provides:
-
Strong initial grab
-
Elastic bonding to withstand dimensional changes
-
Low odor and non-flammable structure
-
Easy cleanup with water
-
Compatibility with most indoor wood flooring types
Preparation of Waterborne and PVA Adhesive for Wood Flooring
Production generally involves:
-
Preparing the aqueous phase
-
Adding and dispersing fillers
-
Incorporating PVA emulsion
-
Adjusting viscosity and pH
-
Adding plasticizers and performance additives
-
Final homogenization and filtration
Making / Prepare / Processing
The manufacturing process combines mechanical stirring, high-shear dispersion, and controlled addition of ingredients to ensure a stable emulsion with uniform viscosity, film strength, and bonding properties.
Waterborne and PVA Based Wood Flooring Adhesive Manufacturing Process
-
Stage 1: Charge water + dispersing agent + antifoam
-
Stage 2: Add fillers (calcium carbonate) under agitation
-
Stage 3: Introduce PVA emulsion gradually
-
Stage 4: Add plasticizer (e.g., dibutyl phthalate alternatives), preservatives, thickeners
-
Stage 5: Adjust solids content and viscosity
-
Stage 6: Filter and pack into airtight containers
Formulation (General Guide)
-
PVA Emulsion: 35–55%
-
Water: 10–20%
-
Calcium Carbonate: 10–30%
-
Plasticizers: 2–6%
-
Thickener (HEC, HPMC, Polyurethane Thickener): 0.2–1%
-
Preservatives & Defoamers: As required
(Note: Exact ratios depend on performance requirements.)
Properties
