It is a water-based dispersion - a suspension of fine resin particles (most commonly polyvinyl acetate, PVAc) dispersed in water. Bonding occurs as the water evaporates: the polymer particles coalesce, forming a durable, flexible bond. Hence the alternative terms “water-based adhesives” or “evaporative adhesives.”

Frequently Asked Questions
What is a dispersion adhesive?
How long does dispersion adhesive take to dry?
It depends on the applied adhesive weight, substrate absorbency, and humidity - from an initial grab within a few seconds on a machine to full bonding after the water has evaporated. Parameters are selected according to the specific application.
Is Wikol a dispersion adhesive?
Yes. “Wikol” is a commonly used term in Poland for adhesives based on water-based polyvinyl acetate (PVAc) dispersions. Similar to the English Xerox name for a photocopier. Industrial dispersion adhesives work on the same principle, but their parameters are tailored to machine production rather than household applications.
What is the difference between dispersion adhesive and hot-melt adhesive?
Dispersion adhesive bonds as the water evaporates, while hot-melt adhesive bonds as it cools and solidifies. For high-speed production lines, hot-melt is generally better suited, while dispersion adhesive is often preferred for paper bonding where a longer open time is required.
What are the advantages of dispersion adhesives?
They are solvent-free, making them safer for workers and the environment. They provide a strong, flexible bond on paper and cardboard, spread easily, and, when the viscosity is properly selected, help prevent the sheet from wrinkling.
What materials are they suitable for?
Primarily for absorbent substrates such as paper, solid and corrugated cardboard, and paperboard. For difficult, laminated, and varnished substrates, we offer a separate range of specialized adhesives.
Do you offer bookbinding adhesives?
Yes, we offer bookbinding adhesives designed for the production of books, catalogues, notebooks, packaging, and other paper products.
What are pressure-sensitive adhesives used for?
Pressure-sensitive adhesives are primarily used in the production of labels, tapes, films, and other self-adhesive materials that bond to a substrate when pressure is applied.
