Vesiliimi

Vesiliimi is a Finnish term that translates to "water glue" or "water-based glue." It generally refers to adhesives that are primarily composed of water and a binding agent, often a polymer. These glues are characterized by their ease of use, low toxicity, and generally non-flammable nature.

The most common type of vesiliimi is polyvinyl acetate (PVA) glue, widely recognized for its strong bonding capabilities on porous materials like paper, wood, and textiles. Other formulations may include starches, dextrins, or casein as binders, each offering slightly different properties and applications. For instance, starch-based glues are often used in packaging and paper manufacturing due to their biodegradability and cost-effectiveness.

Vesiliimi is a popular choice for crafts, woodworking, bookbinding, and general household repairs. Its water solubility makes cleanup simple with water, a significant advantage over solvent-based adhesives. When applied, the water in the adhesive evaporates, leaving behind the solid binder that forms the bond. This drying process can sometimes cause paper or thin materials to warp, a factor to consider during application. The setting time and final strength of vesiliimi vary depending on the specific formulation and the materials being joined.
