Liimise

Liimise is an Estonian term that refers to the process of gluing or adhesive bonding used to join materials. It encompasses selecting an appropriate adhesive, preparing the surfaces, applying the adhesive, and allowing or enabling the bond to cure or set.

Etymology and usage: Liimise derives from the Estonian verb liima, meaning to glue. In technical and industrial contexts, liimise is used to describe the complete bonding process rather than a single adhesive product. The word is commonly encountered in Estonian manufacturing documentation and training materials and is often translated into English as gluing or adhesive bonding.

Applications: Liimise is applied across a range of industries, including woodworking, packaging, electronics assembly, automotive manufacturing, and construction. It is a general concept that covers fastening methods that use adhesives to join dissimilar materials, create seals, or assemble components where mechanical fasteners are impractical or unwanted.

Process and techniques: Effective liimise typically involves surface preparation (cleaning, drying, and sometimes roughening or priming), selecting a suitable adhesive type, and applying the adhesive by brushing, dispensing, or spraying. After application, components are aligned and held in place during curing, which may be air-dried, moisture-cured, or heat-assisted. Quality control often includes bond strength testing and inspection for defects. Safety considerations include ventilation and handling guidelines for volatile compounds.

Materials and adhesives: Common families used in liimise include epoxies, polyurethanes, cyanoacrylates, silicones, and acrylics, each offering different strength, flexibility, and temperature performance.
