liimatyypin

Liimatyypin is an Estonian term used to designate a category or class of adhesives, grouped by bonding mechanism, chemistry, or typical applications. It is a generic concept rather than a specific product, and it appears in technical documentation, procurement specifications, and educational materials to compare different adhesives.

Common liimatyypid include structural adhesives such as epoxy and polyurethane, reactive adhesives such as cyanoacrylates and silicones, solvent- or water-based adhesives such as polyvinyl acetate and acrylics, as well as hot-melt and pressure-sensitive adhesives. Each type has characteristic curing or setting processes: epoxies and polyurethanes cure chemically through polymerization or cross-linking; cyanoacrylates polymerize rapidly in the presence of moisture; silicones cure by condensation; hot-melt adhesives harden when cooled; pressure-sensitive adhesives rely on tack and adhesion without a chemical cure.

Selection of a liimatyypin depends on substrate compatibility, required bond strength, flexibility, temperature and chemical exposure, curing time, and application method. Safety, environmental impact, and availability are also considered in industrial contexts.

Usage notes: in Estonian technical language, phrases such as liimatyypi omadused (properties of the adhesive type) or liimatyypi kasutusala (application area of the adhesive type) are common. The term helps avoid referring to a single brand and supports standardized comparisons across products.
