Reaktiiliimaa

Reaktiiliimaa is a Finnish term that translates to reactive adhesive. This type of adhesive undergoes a chemical reaction upon application to form a strong, permanent bond. Unlike solvent-based adhesives that rely on evaporation, or hot melt adhesives that solidify upon cooling, reactive adhesives cure through processes such as polymerization, cross-linking, or a combination of both.

The curing process can be initiated by various triggers. Common mechanisms include the mixing of two components (like epoxies or polyurethanes), exposure to moisture (like cyanoacrylates or silicones), or UV light (like UV-curable acrylates). The specific chemical reaction determines the properties of the cured adhesive, such as its strength, flexibility, temperature resistance, and chemical resistance.

Reactive adhesives are widely used in numerous industries due to their superior bonding capabilities. They are found in applications ranging from construction and automotive manufacturing to electronics assembly and medical device production. Their ability to bond dissimilar materials, fill gaps, and withstand harsh environments makes them a versatile choice for demanding applications. The specific type of reactive adhesive is chosen based on the substrate materials, the required performance characteristics of the bond, and the environmental conditions it will be subjected to.
