In this group we can find one-component and two-component adhesives. The former contains prepolymers in their composition and cure under the influence of water or moisture from the air. In order to obtain a proper adhesion, binding materials with one-component adhesives is usually carried out in special presses, often at an elevated temperature accelerating the curing time.
In contrast, two-component adhesives contain two components (polyols and isocyanates) and are ready for use after mixing them in appropriate proportions.
