Setting by Chemical Reaction (Reactive Adhesives). The high molecular mass bonding substance is formed during bonding

2.1. Formation and Cross-linking of the Adhesive Film by Polymerization.

Two-pack polymerization adhesives: unsaturated polyesters with monomeric vinyl compounds, e. g., styrene or methyl methacrylate. No-mix adhesives and A/В acry­lates, applied without premixing. Uses: metals, plastics, silicate-containing materials. One-pack polymerization adhesives:

a) Cyanoacrylate adhesives setting under the influence of moisture or alkalinity. Uses: metals, plastics, silicate-containing materials, rubber, wood (high-strength spot bonds or small-area bonds).

b) Anaerobic adhesives. Special methacrylate adhesives. Uses: metals (threadlocking and bearing retention).
