Definitions
- the present invention relates to a composition based on (meth)acrylate monomer.
- the invention also relates to the use of said composition for repairing and/or semi-structural or structural bonding of materials in the field of transport, marine, assembly, electronics or construction.
- Acrylic compositions are known reactive systems that crosslink by radical polymerization. They are used as adhesives, sealants and coatings. Radical polymerization is typically initiated by a redox system which, through an oxidation-reduction reaction, leads to the production of radicals.
- the majority of acrylic systems are two-component systems.
- the first component traditionally contains the reducing agent and the reactive monomers, and the second component contains the oxidizing agent. Once the two components are mixed, the reducing agent induces the cleavage of the 0-0 bond of the organic peroxide, for example, and initiates the polymerization.
- the (meth)acrylic compositions comprise a redox system of the peroxide (oxidant)/tertiary amine (reductant) type.
