Definitions
- the present invention relates to a composition based on (meth) acrylate monomer.
- the invention also relates to the use of said composition for the repair 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 crosslinking 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 results in the production of radicals.
- the majority of acrylic systems are two-component systems.
- the first component traditionally contains the reducing agent and 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 organic peroxide, for example, and initiates polymerization.
- oxygen inhibition one of the problems with this technique is oxygen inhibition.
- the oxygen present in the air in its triplet state will interact with the radicals formed on the surface of the sample, thus preventing them from initiating polymerization.
- This inhibition is expressed mainly on the surface since the oxygen penetrates little or no depth depending on the weight deposited.
- the polymerization reaction is often slow for surfaces exposed to atmospheric oxygen which, partially cured, often remain sticky.
- the present invention relates to a two-component composition

- composition A comprising:
