The invention relates to an encapsulation composition for the storage or the confinement of waste which is toxic to health and/or the environment, comprising a resin composition containing at least one epoxy resin, and a hardening composition containing at least one polyamidoamine and at least one aromatic polyamine, said encapsulation composition having an aromaticity rate which is equal to, or higher than, 35%. The invention also relates to the use of said composition for encapsulating said waste.

Encapsulation composition for storage or confinement of waste which is toxic to health and/or the environment

The invention provides a powder pre-preg comprising as sole resin a vinyl ester resin having a Tg in the range of &#x2212;5 to +30&#xb0; C. and a melt viscosity @100&#xb0; C. in the range of 2 to 75 dPa&#xb7;s, which can be used in making a composite at a temperature as low as 80&#xb0; C.

Vinyl ester powder pre-preg

The invention relates to a coating composition for the storage or containment of waste that is toxic to health and/or the environment, comprising a composition based on an epoxy resin and a curing composition free from an aromatic amine curing agent. The invention also relates to the use of this composition for the coating of said waste.
