(EN) RELEASE AGENT FOR LIGNOCELLULOSIC COMPOSITES
(FR) AGENT SEPARATEUR POUR COMPOSITES LIGNOCELLULOSIQUES
Abrégé
(EN)
Novel release agents comprising a carboxylic acid comprising at least six carbon atoms and at least one free carboxylic acid group and a polysiloxane comprising at least one organically bound active hydrogen group, which release agents are particularly suited for use in forming lignocellulosic composites prepared using an isocyanate adhesive. Processes for the use of such release agents in the synthesis of lignocellulosic composites prepared using isocyanate adhesives.
(FR)
L'invention concerne des agents séparateurs qui renferment un acide carboxylique ayant au moins six atomes de carbone et au moins un groupe acide carboxylique libre et un polysiloxane comportant au moins un groupe hydrogène actif à liaison organique. Ce type d'agent séparateur est particulièrement approprié à l'élaboration de composites lignocellulosiques au moyen d'adhésifs à base d'isocyanate. L'invention concerne également l'utilisation des agents séparateurs considérés pour la synthèse des composites lignocellulosiques qui sont élaborés au moyen d'adhésifs à base d'isocyanate.
