POLYURETHANE-BASED COMPOSITION FOR THE PREPARATION OF RESIN

摘要

The present invention relates to a composition comprising: a composition A comprising: ○ at least one hydrophobic polyol P1 comprising at least two OH hydroxyl functions; ○ at least one polyol P2 having a molecular weight or a number average molecular weight less than or equal to 600 g / mol; ○ at least one polyol P3 having a molar mass less than or equal to 150 g / mol; a composition B comprising: ○ at least one polyurethane comprising at least two NCO end groups obtained from at least one diisocyanate chosen from meta-xylylene diisocyanate (m-XDI) and diphenylmethane diisocyanate (MDI). The present invention also relates to the use of the composition for the preparation of resin, in particular for the field of treatment of water or aqueous effluents.
