| titleOfInvention | Process for the preparation of zeolite A for use in formulations based on two-component polyurthane resins |
| abstract | Zeolites of type A wherein all the cationic sites of which occupied by sodium, calcium and/or magnesium, potassium and hydronium cations, which exhibit the advantage of having a water adsorption capacity>=23%, which do not adsorb and therefore cannot desorb nitrogen, and which, incorporated in polyurethane (PU) resins, make it possible to increase the potlife of the PU formulations in which they are incorporated. Such zeolites are prepared by a process comprising bringing into contact an aqueous suspension of zeolite 3A, 4A or 5A, an aqueous solution of calcium or potassium salt(s) or solutions of calcium and potassium salt(s), and an acid solution, simultaneously or otherwise and in any order; and in then filtering off and washing the solid obtained, and then drying and activating the zeolite. |
