AN AMORFO PARTICULATED ADDITIVE FOR RESINS THAT HAS (1) A MOLAR RELATIONSHIP OF SIO {SUB, 2}: AL {SUB, 2} OR {SUB, 3} BETWEEN 2.1: 1 AND 3.3: 1, BASED ON THE OXIDES, (2) A DIAMETER OF MIDDLE PARTICLE BETWEEN 0.3 AND 10 {MI} M, (3) A REPAIR IN BALANCE (90% RH) NOT HIGHER THAN 10%, (4) AN APPEARING DENSITY BETWEEN 0.5 Y 1.2 G / ML, AND (5) A PH IN THE FORM OF A WATERPROOF SUSPENSION BETWEEN 6 AND 10. SUCH AMORPHIC PARTICLES CAN BE OBTAINED BY A CERTAIN ACCESSED TREATMENT OF A ZEOLITE PC WITH A SPHERICAL PARTICLE FORM, A DENTED SURFACE AND A RELATIONSHIP MOLAR SIO {SUB, 2}: AL {SUB, 2} OR {SUB, 3} BETWEEN 2: 1 AND 3.4: 1, BASED ON OXIDES, HAVING SUCH PARTICULATE LOVES BASICALLY THE SAME PARTICULATE STRUCTURE AS THAT OF THAT ZEOLITE PC AS WELL AS A DEFINED FORM. |
