GLOXIL iM16k MAM is a micro hollow glass shere whose surface has been modified with a special methacrylic functional group. The process parameters are selected in such a way that, on the one hand, anchoring to the surface takes place and, on the other hand, released by-products are removed as far as possible during production. Undesirable by-products, such as occur during in-situ mixing (i.e. during the direct addition of the additives), are therefore practically completely prevented.

During compounding, the methacrylic groups of GLOXIL iM16k MAM provides good wetting and very good dispersion in the matrix polymer. During curing of the unsaturated polymers the methacrylic groups of GLOXIL iM16k MAM react in the presence of redicals with the polymer.
