Abstract

Disclosed is a casting resin of reduced viscosity based on methacrylic acid esters with a high content of aluminum hydroxide as filler containing a mixture of at least one organosilicon compound with a functional group, at least one silicic acid ester, and at least one organic metallic acid compound of metals of Groups IVB and/or VB of the Periodic Table of the Elements. The functional group of the organosilicon compound is ethylenically unsaturated and bound to the silicon atom either directly or by alkylene groups. The casting resins of the invention have improved working qualities. Plastic objects and moldings manufactured from these resins have decidedly improved use properties.
