SYNERGISTIC FILLER COMPOSITIONS AND LOW DENSITY SHEET MOLDING COMPOUNDS THEREFROM

摘要

The present disclosure relates generally to resin formulations for sheet molding compounds. Particularly, but not by way of limitation, the disclosure relates to low-density thermosetting sheet molding compounds (SMC) comprising a treated inorganic clay, a thermosetting resin, a low profile agent, a reinforcing agent, a low- density filler, and substantially the absence of calcium carbonate. The thermosetting SMC are used to prepare exterior and structural thermoset articles, e.g. auto parts and panels, etc that have Class A Surface Quality.
