PURPOSE: Provided is a low-pressure molding, thermosetting resin composition comprising 0.5-15 wt%(w/w) of crystalline saturated polyester resin or crystalline unsaturated polyester resin. CONSTITUTION: The low-pressure molding, thermosetting resin composition comprises 0.5-15 wt%(w/w) of crystalline saturated polyester resin or crystalline unsaturated polyester resin. The resin composition comprises 5-30 wt%(w/w) of base, 15-45 wt%(w/w) of stiffener, 30-60 wt%(w/w) of filler, 0.5-35 wt%(w/w) of monomer, 0.01-2 wt%(w/w) of initiator, and 0.1-5 wt%(w/w) of releasing agent. The resin composition further comprises 1-20 wt%(w/w) of low profile agent. The low profile agent is at least one selected from polymethylmethacrylate(PMMA), polyvinyl acetate(PVAc), polyurethane(PU), polystyrene(PS), and polystyrene based copolymer. |
