COMPOSITION AND METHOD FOR PRODUCING A MATTE FINISH ON THERMOFORMED ACRYLIC SHEETS |
摘要 |
A composition for making a cast, thermoformable sheet or slab having a matte surface comprising a syrup comprising about 90% SSI—acrylic pre-polymerized syrup at 20% solids; and about 4-10% particles of about 10-15 microns in diameter of a copolymer of methyl methacrylate and ethylene glycol dimethacrylate or such particles of barium sulfate, calcium carbonate and/or silica. A method for producing a they article having a matte surface comprising mixing a syrup comprising about 90% SSI—acrylic pre-polymerized syrup at 20% solids; and about 4-10% particles of about 10-15 microns in diameter of a copolymer of methyl methacrylate and ethylene glycol dimethacrylate or such particles of barium sulfate, calcium carbonate and/or silica; heating the syrup; casting the syrup into a sheet; and thermoforming the cast sheet against a mold. |
