Substantially defect-free sound and vibration damping coating |
| 摘要 |
The present invention is directed to a coating composition comprising: (i) an aqueous dispersion of polymeric particles; (ii) a polyether carbamate compound; (iii) a filler material; and (iv) an microparticle; and wherein after application to a substrate and after curing, the cured coating composition demonstrates a composite damping Loss Factor of 0.05 or greater at a frequency ranging from 100 to 6,300 Hz and comprises a surface that is substantially free of defects. |

1. A coating composition for sound and vibration damping comprising: (i) an aqueous dispersion of polymeric particles; (ii) a polyether carbamate compound; (iii) a filler material; and (iv) a microparticle that is different from the (iii) filler material; wherein the coating composition has a viscosity from 60,000 to 160,000 centipoise measured at 20 RPM with a #7 spindle on the Brookfield viscometer at ambient temperature, and wherein after application to a substrate and after curing, the cured coating has a dry film thickness of at least 1 mm and is substantially free of defects. |
