DI-COAT R-4721 / DI-COAT R-4721 LV (lower viscosity) Shore 90 D, room temperature curing, medium to high thixotropic coating for dielectric insulating applications. DI-COAT R-4721 is ideal for use on vertical or sloping surfaces where flow or drain-off cannot be tolerated. DI-COAT R-4721 is easy to use, and should be used on insulating applications where conformal coating is required. DI-COAT R-4721 LV exhibits similar characteristics to DI-COAT R-4721, but has a lower viscosity. |
