Penopac Charts

These charts combine the test areas and functions of a penetration and an opacity chart. They can be considered as universal test charts for research and development and quality control. Penopac Charts contain both sealed and unsealed areas. Sealed areas have a clear impervious topcoat which prevents penetration and unsealed areas have a semi-porous clay paper coating.
