Display Charts/Spreading Rate | Elcometer 4695
| These charts employ time-tested, diagonally striped patterns, having a strong visual impact that emphasizes variations in film opacity. They are frequently used for hiding power display purposes, by means of draw downs or brush outs. Grey strips in Forms 8H-GW and 8K-GW provide reduced substrate contrast for use with low hiding power coatings. Spreading Rate Charts (Forms 8H and 8H-GW) are accurately 0.1 square meters (approximately one square foot) in area, and are used in brush out hiding tests at specified spreading rates as described in ASTM Method D 344. |
